Network wifi slowing while main computer is on

post #1 of 7
Thread Starter 
Recently while my computer is on and my wife is trying to stream shows or movies to our ps3 it will stutter and eventually freeze. I've been playing diablo 3 but that isn't the issue because regardless of diablo 3 or not just the fact my computer is on it slows it down.
Is this a computer or operating system problem or should I look into getting a new wireless router(currently using a linksys wrt540v2).
Any help will be appreciated Because she wants to watch her shows and I need to play diablo!

Two things come to mind first...

a) bit torrent

Ensure bit torrent files aren't actively downloading/uploading. This can cause severe hit on your bandwidth and network speeds

b) virus

Viruses can cause endless issues, one of which is impacting network activity

Utorrent is definately not running. Any virus scans you recommend MSE comes up with nothing. Also, I did a fresh install about a week ago so a virus seems less likely.

Hmm, well I was using Norton 360 for a while, but just switched to MSE myself.

Perhaps try rebooting the router/modem by unplugging for at least 10 seconds and then plugging back in.

This is going to be a long post, but bear with me. If you're not a "network guy" and the terms I'm using don't compute, just ask for clarification.

The WAN/Internet interface dupex on your router (preferably router and modem) should be "full". The speed and duplex should be running at 100/Full for most, if not all, of the router's interfaces. 9.99999 times out of 10, half-duplex is bad. A bad cable can cause a link to operate at half-duplex. Check your cable(s).

Your computer and PS3 don't have the same IP address, do they? Windows (assuming you're using that) will usually alert you to this. If they are sharing the same address, then half of the traffic destined for the PS3 is going to the PC and vice versa.

Assuming you only have one LAN subnet, the subnet mask should be the same for all devices on your LAN. DHCP should handle that if you're using it, though.

Is the PC or PS3 using a directed broadcast address? It's a rare scenario, but some devices/OSes allow that. An example of a directed broadcast address would be 192.168.0.255 if your gateway's IP is 192.168.0.1 255.255.255.0. Another example would be 192.168.0.31 if the gateway's IP is 192.168.0.1 255.255.255.224. If this is the case, then traffic destined to an IP like those listed will go to every host on that subnet. A good router shouldn't NAT for a directed broadcast, but you never know with consumer-grade stuff...

Is the PC running any kind of backups in the background either to the "cloud" or to a local storage device?

Is Windows Update pulling down any updates in the background?



Bottom line, there are lots of "little" reasons why this problem can occur, and it's hard to address (or think of) all of them or the possible combinations of all of them. A packet capture would probably help a lot.

Thanks for the advice! I figured out the problem last night actually. So I googled "slow ps3 wifi" and was reading people complaining about it having 801g or whatever and how that is a common frequency and sometimes even microwaves cause interference.
So I was thinking about what may be causing interference and my wife asked if it was because I was using "two monitors".
She was half right because last week I bought a catleap yamakasi and apparently because he router was underneath it, it was blocking the signal. I read through the ocn thread on that monitor and noone complained of that issue but there u have it.
Moved the router to the adjacent desk and wham bam problem solved.
Thanks again for the advice but the problem was more mundane that I would've expected.
