I put this in bugs also, but it may get lost there. Smart Connect always connects to Channel 1, which is where at least 6 of my neighbors are. As a result, I cannot get a stabl;e connection in my bedroom, which is at the front of the house and closer to the neighbors.
Why did D-Link make it so that you cannot pick the channel if Smart Connect is on?
If I manually set the G band to channel 6, everything works, but all the nice features of smart connect are lost. This seems like an urgent issue to me.
There is also a close neighbor on Channel 6. Channels 8 and 9 are free, but the support person said that the DIR-890L works best on 1, 6, 11. There are a bunch of people on channel 11 too. Why do all the router manufacturers optimize operation for the same channels?
