My new Asus RT-N56U just arrived got it configured and its speedy all the time both wireless and wired! Happy days, quite funny I get more speed wireless as Dell only put a 100mbit nic in.
Got a different IP again with the new router
Still seems the SHUB is stuck on using channel 4 & 5 on US instead of the 1 & 2 I got moved on to previously.
Happy with this router and for me didn't need to get the n66 as don't have the need for it and next upgrade will be to 802.11ac.
Forgot just need the 120mbit to be rolled out now hopefully the September date is true unfortunately it will probably be neared the end than the start of the month.
