So I've had the 88U since April. This past weekend, I enabled the port bonded to create a LAG which connected to a Netgear Prosafe Plus managed switch that also has LAG capabilities. I then connected a device to the Netgear switch. Well, the router did some very weird things afterwards...
To start, the admin web interface became very slow. Anything that I clicked on took 3 times longer to load up. When I disabled it, it went back to normal times.
Wireless, both 2.4 and 5 ghz spectrum, became very flaky. After re configuring my SSID's and passwords, devices on my network including my android phone, Nest and PS4 had trouble connecting. Sometimes, I'd receive a message saying the WPS password was wrong even though I knew it wasn't. At other times, it simply would't connect to either. I had better luck with 5 ghz as the PS4 would not connect at all. All this time, each connection attempt seemed to take a lot longer than normal times.
I tried reconfiguring the SSID's and passwords, encryption type, etc. which never really seemed to help.
After resetting to factory default and disabling the LAG, everything to started working. All of my devices seemed to have a much easier and faster time even attempting to connect. The Nest I had to keep on the 2.4 ghz instead of where it was previously connected to 5.0 ghz. I haven't figured that one out yet. I had the least trouble with my android phone. My laptop running Win 7 also didn't seem to have a lot of problems. I did run a constant ping to the router's interface IP and every so often I'd get a very late response. Connecting the PS4 just started working as well. But the router itself just seemed to grind to a halt with LAG enabled.
In general, the LAG shouldn't have affected wifi connectivity but perhaps it's affects on the router as a whole caused the issues I had. Has anyone had any experience with the LAG bonded ports features?
Edit: I'm running the latest Asus firmware. I'm not home right now so I can't give you the version. I intend to try Merlin's as soon as I have time.
