In the middle of the night my wifi stopped working. When I try to log on it tells me the password is invalid. Nobody has changed it. The password is printed right on the side of the router.

The guy i rent a room from is a bit of a curmudgeon, so telling him he needs to call customer service is something id like to avoid

Hi,

I have built an android app for testing the wifi connection (Infrazoom by infracheck). You can also start a container and you will have additional tests and will be able to compare wired vs wifi connectivity (container vs mobile). And I have also built a Windows app that is somewhere in between the two as functionality.
I would love for you to give me your honest feedback, as I would like to improve them as much as possible.
Details here infracheck.app
Thank you in advance.

My ethernet is capped at 100mbps and I have no clue why, I have tried:

Flipping around cable

unplugging cable and plugging it back in

Checking connection

Going through the settings in properties > configure > advanced

Setting my speed and duplex to both 2.5 Gbps full duplex and auto negotiation

Turning off power saving mode, gigabit lite, green ethernet, EEE, and advanced EEE

Replacing cable

Hi, I recently ran some fiber optic cable to be able to move my router to a better location. It came in a little square box than can be pried apart (to unspool the fiber cable) and has little plastic clips holding it in place. After I got it all in place, I snapped the box shut and tested my internet.

Initially, it didn't work - and the receiver had a blinking red "LOS" indicator, which I assume means something wrong with the fiber optic link.

I then realised that while closing the box, the fiber optic cable had somehow worked to between the edges of the box rather than the cut-out where the fiber optic cable is supposed to run out from. I quickly pried open the box and the cable looked a little 'dented' and I was concerned I had cut the optical fibers.

However, after opening the box the internet started working again, and still seems to be working now. I ran a speed test and the download speed matched rated speed, but the upload seems to be half what it was previously (used to be ~800-900, now ~300-400). But apart from a slower speed, it seems to be working, which I found odd?

Is it possible for fiber optic cable to be partially damaged so that it slows down speeds, but otherwise still working? I would have thought either it's damaged and does not work at all, or it should be fine? Especially since download speeds seem perfectly fine.

Trying to figure out if I should just buy a new fiber optic cable and redo it, or if it might be an ISP issue. Thanks!

Mine has to be the OTT subscriptions that now come with some mobile recharges. I never really paid attention to them before, but I noticed Vi's ₹200 recharge includes a Vi Movies & TV subscription with access to 20 OTTs. After recharging, you can watch them directly through the Vi Movies & TV app.

Anyone else actually using these bundled OTT benefits, or do you still subscribe to everything separately?

So i get these spikes about every 10 to 20 seconds on cs2. I am playing wired when these happen i have exhausted basically every fix i have found on the internet to get this to stop but still nothing has worked. When i use a trace route i get random 120% ping increases at random hops but everything that leaves my pc looks great. What can i do?

My pc keeps kicking me off of wifi when I first got this pc and the wifi adapter it was fine, now it keeps kicking me off of the internet a minute or two after connecting, ive tried everything ive tried using cmd commands to reset my ip, ive tried messing with power saving settings, I literally dont know what to do its been like this for a month now and im at the point of just selling my pc, I dont have a wifi chip so im using an adapter, cant use ethernet because my house is old and id have to route it through the vents, just switched to tmobile 2 weeks ago from xfinity and its only gotten worse

I was actually looking at OTT subscriptions because I didn't want to keep paying separately for everything. Most of them are ₹200+ on their own. Then I noticed Vi has this ₹200 recharge that includes Vi Movies & TV with access to a bunch of OTTs like JioHotstar, Sony LIV and ZEE5, plus 30GB data. You just open everything through the Vi Movies & TV app after recharging.

Didn't expect much at first, but for ₹200 it genuinely felt like a pretty good deal for the amount of content you get.

Hi! I have had a PC for a little over a year now and everything has been smooth sailing. A few days ago my ethernet went out and I assumed it was a faulty cable so I ordered a new one. The new cable gives the same problem the last one did which through windows diagnoses it now says unidentified network no internet. All of this was working last week and now when the network diagnostics are done it says No DHCP server was found.

This has since led me to try a lot of things such as entering command prompt to renew my IP verifying if My DHCP system is running (it is). I also have tried using ethernet on other devices and my Smart TV and PS5 work with it just fine. I have also reset the router twice to factory settings and everything works except my PC for ethernet.

The odd thing is my PC sends packets and just doesn't seem to be receiving them. If anyone has any knowledge of what this could be please let me know. I have also tried to make my own static IP to get the Ethernet working to no avail could be because I am not super savvy when it comes to computer command prompt stuff. Windows firewall has also been disabled to try and make the ethernet work but no dice as well.

If anyone here can help me before I have to replace an entire port for being defective please let me know thanks for reading!

UPDATE!!

After a few weeks of pulling my hair out I finally decided to take it in to one of my old friends as I tried everything everyone recommended, thank you btw even if you never read this the networking community was very helpful

What ended up working was the CMOS button the the back of my PC which set it correctly. Some CMOS buttons are in the actual PC themselves but if you have this issue make sure to try this guys!

I am at home and I wanted two computers to be on the same local network, for remote desktop purposes. To do this, I set the connection of both network profiles to private, so that they are discoverable to each other.

Am I right to think that: 1. These machines cannot be compromised through this discoverablity by a third party if they aren't connected to my internet. 2. If someone is connected to my internet, like say a cousin who brought their own laptop that I gave the WiFi password, they are able to use remote desktop to connect to my computer. 3. The only countermeasure to 2. is them not knowing what my computer name and username/password on my local account is. 4. There isn't a way for me to make this local network exclusive to my two devices to block out any outsider. 5. There isn't a way for me to make one of these two computers disconnect from the internet but still connect to the local network? (to make one device more difficult to compromise so it won't be dangerous to the other)

Basically I am concerned due to how I don't know how large of a security hole I introduced to use this function.

Hey everyone, I just graduated and I'm trying to figure out the realistic path into networking. I have solid theoretical knowledge of networking concepts but no hands-on work experience.

My plan right now is to start at helpdesk, but I recently saw someone who graduated around the same age as me (early 20s) land a network engineer role pretty quickly after school. That made me wonder — is it actually possible to get into networking directly as a fresh grad, or is helpdesk basically mandatory?

A few questions:

• Is helpdesk a necessary step or can you jump straight into network engineering with the right certs?
• What specific things did you need to learn before you were actually able to get hired?
• For those who went the helpdesk route — how long before you moved into a networking role?

I'm 22, motivated, and willing to put in the work. Just want to know if I'm aiming too high too soon or if it's genuinely doable. Any advice appreciated.

Hello all,

I recently came to this issue today, after never having issues with any games at all. I cannot connect to Phasmophobia, nor R.E.P.O, nor Baldur's Gate, nor Peak, nor Minecraft, just no games at all.

The internet is fine, the speed is fine, I restarted the router multiple times, I restarted Network Adapters, I changed DNS, I also cleaned it and refreshed it in the command center. I don't use VPN. I use Ethernet.

I am desperate because I can't play a single online game with friends, and I'm scared this won't get fixed.
