Hope someone can help. I have just installed a complete Belkin wireless network in our house which consists of : ADSL modem with built in 802.11g router F5D7630-4A Wireless desktop Network Card F5D7000 Wireless Notebook Network Card F5D7010uk Main unit and laptop are both running windows XP Pro with the main unit having SP2 installed. Both have Norton's antivirus I have the following problem though. Network works fine with WEP disabled, can see other computer, connect to internet etc but when I enable WEP it all goes Pete Tong! This is how I've been doing it so far, with a few variations. Access router via web page and enable WEP. Selected 64 bit WEP and have inputted the passphrase which then generates a key in HEX. Applied changes and then I loose comms with router...seems fair enough as I haven't enabled the WEP on this PC. Double clicked on Belkin icon in bottom right of desktop and selected advance. Removed preferred network and re-configured available network with WEP key, by doing the following: Data encryption ticked, network key inputted in normal text with key format ASCII characters selected, key provided for me automatically de-selected, then clicked ok and apply. Still no access to router or internet. What am I doing wrong? It must be something really simple as everyone else can do it aprt from me, or is it an age thing (late 30's!!). I have tried inputting the network key in hex form, well, I call it hex anyway. I just copied the hex code and put it straight in without any gaps between the pairs. Is that the right way? I had changed the key format to take account of this to no avail. The only way that I could get it all to work again was to reset the router and start all over again....which I'm getting quite good at!! I'm hoping that someone out there can show me the error of my ways so that I can have at least some form of security! Cheers all PS: Have tried the above on the laptop and have the same result. I did read that for WPA to work I would have to download some software, but surely not for WEP?
