Just installed a new E3000 running v1.28.9054 MIPSR2-beta E3000 USB Ext, connected to a U-Verse 3801HGV box.
Here's the problem. Everything works, except, if I access the 3801HGV at 192.168.1.254. Usually but not always the web page will load. If I then click on any of the links in the homepage, sometimes the page will load and sometimes not. If it doesn't load, then a few minutes later the TV signal might go off for minutes. Typically the internet connection does not go off.
The E3000 replaced a WRT54GS. I manually copied over all the config settings from the WRT54GS to the E3000. There were no problems accessing the 3801HGV from the WRT54GS, ever. Maybe I could try a different Tomato firmware variant on the E3000, but which?
