Factory reset as in load stock firmware? I am using Asus Merlin firmware.ATT may have changed something on their side. Factory reset and manually configure to test .
Router has been on Merlin for quite a while now; over a year. Updated to latest version about a month ago - Current Version : 3006.102.5. Buffering just started a few days ago. I had it setup thru ATT router using IP Passthrough. I turned it off and reverted back to ATT router; just reconnected the Asus router this evening using a different SSID; so far so good - no buffering.Hi,
Others might be better placed to help, but perhaps you could provide the Merlin FW version, try to post (with personal info redacted) debug logs and confirm you did a hard reset after moving between stock and Merlin i.e. after the Merlin install you did a hard reset and entered everything by hand?
Merlin still reccommends a hard reset moving between Stock and Merlin FW and that it is usually not necessary from Merlin to Merlin unless specifically stated in the release.
I'm not sure the SSID makes any difference, but maybe you connected to one called "NoBuffering" now vs the previous one which was called "BufferLikeCrazy" and it really took it to heart. Glad it worked out for youjust reconnected the Asus router this evening using a different SSID
