r/Network

​

My Ethernet connection doesn't actually disconnect. Windows still shows that it's connected, but the connection completely stops working for about 1 second and then comes back. This causes lag spikes and sometimes disconnects me from online games. I've already tried a different Ethernet cable and updated/reinstalled the network drivers. Has anyone experienced this or know what could be causing it?

Is there both an easy and practical way to setup a temp WAN connection using a cellphone when the internet goes down on a pfsense firewall? Ideally the situation would be where someone wouldn't need to make firewall config changes to get it working after initially setting up this backup solution.

I looked online and people are saying its a thing but how difficult is it to do with both an iphone and android phone (I heard android is easier but some phones are iphones)? The ideal situation would be were the internet goes out and someone can plug their cellphone into the firewall and the home could get internet again (a lot slower speed but having some internet is better than none).

Everyone's talking about Ansible, NetBox, pipelines, GitOps.

But honestly? Half the teams I see trying to automate haven't got a reliable source of truth, documentation that's actually current, or any real agreement on how changes should be made in the first place.

You can't automate chaos, you just get faster chaos.

Sometimes the right move is to get the basics solid before touching a tool. Know what you've got, document how it actually works, standardise the manual process first.

Automation should make a good process faster, not try to fix a broken one.

Am I wrong?

I would like to ask some advices. I’ve been working as Network Product Support for 5 years. The job is not really about network at all, basically just support on the product (NIC) and handle customer’s issue. I want to grow my career in network field. So, i took CCNA and CCNP and passed both exam.

This is the real struggle. I don’t hv any experience in configuring or troubleshooting in real world network field. I never touch any switches or routers. I’ve failed in many interviews because they are demanding for experience role.

Where should i start?

Bonjour mon ethernet se coupe au bout de 20min d’allumage du pc, et quand je regarde pour faire un diagnostic m, ça me met qu’il ne trouve pas ma passerelle par défaut
Aidez moi car je n’arrive pas à trouver la solution depuis 1 mois

hello…I’m starting a job from home but it requires a Ethernet cable/hard wired connection. the router is to far from my room does any body have any advice or knows ways to have a hard wired connect in my room? I’m seeing things on portable ones I can plug in my room then connect a Ethernet cable. just wanted to see what other people do in this situation. I don’t have a Ethernet plug in my room. just regular outlets and the router is elsewhere not in my room and I don’t want a long cable to have to attach….please and thank you

Both me and my stepdad have had the same issues with our TP-Link Gbit switches. They were cheap and we didn't have high expectations but we both kept losing Gbit speeds down to 100Mbit over and over again. Nothing wrong with the cable, it just drops the connection speed randomly. We've both gone and bought a different cheap brand, we don't use any advanced features when it comes to the switch we have connected to our routers.

Hi I've been trying to acces my network for days and I got this error Ethernet doesn't have a valid IP address.

How can I fix it?

Im using a Mercusys MR50G router

I have 2 laptops, one for personal use and another for work use. The personal laptop's internet speed remains consistent no matter which network I connect to be it at a cafe, home, relative's place etc. The work laptop however behaves differently. Have to use GoodAccess VPN for work and when I connect to the Wifi at my home, the speed goes rock bottom. Though that isnt the case if I connect to other networks at other people's houses for example.

Confused at what to do here cause I cant pinpoint what the source of the issue is.

Hello everyone,

I have just completed my BCA degree and am trying to map out my career path. I am very interested in becoming a Network Engineer, with the ultimate goal of moving into Cloud Engineering or Cybersecurity down the line.

However, I am feeling quite confused and stuck. When looking at the current job market, it seems like software development and data analytics roles have frequent hiring and a high volume of fresher openings. On the other hand, entry-level networking roles seem much rarer and harder to come by.

I would really appreciate some guidance from the community on a few questions:

• Is Networking a good foundation? Is starting as a network engineer a strong, viable pathway if my long-term goals are Cloud or Cybersecurity?
• Job Market Dilemma: Should I pivot to a more "traditional" path like development or data analytics because of the higher hiring frequency, or is it worth fighting through the competitive job market for a networking role?
• Fresher Strategy: What specific skills, projects, or certifications (like CCNA) should a 2026 fresher focus on right now to stand out for entry-level infrastructure roles?

Thank you in advance for your advice!

we're rolling out a new phone system and I keep going back and forth on whether agents should use VPN for calls.

some of our people are in countries where we can't have direct SIP access because of firewall nonsense. but also VPN adds overhead and latency which is the last thing you want for voice.

the platform has their own WebRTC stuff and honestly it works pretty well without VPN in most places. tested it from like 5 different countries and the quality was fine. but security is always the excuse for everything.

I had a meeting yesterday where manager was like but what if someone intercepts the calls. I'm like it's encrypted it's literally encrypted. we use TLS and SRTP what are you gonna intercept.

but I'm still getting pushback from the security team who want everything tunneled even if it breaks the calls. and they're not the ones dealing with the complaints when quality drops.

curious what you guys are doing. voice over VPN or direct internet access. I'm leaning towards direct because it's simpler and the quality is better. but maybe I'm missing something

I was downloading some mods from Nexusmods for Skyrim a few days ago and suddenly my internet turned off on only my PC. My wifi, tv, PS5 and other computers are working fine. It's only my PC that just stopped having internet.

I have tried everything suggested so far. Everything physical, replacing the cables etc rebooting the modem and router etc.

On the PC I tried resetting the drivers, by deleting them and rebooting. I tried to do the cmd IP stiff but I got back Error 5. I went into the registry to try and solve Error 5 by giving more permissions but without succes.

I feel like I'm at my wits end. I've tried so many different options.

I have a mesh wifi network and my pc is connected through cable from one of these mesh points. It's not possible to change this configuration, but I'm sure these towers have a great connection. As all my other devices work through these mesh points.

Any one? Please.

Hey all!

My team has recently noticed a dramatic (almost absolute) crash on metrics from RU geo on our application.

We tried debugging it a bit with VPN on Russia but see no issues, however 99% of the traffic from RU is not passing correctly.

Are there any limitations on AWS IP's or something along these lines that people are experiencing?

Our users are not blocked/failing to access S3 files using cloudfront CDN's.

Would love any info on the matter / hear if any1 else experienced this in the last year or so
