I have a T530 running Win7 Pro with an Intel Centrino Ultimate-N 6300 AGN wifi card.
I just got a Quantum Gateway router and the computer is having big problems with the 5GHz band. It will connect, but has horrible speeds -- around 0.1 Mb/s (not a typo). When I connect to the Quantum on the 2.4 GHz band everything appears to work fine.
The computer has normal speed when it connects to other 5 GHz APs. And all my iThings have normal speeds when connecting to the Quantum at 5 GHz. Any idea what could be going on?
