wifi problem

panyan · 14 Sep 2011 at 18:59

i have a netgear dgn2200 router and my mothers computer has an edimax wireless n pcie adapter

i connect to the network and everything is fine, good signal strength, good connection, etc

but when i go to load a webpage it never loads, when windows try to download updates it can never download

ive rebooted the computer and the router, checked it is getting a valid IP, checked the router has internet access etc etc

i am at my wits end! what is up with this wifi!? :confused:

Have you checked your virus checker?

yep, no viruses

Do your other computers connect to the internet on the same wifi?

i have one other computer (this one) connected via ethernet and it is perfectly fine on the internet and has a similar IP

Have you tried pinging a server to see if it connects?

yes, i tried google.co.uk and it timedout

Sorry, I should have explained better.

Some virus checkers have agressive firewalls that can interfere badly with internet connections. They're always worth checking. Another thing is Norton, for example, doesn't react well to being uninstalled (there's a special tool to do it properly) and will lock down various functions of your PC if you don't do it the right way. It might be worth (briefly) turning off your virus checker completely to eliminate that as the cause.

Have you tried that computer wirelessly or just wired?

How about trying other browsers?

I'm using avast that I have on all my machines and I always recommend it, I've never had an issue with it

I always avoid Norton, it is worse then no antivirus!

anyway, the computer has been fine fir the past months on the wireless, it is just the past two days

yeah, all browsers, it can't even ping google :confused:

Try ping 8.8.8.8

Try doing an nslookup www.google.co.uk

Could well be a DNS problem

What OS? If it's win vista and sometimes win 7 and router uses WEP protection this can cause an issue. Change to WPA-PSK set new name and PW and try that see if it works

on w7 and wpa2

Silly question but network and sharing centre isn't saying that it's connected with limited acces or anything cos then it's an IP address issue

nope, it has a valid ip on the network and to the outside world, it isnt that

panyan · 15 Sep 2011 at 22:59

seandog said:
Just seen that IP address, is ur ISP sky?

nope, im with orange broadband, have been for over 5 years

this issue is very odd because sometimes the internet is fine, other times it is so slow it is unusable :confused:

panyan · 15 Sep 2011 at 23:13

seandog said:
When the connection is slow have you ever ran a netstat check in cmd prompt to see how many open connections there are?

nope, how would i do that?

panyan · 15 Sep 2011 at 23:24

seandog said:
Just open command prompt and type netstat

Count the connections it shows, generally over 10 will cause issues and could be signs of virus

i will do, but there is no virus on it, it is a recent install with avast and comodo fully updated - and ive scanned it numerous times etc

Certainly is a head scratcher indeed, best thing to do after checking all this with no success would be to have a different laptop and side by side when it starts to go iffy and check that ones status, if both show issues then it's the wifi/ISP but if one is fine and other is borked then it's computer issue (somewhere)

well i have this computer wired up to the same router and network and i never experience any of these issues! :confused:

have tried changing the wireless channel?
you said its only happened recently so maybe some in you area got new wireless which is affecting yours?

seandog said:
So it's wireless then for sure, try cycling through the router channels and see if any of them resolve it, could also point to computers wireless

Back when I worked for a ISP tech support I rem something about FireWire driver crippling the wifi, check device manager and make sure there no driver issues there or the 1394 driver is being the culprit

ok, ive changed from channel 6 to 9

there are no 1394 drivers/ports on this board
