Hi there. I have an acer wireless notebook with centrino tech., a Intel Pro Wireless 2200BG(802.11b/g WlLAN). I have a router and a wireless setup that I am sure you've never heard of (since I live in Germany) and I definitely do NOT know alot about computers. Anyhow, after spending days and DAYS, I was finally able to get my notebook connected to the internet and it worked wonderfully for a couple of weeks. (Using windows to connect never worked, so I used the Intell to connect). That is, I was never able to plug and play with this thing. While I was having trouble connecting the first time, my husband took it to work and it worked fine and a friend took it home and there it worked fine as well. On the weekend, I tried to connect again and I found that I cannot anymore. I have discontinued my virus software, actually now I have recovered my whole system out of shear desperation and I have disconnected the firewall on my router. I do not have the WEP enabled. I have also disabled windows and I am trying to use the Intel software to connect. Currently, it cannot find anything. (Interestingly enough, sitting right next to my notebook is a Sony notebook and it connects ((though right now it is turned off)) to the internet using windows just dandy!!) My notebook is not connected to a network but I do have a PC connected in the same room. I have no mobile phones around, nor any blue tooth tech. turned on. I have tried to download current firmware for my router, but truthfully I am having trouble using the winzip and now each time my firmware exe. file turns into a word. doc! I have also tried to repair/deinstall and reinstall the Intel drivers, but that doesn't seem to do anything this time. I have used command to try to ping the router, but all the packets get lost. I apologize if I sound totally inconherent, this is really getting on my nerves. I was so proud for "fixing" the problem myself the first time and now this. Yikes! Amy P.S.: Okay, I see that you have t-online products in the US now, my router is a t-sinus 130 dsl, if you can place that product.
