I i beleive i have a virus, I have tow computers wireless netoworking both running windows xp, mine is the lead computer, i usually get alot of email for bussiness and i use outlook express, Well the other day i booted up both computers but for some reason my computer (the lead) cannot get online or recieve any emails while my wifes computer the one networked to mine can get emails and surf the web, the problme im having is i went and bought norton but its not up to date and gives me nothing

and i cant get online to update it? i have also tryed the cleaner a trojan remover but again i cant get online to update it so if its somthing new it wont fix it, and i also cannot sen any info between my wifes or my computer it has completey isolated me.other than that i can go into folders and install things but i cant seem to fix it. any help would be greatly apreciated thanks,
p.s i also tryed system restore it wont let me restore my system at all,

 

Ok, information we need:


1. What was the last thing you did, or installed before it went down?
2. What kind of internet access (DSL or cable)?
3. What is your IP address, and default gateway (start-run, ipconfig /all)
4. What is the model of the wireless NIC and router/AP?

 

just answering emails nothing dled or installed, i shutdown that night and when i turned it on in the morning i couldnt get online, im on comcast cable, the wirless is a linksys 2.4ghz 54g
its the latest card the 10.112 g or somthing i ran the ip config and the screen pops up and disappears real quick,

 

Run cmd and then the ipconfig command.

 

ok i ran ipconfig heres what i got, for the actual wireless for the ip and gate way i got just zeros above that its says media state disconnected? the under that it has ethernet adapter network bridge
the ip is 192.168.0.1 the subnet mask is 255.255.255.0
and the default gate way has nothing im guessing this is not good news? it may not be a virus i guess i dont know what i could have done to cause all this? thanks for all the help guys!

 

Delete the bridge in Network Connections.


Does the wireless NIC still show media disconnected when you do an ipconfig /all?



::sorry about the start-run thing. Typed this as I was running out the door. I meant to stay, start-run, cmd, ipconfig /all

 

if you're running windows xp, the hardware sharing the connection MUST have the ip address of 192.168.0.1 or windows xp will give you trouble.

 

okay did ip config all, it still says meda disconnected,
under ethernet adapter wirelss connection al for the ip and gateway i get nothing then under etherner ada[ter networks i get 192.168.0.1 as the ip and i get nothing for the gateway, above all this there was a couple things one being ip routing enabled and it says no
also win proxy enabled it says no?
i had a guy install this wireless netowrk so i have no idea about what this means ,umm hope this helps, and if i delete the bridge will the other computer networked to this one that can still get on the internet be able to? thanks for all the help guys,

 

Ok, right click the wireless connection, and choose View available wireless networks.


Does it show your SSID?


Try to connect if so.

 

yes it does its linksys or somthing like that so i clicked connect like you said nothing happened ,no internet and no email, its very wierd that im the lead computer and the other computer can still get online? again man thanks for all the help,

 

Do you know much about changing channels on the router?


I can kind of guide you, but if you aren't familiar with this, it may not be the best idea.

Unless you are game, of course

 

lol, count me in ,im not a compltete idiot with the hardware but definetly not as advanced as you so kind of humor me with the directions, i just have 2 questions aswell this is starting to not look like a virus? and is it possible i could screw somthing up to were the only computer i can get online will not be able to ? if not then go ahead and list the instrcutions and whats supposed to happen, greatly apreciate the help man,

 

Ok.


Open up your router config (on wife's computer).


Open IE, put 192.168.1.1 in the address bar.


Admin is default password.


No username.


Click ok


On the first tab, you will see the channel settings at the bottom.

What channel is it currently on?

 

No, this doesn't look to be a virus as of yet.

Yes, you could lose access to the only computer you have online. Thats why I am just asking for info first


But I've noticed that you have an ethernet card too, so I am assuming you can hook that to the router and revert the settings.

Correct?

 

Should this be 192.168.0.1 for the router?
Or am I confused -AGAIN.

Does your MB have Firewire? Reinstalling or updating Firewire (MB) drivers can make Win XP think Firewire is your network.

 

Linksys uses 192.168.1.1 by default.

Dlin k uses 192.168.0.1 by default.

Its whatever your default gateway is. The above post had no D.G., so I am guessing that the ethernet card is static.

IEEE 1394 is a legit network device for XP. It will always show up in Network Connections, because it can be used as such
