Hmm.. seems I'm having the same issue with 2.08TM. After I installed the firmware yesterday, I found this morning devices are able to connect but not identified (ie no dynamic IP given). No internet access.

I reverted back to 2.07TM but the same issue remained. I'm getting around that thru static IP (on the device). Maybe I hard-reset the 850L and see if it resolves the issue. Will revert on the findings later.

Managed to resolve the dynamic IP issue with a factory reset. Seems factory reseting the router cleared it of whatever's causing the problems on my end. Router is still at 2.07TM. Likely keep it at this FW until someone can verify 2.08TM is good to upgrade.

I saw that in D-link global, the recent 2.08 (non-TM) has an update date in Feb/Mar.
