My home wireless broadband upload speed is totally zero/no upload at all though the download speed is quite good. Tested with TPG speed test and Ookla speedtest on mobile and computer both with 2.4GHz and 5GHz. Band steering is disabled. It all started happenning since last 3/4 days and before that it was performing well.Have checked the signal strength, showing -92dbm to -96dbm which should be quite good for 4G signals I believe.
