Hardware version 1.20, firmware version 1.0.9. We have two of them connected to an ER605 v2, and we also have a third EAP-245 that has no issues.

The access point seems to lag on a regular basis. By lag, I mean the internet connection on any client connected practically cuts out e.g. movies buffer, Google searches stop loading, emails won't refresh, etc..

This happens for up to a minute usually, and then everything resumes as normal until anywhere from a few minutes to an hour later it happens again.

Client number is irrelevant, it happens with 3 clients or 20 clients,

Channel usage hovers around 12% in 2.4Ghz range, and 2% in 5Ghz range.

Cpu never rises above 50% (usually hovers under 10), memory stays below 80%.

Dropped frames, rx errors, etc. seem nominal.

No QoS settings enabled at all.

Issue DOES seem to affect LAN connections as well,

Not sure what other info I can offer, but ask away and I can try to get it for you. Our EAP-245 has no issues whatsoever
