I have been using RT-N56U for almost two years now.8 months ago i upgraded my internet line up-to 30 meg.I received virgin media super hub (modem with integrated router).i put superhub to modem mode and used RT-N56U as my router.ever since i upgraded to 30meg line internet was super slow .recently i bought a WD my book live and connected it directly via wire to N56U. when i started transferring files i realized the transfer speed is only around 1.5MBps.i was confused because since my book live was connected directly to the router i was expecting bit more. as result i took virgin media super hub out of the modem mode and activated wireless router. not only my internet reached 30meg when i connected my book live(via wire) transfer speed reached 5.5 Mbps. I connected RT-N56U as an access point and did speed tests simultaneously and Asus only reached 1.5Meg maximum while virgin superhub reached almost 30meg. I did a hard reset to asus router and upgraded to latest firmware. (3.00.43.42). Is my router dying out?
