Hello!

I have an ac66u router and have major problems. some pages won't load, because of for example pending state by loading a css file.
it's always the same, tried several firmwares, usb modem sticks and so on. some other pages are working fine!
I already tried custom firmware, without success.

By using the usb modem directly attached on my computer, everything works like a charm. HELP :/

thx in advance!

so long

ps: sorry for my bad english :/

update: with a stick without hilink (nat) it's working... but i need hilink because of the roaming feature :/
