Welcome!

I have faced a problem on my company printer there is an error that”has no internet connection” although everything is fine the network cable is working but I don’t know why it says. I have seen IP address of the printer there also the same error. Please let me know if there is any way to solve it. HPdesign jet T2600

I have mesh WiFi in my house and a playstation, the playstation is far from the main unit of the mesh to be physically connected to it. If I connect it to one of the secondary units via ethernet will it be any better than wireless connection?

So I seem to be leaking private ip ranges past my router. It makes it two hops before stopping in frontiers network. I would think my router wouldn’t forward those packets

What am I missing here?

traceroute to 192.168.0.1 (192.168.0.1), 30 hops max, 60 byte packets 1 192.168.1.1 0.305 ms 0.456 ms 0.615 ms 2 47.bbb.ccc.eee 8.737 ms 8.853 ms 12.638 ms 3 172.102.104.eee 12.520 ms 172.102.100.bbb13.637 ms 172.102.104.ccc 19.487 ms 4 * * *

They expand it as Automatic Repeat reQuest. but why? Saw in stackexchange that there's some lore to it; would be very happy if someone explains; thanks (i am a newbie to computer networking)

Hey all, computer networking is one of my weak points and I am not very knowledgeable about it so I would really appreciate some help with an issue that is driving me mad. I game, watch steams, and use discord calls a lot and I am experiencing an issue where at random times I will get a connection drop that only lasts a moment but it is enough to disrupt my streams, calls, and even boots me out of overwatch matches that will immediately rejoin. When it happens all my online steam friends pop up as if I had just connected to the internet all over again.

My isp is verizon, I get 300mbps no issues with speed. I am hardwired directly into the router. The router model number is CR1000B. I am using the ethernet port on my motherboard, not using a pci network card. Wifi is disabled. All drivers are up to date.

I have started keeping track of what I've tried so far but I am out of ideas of what else I can try or what to google...

-a few weeks ago I reset all network settings in windows

-today I have flushed dns resolver cache

-dns settings showed an Oculus program using my network when I havent used Oculus software or headset in months, I disabled and prevent the background process from running, it no longer shows network usage

-I have tried a different ethernet cable and a different port on router

-I am actively monitoring for disconnects on another pc using wifi. With steam open on both PCs we noticed a disconnect visible on my PC but not the other one. I havent noticed any disconnects on any other device in my home so I am fairly sure the issue is PC or router side for me and not on my ISP end

-lastly I re-enable ivp6

Nothing has worked so far and like I said I'm kinda bad at this stuff so if anyone could give me some insight or point me in the next direction I would be eternally grateful. I will happily provide anymore details I am able. I would even be happy to be pointed to a better place to ask for help if thats a thing.

I am looking for gigabit ethernet card that I would like to put it in my spare PCIE 3.0 1x slot. I have narrowed down my potential choices, which are Intel I226-V, I225-V or Realtek RTL8126. I keep finding horror stories about Intel ethernet cards of connection drops and compatibility issues.RTL8126, on the other hand, does not have much negative reviews which I think it is mostly because I could only find few.

Mind you that I do not have a switch to connect ethernet cable. I intend to use it as PC to PC. And my OS for both PC is Arch Linux (if any of this info helps).

Does anyone have any experience with RTL8126?

We have this network provider in our company and it’s getting tough to even load common websites like car part websites, ( not kidding ). Has anyone heard of this provider. Is there a bypass.

I have tried so many differnt things to resolve this issue with no avail. If i ping google servers in cmd, it shows 0 packet loss though, but once i fire up winmtr, it goes crazy bad. I can also feel it in games, its horrible. I pinged my modem, my gateway IP in winmtr, showed 0 packet loss. Once i start pinging google, or twitch, or game client, or anything out there, packet loss is crazy bad. ISP says they didnt find anything wrong on their end(of course), and the issue has to come from my end. They even said its my CPU lol. Im out here trying to enjoy my free time by playing some games with the bros, but its totally unenjoyable. Any tips? Maybe id see something i havent seen before..

When I type my IP in, gives me this error, ive tried multiple browsers. All I wanna do is portforward lol 🤔🤔

I´ve been using a B818 4G modem for some time. Now, I've updated it to a Huawei CPE 5G, which is now my main modem. I also have a Huawei AX3 router connected to CPE, and they form a mesh network. I know that B818 supports the Huawei mesh to some extent.

Current setup is:

CPE 5G -> Gigabit switch -> AX3

My question is that if i pull a network cable from the switch to B818 wan port, am i able to use it to extend the mesh network even more? I know that the CPE and AX3 support Wifi6 and B18 only Wifi5 but Wifi5 speeds should be enough for my use.

Huawei's manuals about the mesh functionalities are very poor. I was quite surprised that the current CPE+AX3 mesh even works.

Hi, I need some help as I am a networking noob. This is for my grandmother and I will not be there when the tech comes so I need to write down a list of questions for her to ask and have them check.

The issue she is encountering is that her internet randomly drops off and the only solution is to restart the router. I’ve tried unplugging it from power and undoing the coax cable. That did not solve the issue. I called her ISP multiple times and they said that the modem is receiving signal but she has 11% of errors being uncorrected. From my research this could be a number of issues.

What are some things that I can write down for the tech to check when he’s out here?

I appreciate your help!

Hello,

We have a NetBox in our environment where we have every network device(switches, routers, firewalls) from our infrastructure with current sw type and sw version.

We have scripts that are collecting those data every day at night and in case there was an update, it will update it in NetBox

I would like to automatically compare these against some list of vulnerabilities (Example: Cisco ASA v9.x.x) to find our if we are vulnerable. Is there some trusted, up-to-date source I can dowload and compare against?

Some structured data, like json will be great.

Thanks ;-)

Hi,
I need to find a device under £300/400 that can handle at least 50 IPSec tunnels. Essentially a gateway-to gateway/Site to Site. Each gateway will only have 1 device behind it.
Most devices I look for don't actually mention the concurrent number of tunnels they can do. I also wanted to know what is it that sets those limits, RAM, CPU, OS..?

Hello Reddit,

I'm hoping I can get some help from you experts.

I have a Starlink connection and I would like to create 2 networks. One for the private part of my house and one for the commercial activity adjacent to my house, on which people I do not know will connect (wireless AND wired, so I cannot use a guest network). The goal is that these people cannot access my private home devices.

From what I understand, I have to use VLANs. Right now for the private part, I have a TP-Link Archer AX73 as a router, and for the commercial part, a YuanLey 18 Ports PoE+ as a switch in which I connect a TP-Link Omada EAP225 as an access point.

Here is what I do not understand:

- Is it enough for me to buy a VLAN-compatible Switch like the Zyxel 8 Port Gigabit Web Managed Switch and create 2 VLANs, one to the Archer AX73 router and the other to the YuanLey switch?

- Apparently not because I read online that all devices must be VLAN-enabled for this to work, but what does that really mean? The Archer AX73 supports VLAN IDs, but nothing else. Same for the EAP225 access point. Is that enough?

- For example, does an unmanaged switch still need to be VLAN-enabled too? What does that mean as well?

Please explain like I'm five, because I'm a total noob.

Thanks in advance!

Hello,

I have a VPS that I haven't used for some time, however I still have available some time with it and I started playing around, but came across a problem that I didn't know was going to be so complicated.

So, I installed Proxmox (a virtual environment) on this VPS. All good, until... the network part. I created a bridged interface, the Proxmox default one, the machine lost connection to the Internet. Then I tried to create a bridge by myself and have the WAN interface of the VPS be the master of the interface. My idea with this didn't make much sense, I know, because what I would have to do is to SRCNAT the traffic from the VMs somehow, not have the traffic relayed to a new interface. The issue is that I don't know exactly how I'm going to do this.

The only thing that came to my mind (and the way I want to do it BTW) is having a router in a VLAN and then having all the VMs in that VLAN so there is no issue with the WAN interface, however, as I said, the moment I create a Linux bridge interface on the VPS, it loses Internet connection (and I'm not exactly sure why to be honest.)

Anyone has any idea on how I can proceed?

Thanks!

I just upgraded my Internet to 2Gbps when I run the speed test on the Router App I get 2Gbps but when I run the speed test on my Windows PC I get barely 1 Gbps, I check the router it only has one port on the back and yes it does support 2.5 + Gbps My motherboard does support 2.5Gbps as it is using the Realtek 2.5Gbps Family network adapter, and I am also using a cat 6 cable the router is approximately 12-15 ft from the pc. I have updated all the drivers for the network adapter and also updated bios and MB chipset any advice

Hi all, when i log into my Netgear RAX (I think 50 model) router and run a speed test, I get 250 down but when i run a speed test on google i only get between 60-75 down. The speeds feel more like 75 then 250. I have my laptop connected directly into the run so wifi interference isn't the issue.

Is my router dying? Is it possibly a setting I need to change? Thank you.

I have ~30 years experience in IT/electronics/coding/computers/etc. I'm only a noob to Cisco software, here's the situation:

I'm currently working with a non-profit tech group, and I'm pretty much the resident tech expert. Not long ago we received a big donation of networking equipment. This stuff is not very new---at all. My current task is just testing this stuff to make sure things all work. I won't get into all of it here; let's just focus on one device: We have a Cisco 1811 router!

Now I've worked with routers and such, and I know Cisco is a bit of a different beast, so I'm not surprised I'm having a little difficulty. I tried just connecting my laptop to the router via ethernet (RJ45) to one of the FE ports, but ipconfig showed no gateway IP and I'm not able to access the router config in my browser.

So apparently I have to connect via the console port--which on this router is RJ45 only. I have to find an RJ45 to USB cable, but in the mean time I also need to source some software. However, Cisco no longer provides downloads for this model (1811).

Now, I can live with using CLI if I have to, but is there a GUI for these devices? Either way, I can't get software from Cisco; could someone point me to a terminal utility I could use? (GUI would be nice too!)

Hii Know I am studying cyber security and got CEH certificate. Know I am interested in networking can I get into networking by the help of CEH certificate ? Can I get a job in networking by this?

I’m really tired of every wireless switch/router only having an app for control. I am looking for one that has the split bands (not some smart combined bands like Eero) and the ability to connect via a browser. Anyone know of any good hardware that matches?

I need some help setting up my network. I unfortunately only have coax fiber to my apartment and it is not really working

Because of my apartment having concrete walls and a second floor I need to use mesh devices or the Wi-fi wont work. The apartment has wall mounted LAN ports that if "activated" can be used to connect a device to the internet using and ethernet cable.

Currently I'm using these which are "deco m9 plus" if the link doesn't work.

Kicker is that the electrical cabinet that houses all the LAN ports for the apartment as well as the port that makes it so they wall mounted ports work, does not have a coax port in it, meaning that I have to connect my router to the wall and then run a ethernet cable from the router to the cabinet but that means the cabinet cant be closed.

Also the router has to be put in bridge mode if I want the mesh to work.

So my question is how do I go about this? The images is how I had to connect it currently but that throttles my internet speed by big amounts but it is the only way I found that circumvents the problems,

How it looks

How its connected

Spectrum/charter business internet with their goofy 2 box system. We get a new public IP, and everything works for 2-3 days. After 2-3 days we lose access to critical systems. the main financial bank login, time clock system, POS system, and my ability to VPN to the site, These all go down at the same time. Every time 3 days after swapping a public IP.

Tracert works, ping works. I can even get to the web server, since I'm seeing a redirect to a /login page, but I get a bad gateway error. Encrypted traffic isn't reaching this specific sites public IP. the easiest one to test is the banking website since thats just a URL. I can access this site anywhere else in the world. Accessing VPN also works for that 3 day window. Something changes on the Spectrum side and everything is broken again.

I've had multiple techs come out, recreate the issue using the static public ip. Each tech confirms its an issue with the backend of spectrum. Spectrum NOC engineers are spending more time trying to prove me wrong than actually looking for an issue.

Has anyone seen ANYTHING like this before. What was the fix, or resolution?

Hello,
I have a Zyxel 5g NR5103EV2 router, but unfortunately, the labels on it have been vanished. Since Zyxel 5G routers have unique webpage passwords for each device, there isn’t a universal password for this model. The router has a WPS button, and I already know the Wi-Fi password, so I am connected via both Wi-Fi and Ethernet. I’m trying to access its configuration page at 192.168.1.1 but need the login password. Does anyone know how I can retrieve this password using my PC or a command-line tool? Thank you!

Hey all, this might not be the right subreddit to post this, so feel free to tell me where to post it if so.

I have had an Acer predator Helios 300 for about 3 years now. Wifi has always worked great. Suddenly, as of a few weeks ago, my wifi no longer works. Doesn't matter if I'm connected to my Wifi or my phone hotspot, the network troubleshooter will say "No DHCP server was found" after connecting with no internet. My Killer Wifi driver is up to date, and I know it's not the network. Randomly and rarely when I restart the computer, the wifi will work until I restart it again. Also, about a week after the wifi stopped working, my secondary SSD drive was disconnected for some reason, and I had to get in my laptop and reconnect the pins. Maybe that has something to do with it, or just a strange coincidence? What could be causing a DHCP server not to be found? DNS server is also set to automatic. How could I fix this? Anything helps.

Thanks!

Ever hear the phrase 'know just enough to be dangerous'? ...yep, pretty much 😟

So, I have a device that I may have locked myself out of and would prefer for that to not be the case. Not sure how I got here, but here is where I am.

Device is a 'cloud gateway' type device and is still connecting to the local network. the cloud management site shows a last known configuration as follows:

IP address: 192.168.0.233 Gateway: 192.168.68.1 SubnetMask: 255.255.252.0

So, it's my belief that the netmask is what's preventing the device from connecting and now that I think I know what the problem is, I'm finding it a challenge to re-create a network environment where the device can be contacted for reconfiguration and have finally reached the point where I'm hoping for an assist from someone that knows more than I to tell me if recovering is even a possible thing...

...so, what says you? Halp? Plaese?

My router is 10m away from my pc and in the way is a wall. I tried EVRYTHING from cmd command to installing apps on my windows pc. I bought a new WiFi dongle and installed new drivers. I check ping on my phone and it’s around 30, I check it in my pc and it’s 20 but every 5 seconds a ping spike. People in desperate, WHAT SHOULD I DO????

My main reason for this post is to try and figure out why one computer has a slower upload speed while another can read the speeds at the promised speed from my ISP even though the computer with the slower speed has the hardware to support said speeds. The attached photos will have the speed from the router which i should be getting and the other is what i am actually getting through ethernet

https://preview.redd.it/jhir6mecg33e1.png?width=1290&format=png&auto=webp&s=97409c0b4396fcebe080e9d4413444c2b8a8c33d

I had fiber installed this past week with a 1GB plan and the download speed is constantly around 945mbps while my upload speed varies between 350-500mbps. I am not saying the speed is slow but the speeds should rather mirror or be close to parallel. The router itself is seeing (984mbps download/ 955mbps upload) so that rules out the ISP side, The technician that installed the line also ran a speed test on his personal gaming laptop using the same CAT6a cable (2ft in length) and was getting 900mbps+ down/up consistently. This led me to believe there is some settings in my network that may be throttling my speed.

My hardware can support these speeds so i must be missing something.

Things i have done so far which is a lot so i may be missing a few steps i have taken.

1. Gone into my ethernet properties> configure> advanced tab

-Disabled any energy saving properties

-Interrupt Moderation DISABLED

-Interrupt Moderation rate OFF

-IPv4 Checksum Offload DISABLED

-Large Send Offload (IPv4) DISABLED

-Receive/Transmit Buffers Values (512)

-Speed & Duplex 1.0Gbps Full Duplex

-Ultra Low Power Mode DISABLED

My desktop is a custom built PC

Motherboard: ASUS ROG STRIX z370-E Gaming (1GB ethernet port)

CPU: Intel i7 8700K

Ethernet Cable is a CAT6a provided by the router

Router: Eero Pro 6E

Open to any other suggestions as i have hit a roadblock with my technological skills

TIA!

As far as I know, with NFS you can share a directory. Then, on the client side, you mount that directory on a local one. However, you can't, for instance, format that drive with a different filesystem and such. So, is there any way to do this? Is it possible with iSCSI, what about being possible at all with NFS, is it?

Thanks!
