Wireless Network Issue

post #1 of 40
Thread Starter 
I'm having a continual problem with my wireless network and it is starting to really stress me! I have a wireless router downstairs (Netgear DG834G), and connected to it (wirelessly) are my rig, my PS3, and my housemates computer. Now, my internet works absolutely fine, barring the old slow speed from being on a congested adsl network, but if I download torrents, or play online games, basically putting some stress on my connection, the network drops out completely on my rig. If I search for wireless connections, it cannot find any in range, even though my PS3 and housemates computer are still happily connected and using the internet. Device manager still claims that my wireless network card is working properly. The only way to solve this is to reboot my rig, then it once again connects and is fine until the next time.

The fact that this happens only on my rig, and not my housemates, even if we do identical things, led me to believe that it was my wireless card that was to blame. However, I am now on my third wireless card (all different brands) and the problem still exists. I have tried using latest drivers from manufacturers website, drivers from windows update, tried switching the card to the other PCI slot, tried a whole host of vista tweaks from the internet meant to stabilise wireless connections, but all to no avail. So I turn to the wise population of OCN to once again help me with a problem! I'm grateful for any suggestions as I'm getting extremely fed up!

One thing I haven't tried is hard wiring my rig to the router, but I only want to do that as a last resort, as the layout of my house means that router is on ground floor, and my room is on second floor, so I'd need a really long ethernet cable and it would be draped all down the stairs! But I'd much rather my wireless worked properly, as I know it should be able to! I have also tried tweaking torrent settings, basically dropping all connections to very low numbers, but same problem still occurs, and as I said earlier, also during online gaming.

Thanks in advance.

Wireless can work in mysterious ways sometimes...anyway I'm not sure what the problem is nor am I familiar with that router, but a few things come to mind. Sometimes when putting a lot of stress on a wireless router, it will crash the router, but I'm just throwing this out there, maybe the router is dropping you're connection because of the stress your computer is putting on the network.

However the opposite could be happening like you said, maybe the wireless card in your PC is "crashing" which would explain why you have to restart. Try downloading a torrent on another PC and see if the same thing happens to them. And is it only on torrents? Or on anything that uses a lot of bandwidth, like a large download?

Wireless isn't one of my strong points so I'm just trying to throw out some troubleshooting tips for you.

it could be possible he set something up against your computer thats hes not telling you about? i cant see anything else that would cause this inconsistency, i know on heavy load wireless will crap out on some routers, perhaps your using a B adapter? did you try getting his exact wireless card? or you may be on G and hes on B, some routers get really inconsistent with multiple modes

Does your wireless card have an antenna on it? Iv used home made parabolic antenna's made from folders and foil and they gave about a 40% boost in signal strength. Here is a video of one.

. Just position it facing where the wireless router is and see if it helps. Make sure you use a blueprint though. Im pretty sure that the parabola needs to be fairly precise.

Are you the furthest from the wrouter?

Do you have any packet loss if you ping the gateway?

Thanks for the replies. To answer questions:

- Torrents run on my housemates computer, and downloads seem to work fine on mine, it appears to be upload (guessing) that crashes my wireless card. The problem also occurs when playing online games that transmit lots of data.

- We both have G cards, and he knows f-all about computers so never touches settings or anything like that, he runs with just the standard settings from me installing his card.

- I'll give that aerial mod a go at some point, but I get a good wireless strength, 4 out of 5 bars on the vista strength wotsit.

- I am the furthest from the router yes, but my PS3 is right next to my PC and has no probs. No packet loss when pinging the router.

Full signal strength doesn't always mean a great connection...as stupid as that sounds.

What's the environment? Is your pc under a desk? Is the PS3 on top of the desk? What form of encryption are you using?

PC is under my desk, and therefore closer to router than the PS3 which is on top of the desk. Using WPA-PSK encryption on the network. How can I determine the connection strength if the wireless signal isn't a good indicator?

Packet loss.

Lets start with the basics....

Have you tried changing the frequency channel?

i doubt its frequency since he has no problems with the other devices, its probably some random isolated problem on his pc, either hes closer to the phone or some device is giving of interfering frequency, he could have a problem with his overclock and the pci bus, its probably isolated
