2wire 3801HGV can't obtain IP address
I had the old 2wire gateway 3801HGV (ver1.0 firmware 184.108.40.206-enh.tm hardware version 000778-004) I would like to replace the rental gateway 3801HGV (firmware 220.127.116.11-enh.tm). My gateway can sync the signal with ATT U-verse server but It can not obtain the IP address. I had DSL connected but I can not get internet connection. Is this problem due to the old firmware? How can I manually upgrade the firmware to 18.104.22.168 via my computer? How can my gateway register its Mac ID with ATT u-verse server? Thank you very much.
