My wireless network connection seems to drop at random. Sometimes it runs connected for 12 hours straight. Other times runs 5 minutes and drops me. When it fails my laptop network card hangs and I have to reboot to re-establish connection. Why? The router is a 2wire model 3800 hgv-b gateway (at&t provided) with current software 22.214.171.124. My laptop network card is an intel pro/wireless model 3945abg with driver version 126.96.36.199 from April 2007. Thanks!
