My friend has a Dell Inspiron laptop running Windows XP. He has recently
found that he is unable to connect to his home wireless network. He receives
the error message that there is "limited or no connectivity", but at the same
time the signal strength is reported as good, and when he goes into the "View
Wireless Connections" window, it reports that he is connected to his wireless
network. But he is unable to connect to the internet or Skype. I don't
understand how the computer can be reporting limited connectivity and good
signal strength + connection to network simultaneously.
It is definitely not a problem with the router as other laptops in his house
are able to connect to the router and to the internet without difficulty.
In order to try and resolve the problem we performed a system restore back
to a date last week when he thought everything had been functioning normally.
This did not resolve the problem, but at this point I noticed that the
wireless network connection icon had disappeared from his taskbar (it had
definitely been there before), and that a red security centre icon was in the
taskbar, reporting that no virus protection could be detected. (I am not
certain whether or not this had been there before). He had previously been
running Windows' own virus protection, but now Windows cannot even detect its
own anti virus software.
I think the next step must be to reinstall some virus protection but I
wonder if anyone else could offer us some advice....
o Is it likely that the original wireless network connection problems could
have been caused by a virus, which has now also disabled Windows' antivirus
software?
o If so, are there any particular viruses that are likely culprits? (If we
could identify these I might be able to download removal tools on my internet
connection that he could then try).
o If it is unlikely that the networking problem was caused by a virus, what
are other likely causes and solutions?
Many thanks in advance.
