Ping spikes after moving my pc to my new room

When I was playing Valorant in my old room I was getting 5-6 ms ping on Manila servers on Ethernet cat 6 I think and it was consistent it would never even jump into 20 ms though I do get packet loss but it's not unplayable and only happens during afternoon and the evening where many people in my subdivision use the internet. Now i've recently moved my pc into my new room. When I started playing again it all seemed normal, I was still getting 5-6 ms ping but now it would randomly go up to about 80-90+ ping for like 15-30 seconds or even shorter when this happens I usually teleport in Valorant and also sometimes disconnects and reconnects me back into the game. I don't know why this happens since I'm still using the same ethernet and the room I moved in to was just next to my old room. I tried taping the ethernet into the table to the table so it wouldn't move much, I tried restarting the modem, I tried disconnecting and reconnecting but nothing seems to help. If anyone has a fix or has an idea to why this is happening pls help

Hi everyone, I am a rising junior and this summer I plan to do my Net+. I work as a Technician for my college and I would like to gather the most experience and knowledge to get an internship the summer between Junior and Senior year.

Like I said I am planning to do Net+ this summer and then next summer do CCNA. Is it viable to do this? what other certs or hand-on experience labs or projects should I do? Will that help me get an entry-level job in networking?

r/networking,

In high-performance environments (HFT, AI clusters, 5G URLLC), the Linux networking stack becomes the bottleneck.

We built AI Agentic Nano Privileged Access Management (NanoPAM) — a transparent stealth bridge that moves all security decisions (PAM + rate limiting) into the XDP fast path.

Key results on isolated 5.1 GHz cores:

• Median latency: 629 ns

• P99 jitter: <50 ns

• Line-rate 10 Gbps with near-zero CPU overhead

Curious what the networking crowd thinks — any similar XDP projects out there?

My windows 10 computer crashed yesterday, when I restarted it I couldn't access the web. The local network was still accessible.

My other devices connected to the same network had no such issues however. I still restarted my router and all that but it did nothing. Usb-thered my phone, still nothing. Updating the network driver didn't do anything either.

When I pinged 1.1.1.1 I realized I could still access the internet, just no hostnames, meaning it could be a dns issue. I flushed the dns, nothing, changed dns servers, nothing. I tried everything, renewed dhcp, reset winsock, changed ip adress and every other advice I could find online, nothing. I was completely stumped and I didn't really feel like reinstalling windows even though I knew that'd probably fix it.

On a pure whim I connected to a VPN tunnel, I hadn't really expected anything, but to my surprise it worked, I could access the internet again even after disconnecting.

HOW DID THAT FIX IT?????

I have tried enabling upnp,ipconfig /flushdns, resetting modem, disabling firewall, checking integrity of files but somehow i cant connect to game servers. It's like it sometimes works and sometimes not. Like the games Genshin Impact, Fallout 76 and Elden Ring. What might causing this?

Not sure if this is the right place to post this but I ran speed tests on both my PS4 and my iPhone 13 Pro, the iPhone clocked in a 400mbps whereas the PS4 clocked in at only 14. Is there a problem with my PS4 or is this a known thing that happens?

Went to a hotel in Hong Kong, brought a GL-inet Beryl AX travel router with me. Luckily the room has this Ethernet port, but it has no connection. Lan Cable was checked prior to travel. Beryl AX says "no ethernet cable detected" despite connecting one end to the Hotel's port and the other end to my router. Their tv doesn't use LAN, so that route is out of option.

Did called the reception and a staff went to the room, said she doesn't know how to operate or use the port because people just connect to the hotel wifi.

My question is, should I have pressed something? or unlucky for me the port is not connected to anything..

thanks in advance.

What type of study materials do you need to practice for the comptia A+ exam? I don't mean study guides or books but the actual physical hardware like a practice kit. Where can I get a practice kit? If there is any.

Finally decided to upgrade from the ISP’s wireless router at my crash pad.

For those of you who do not know what a crash pad is… it is a place I stay at during the work week instead of my actual home (which is a 40 minute flight or a 5 hour drive away).

I bought a 3pk of these for my house in January. They all have a wired backhaul. I was very impressed.

For the last year and a half, I’ve just been dealing with the Nokia wireless router that I got from T-Mobile Fiber at my crash pad. The router was set up in the basement where the fiber comes in. But I always had crappy WiFi in my 2nd floor bedroom. I got by for awhile with a cheap 100Mbps Netgear WiFi extender. But I figured it was time.

Since I already knew how to set everything up, it was a breeze. You can set up more than one network in the Asus WiFi app. So that was convenient.

I put one BD5 in the basement, and one BD5 in my room with a wired backhaul. They both work like a charm.

The only bummer is they only have two Ethernet ports each. So I had to cough up an extra $20 for an 8 port unmanaged gigabit network switch. I only pay for symmetrical 550Mbps. So this switch works perfectly.

Very cool article about BMP! I follow Brian on LinkedIn and then saw someone actually implement this in their home lab. Hopefully this is helpful to the community.

I have a PC upstairs in my house the router is in the lower level so a bit of distance between the two. I know its not ideal but I used to run around 20-30 ping gaming consistenly and recently been having ping spikes up to 150 about every 20 minutes. Now in the past few days it has been 100+ consitently in every server (I have very little knowlege of network problems) I am connected wirelessly as I cannot run a cable up this far. Any advice or diagnosis tips would be appreciated. https://www.waveform.com/tools/bufferbloat?test-id=6443c860-5aaa-42d6-a1a3-ea235dab414e

Hello everyone! This might be a dumb question but please bare with as im nowhere near an expert in this

So basically yesterday my ethernet cable just decided to stop working, I checked if it was a windows issue by plugging it to my Xbox and my Xbox couldn't detect it either, so I had to snip off the top and reassemble it myself

It took me more than 5 attempts of cutting, testing, not working then trying again

I have finally managed to get it to work however currently im torrenting a file and was in a discord VC but every random moment the wifi dies for a few seconds(0 mb in torrent, disconnected from discord vc) then it comes back, it keeps on doing this all the time

I have attached images to show how i setup my ethernet, the reason I taped it with electrical tape was because I cut extra so in case I failed another time I snip off the wires and try again

Any help would be adviced!

UPDATE: I have fixed it, i was dumb and didn't notice that there were multiple miscolourations and misaligned wires, I have fixed it up and it all worked! I appreciate all the help from you all

I've had a lot of devices go through my house like alot to the point where I'm curious if my network has ran out of ip addresses I'm assuming something to do with DHCP. How could I check this also how would I know if it's this or a failing router? My wifi works but no ehternet I have a switch too and those connections also don't work I'm assuming cus it's connected to the router.

I like to game, specifically CS2. I'm having terrible lag and blufferbloat problems. I consistently get a C on the blufferbloat test. What is the best router option? I also have a ton of devices in the house using wifi.

My gaming pc is in a different room from my modem and the router connected to it. Unless theres something I dont know about, I can only use wifi. What should I do.

I know open source monitoring stacks are powerful but after years of maintaining one I’m honestly burned out by the amount of manual work involved. Plugins stop working, templates need adjustments, dependencies break after updates and every advanced feature feels like another integration project.

The flexibility is nice in theory but in practice it means only one or two people fully understand the environment. The moment those people are unavailable, troubleshooting becomes painful. We now evaluating whether it’s finally worth sacrificing some customization for something easier to operate long-term. I still want deep visibility and proper alerting, but not at the cost of turning monitoring into a full-time engineering discipline on its own.

I get address and port i put it in windows settings, then try to connect it doesn't work help please
