Wifi Randomly Disconnects when doing many things, mainly streaming vid

Bigbminus · 01 Apr 2014

I'm going to start from the very beginning, and use as much detail as possible, because this is my final hope. I have seriously tried everything. I'm not the most tech smart person but I am willing to try whatever else I am suggested.

I have comcast and a d3 modem. I have a linksys router EA6300 running firmware version 1.1.40.153731

I have a Asus G74sx laptop running windows 7 ultimate 64bit.

I have a Intel Centrilo Wireless N 6150 Wireless adapter

Never had a single problem ever, I play WoW, use ventrillo, have steam open, and constantly browse reddit and youtube. For years no problems.

Two weeks ago i started getting strong interruptions, they would last for about ten minutes, It was primarily when I was in a game of League of legends or streaming a youtube video. I just thought it was me putting to much on my internet as my wife also uses her ipad to watch netflix.

However now it is frustrating me so bad. When I am just browsing sites it will only kick me off occasionally, however if Im connected to ventrillo, or streaming a youtube video its pretty much a sure thing to knock me off.

I first made sure all other devices were working fine and they are. Ipad stays connected, our phones stay online. I reset my modem, and router and called comcast to make sure they didnt see any interuptions on their side and they did not. I have the router about three feet from the modem, the cables are connected fine, and my laptop is only about 4 feet from the router with no walls in between or any other devices around.

I completely wiped my hard drive, i have Kaspersky installed, i manually downloaded the drivers from intel to make sure they were up to date. I have WPA2-psk security on my wifi. There are literally no other programs or files on my computer except, steam, wow and ventrillo and google chrome. I have tried changing the power management on my network adapter to not let it go to sleep. I tried running the admin command prompt with netsh winsock reset catalog and netsh ipv4 reset reset.log and restarting my laptop. I have tried changing the channel on my wifi to 4. I took my to a friends house and his wifi worked perfect on my laptop. I took replaced my wifi card (5 bucks on amazon, not bad) and still the problem persists. My comcast plan allows me 25Mbps although soon ill be switching providers. I seriously have no idea what the problem is. I took it to a local computer store (good reviews, nice older couple) and they kept it for a few days and didnt charge me anything but said they could not find a single thing wrong with the laptop.

Lastly when it disconnects the wifi goes from 5 bars down to 4 and then a little yellow hazard sign comes up. I run troubleshooting and it tells me different things, sometimes its something along the lines or "Reseting Wireless Adapter" or "The Default gateway is not available" or "A connection is broken between your modem, router or wireless adapter"

I am so frustrated and confused I really have no clue what to do.
I have seen a few people attaching ipconfigs to their files so i thought i would do that but seriously anything anyone can help me with would be amazing and i would name my first born child after them....probably.

Edit : Just another note, forgot that occasionally the troubleshooting will tell me something along the lines of The Device is not set up(microsoft.com) to receive access to The World Wide Web.

Welcome to the Seven Forums.

It sounds like the laptops has worked just fine on two other networks (friend & service shop). You might try putting the Linksys AC/N router in the N mode only. You might also take your router to your friend's home and test things there. If your router/laptop works while in another home, then perhaps some type of interference has shown up at your place.

Sometimes the Wifi card can be on its way out, as it gets quite hot. Mine used to drop out. i replaced it and the problem was solved.

Yep, they do go bad, but the OP mentioned:

And the disconnect problem does not happen on two other networks. I'm guessing the the laptop is okay.

It sounds like channel crossover from the neighbors. Channel crossover is a common problem in crowded areas and can usually be eliminated by checking the channels being used in your area then make a channel selection based on which channels they are using.

I would check the wireless landscape in the area then make a channel selection based on what inSSIDer tells you rather than guess at which channel to use.

Download InSSIDer

Thanks guys i just got home, i will try changing the linksys to N and ill DL that InSSIDer and check it out and post back to you guys.

Bigbminus · 02 Apr 2014

So i changed my linksys router to Wireless N only and i downloaded InSSIDer (and almost some unwanted search engine lol) and I got the following result, not gonna lie im not 100% on what im looking at but since my router is set to channel 4 and it shows me "The Silence of the LANS" (>.>.... dont judge me haha) at the 40 i would say im ok? If you guys think otherwise i shall try whatever. On the post talking about the heat level on my card it IS rather hot where I am however the fan never sounds like its working super hard but if the problem keeps up i may start directing a fan onto my laptop during the sweltering hours! Will post if the problem persists... lets hope it doesn't.

I'll let chev65 comment in the info in the screenshot.

Next time, you might want to press Alt + Prnt Scrn. Doing that should place an image of the active window into the OS clipboard. There is no need to redo/re-post the screenshot; this is just FYI.

Funny SSID

Haha thank you! I love learning shortcuts

*Edit: Also 4 hours strong with no interruptions, if this works fine till tomorrow ill happily mark this as solved!

unfortunately this did not fix it although i am noticing a few things, i went in and put my DNS to googles DNS and set up my IP settings directly based off my ipconfig. However now it seems to work fine except for when i join ventrillo. the moment i join it freaks out my entire net, tried reinstalling and verifying info on that. Nothing, although in 6 days i leave my internet behind and switch to a new provider when we move so maybe something will change then. so confused.
