Im not sure what the probem is. I am using a USB stick that has prepaid data on it. It was fine till about 2 days ago when the lag just didnt stop when im playing online games. Ive changed my DNS to googles 126.96.36.199 and 188.8.131.52. Nothing has changed. Has optus got problems or is it on my end?
Doesn't sound good - have you checked here for any listed network impacts that may be causing this?
Everything is back to normal now.
I did check that link when the issue was present and there was nothing relevant under the outages tab. What was interesting was that for as long as the issue persisted, under the coverage tab the 4G+ coverage was overstated for WA, even more than clicking the 6 months future coverage. Possibly coincidence but if it happens again I'll screenshot it.
