problem: i can't acces internet after 15 minutes or so(sometimes more or less) untill i reboot..then it works foe another 15 min


i havent installed any new drivers for my nic card.. i have a yukon 88E8001 card, i havent changed aanything i can remeber for this to happen. and i do NOT have any p2p programs installed, i connect to the internet trough comcast, and computer is hooked up to router trough cable. and i know it's something wrong in my computer because i have a pocket pc that goes online without problems wirelessly

this is what ive tried so far:

1. follwed the steps on the hijiack this log section. computer apears malware free(didn;t post a hijack this log though cause i don;t know if this is a malware issue)
2. renewd ip after it went offline
3. hit repar on network connections properties on conmtrol panel
4. turn off windows firewall
5. reset router (wrt54gs latest firmware v4.70.6) and cable modem ( motorola surfboard)
6. log off/ log on windows sesion

thanks :tazz:

try a different cat5 cable
try a different nic card (if possible)

While connected
start > run
cmd
<enter>
type
ipconfig /all
write down ip address, gateway, dns servers

when you are disconnected, can you

start > run,type
cmd
<enter>

ping yout local host
ping 127.0.0.1

ping your gateway
ping (whatever your gateway address is)

ping your name server
ping (whatever a dns server is)

what are the results

that's with a bad connection?

It looks like all is working properly--

puzzled.

do you notice any activity on the cable modem lights while this occurs (flashing)

I wonder if you might perhaps be

a) getting hammered by a port scanner
b) have a malware infection that is consuming your bandwith

have you checked for malware?

yes i have a flashing light on my modem the one that indicates pc activity..both when i do and when i don;t have internet on my comp it flashes.

i followed the steps outlined on the "hijack this logs start here" and i seem to have no malware. i also ran nod32 and the panda antivirus online scan. and it came out clean.

i suppose i should post a hijack this log? :tazz:

i have also cheked the windows event viewer and there i nothing at the time it goes ofline...there is ocasionally a

IPSec Services: IPSec Services failed to get the complete list of network interfaces on the machine. This can be a potential security hazard to the machine since some of the network interfaces may not get the protection as desired by the applied IPSec filters. Please run IPSec monitor snap-in to further diagnose the problem.


in case it's relevant, i have vonage VOIP service..but it has never sucked a noticeable amount of bandwith.

thanks!
