I'm using a mir3g as a wireless client for an EAP network. I've been using snapshot r10348 for a while and there were no problems in this regard. But there are other fixes with mt76 and/or general openwrt commits so I updated to the latest snapshot.
After updating, I noticed my WWAN speeds slow down from 150 mbit/s to 30 mbit/s after about 30 minutes. This is even though link speed stays the same as shown on LUCi (around 300mbit/s).
Logs show this happens after an EAP reauth event accurs (which happens every 30 mins on this network):

any clues? or anybody having the same problem?
Thanks.
