Getting randomly disconnected from the internet

[varzock]

Hi everyone,

This is the first time I write in these forums since I couldn't find help from anywhere else to my problem.

So here it goes: I have an ASRock K7S41GX motherboard in my Antec Aria case. It has integrated network card but I have it disabled and I'm using my own network card to connect on the internet.

The problem is that the connection gets randomly dropped every now and then and when I try to re-connect Windows complains that the username and password I'm using to join the domain are invalid. I'm confused. I haven't joined any domain, ever. And the username and password haven't been changed at all.

This goes on for about 10-15 minutes and sometimes it connects itself back right away.

I've tired using my integrated network card when connecting the internet too, but it has the same problems.

I'm really lost with this and it's starting to piss me off :| I've called my internet service provider and they've told me everything fine at their end.

All this started happening when I changed my motherboard... so the problem is most likely in it but what could I do to solve the problem?

not enough info man...

i'd say its a comcast/dsl issue, like the modem...etc....but have no clue cause you don't give enough info...have you tried a 2nd computer? have you tried your system on someone else's connections?

Ok sorry, here's some more detailed info:
ASRock K7S41GX motherboard
512Mb memory
Asus Radeon 9200 Pro
2 x 120Gb HDs
Realtek RTL8139 PCI Fast Ethernet NIC

I really, really hope someone could solve this problem or atleast give me some hints. I'm getting pretty desperate with this

Everything worked just fine with my other motherboard. It did never disconnect like this but I wouldn't like to go and buy a new motherboard without first trying to fix the problem.

Severe fragmentation maybe.

Get DRTCP from Broadbandreports.com and see if your MTU and RWIn settings are way off.

Thanks for replies. Downloaded DRTCP, tried it, changed MTU and RWIn sized like it said in the help file. Rebooted. Prayed. Waited. And still.. the same problem occurs :frown: this is getting weird

Ok here's an update: as I told in my previous reply, I changed the setting of MTU and RWIn (changed them to bigger value) and now when the connection drops, it will connect normally, but still the web pages won't load nor I can join any IRC channel. This takes longer now. Then it gets back to normal after awhile. Connects to IRC channels, loads web pages etc...

but so far it hasn't told me about wrong domain or wrong username / password


maybe this info helps a bit locating the source of the problem?

Anyone? Any clue?
