OK, I was finally able to test this in two different computers - same exact behavior. In IE (8 or 9) and even through my Smartphone, the interfact get stuck and does not show, for example, wireless clients that are currently connected (Status, Wireless).
Also, if I am logged in through Firefox and it works fine, if I log in through IE simultaneously the Firefox session freezes as well.

Turn off Short GI under Advanced/Adv. Wireless.

Ensure DNS IP addresses are being filled in under Setup/Internet/Manual? You can copy and paste these from under Status/Device Info/Wan section.
They are filled
Turn off ALL QoS (DIR only) GameFuel (DGL only and if ON.) options.
I am hesitant to do that. I need QOS for my work VoIP...I have one rule setup which is RTP
Turn off Advanced DNS Services if you have this option under Setup/Internet/Manual.
Did that, and as soon as I unchecked it, the DNS numbers that were filled before got deleted. I added them manually. Still no change though.
Turn on DNS Relay under Setup/Networking.
Already on
Setup DHCP reserved IP addresses for all devices on the router.
Already done.
Ensure devices are set to auto obtain an IP address.
Already done.
I don't see how all these things could be related to the fact that it refuses to work with IE, only with Firefox...
