@David-TP I'm using Optimum and was on 1.2.7.

@Riley_S it's a XE75 model mesh. Running 1.2.8 . been working fine for a month plus since firmware update. Just stopped. Since my original email, did a factory reset of router. Still get .02 upload...

I updated my firmware and now have zero upload speed. DL runs at 650mbps. Modem unable wifi running normal speeds. Tried all forum solutions but can get and upload speed. Swapped cables etc.
