I am having trouble making a stable b/g/n 2.4Ghz AP for laptops, tablets, etc in my building. The main issue is I have some laptops with an Intel Dual Band Wireless-AC 7260 card that will repeatedly disconnect for a couple seconds and the reconnect at different short intervals. The log on my MT shows simply shows the laptops as "attempts to associate" during this period. I do not see any disconnects on the log. I have found that running the AP in 802.11 N mode only gives me a stable connection but I need to have backwards compatibility with b/g too. The issue only occurs with b/g/n mode or b/g mode.
I have a RB433GL with an R52Hn card with two 4dbi antennas. I have found that using the same config on a RB951G-2HnD works as expected with no unexpected drops. The only difference I can see is that the RB851G-2HnD has a newer wireless chip. I have tried changing just about every setting and I am currently back to defaults. I am still in the testing phase so if there is a different recommendation for what I am trying to do I can go with that.
Any advice would be greatly appreciated.
