Webuser Forums: I'm having problems with my wireless

I have a LiveBox. My PC is connected to it via a cabel and I use the wireless for this laptop. At least once a day no data seems to get in or out of the LiveBox, out of random. I'm connected to it just fine but I have no internet access at all, as does the PC. Another problem that recently started to occure, odly enough after I found and removed a virus, is that sometimes i'd randomly get an exclamation mark over my wireless icon. I usually have to restart the laptop to get it working again. Additionally, when I right click > Repair the icon it stalls at "Renewing IP address" which is later followed by the exclamation mark. Normally any re-connecting to the LiveBox after I got kicked off would give me no errors but now I just get the "!".

Thanks.
