People have got to know about this problem because it's being discussed on many laptop forums. Seems that there is a problem with Intel 3945ABG laptop network cards communicating with certain Linksys routers. I should know. I have the WRT54GX4 SRX400 router. I just bought a Lenovo dual-core notebook with an Intel 3945ABG wireless card. The notebook will not connect to the Internet. When it does, it throws all my other laptops off the wireless network -and- my wired desktop off the Internet. At first I thought I had a defective laptop. From reading a large handful of posts on Internet forums, it seems that there is a huge compatability problem amongst people who have laptops with that Intel card + a Linksys router. I just updated my firmware to release 1.00.15 but that doesn't solve the problem. Is Linksys aware of this problem? Is there a fix available? Thank You!
