I have recently begun experiencing speed issues. I am meant to be on 200mb and according to tech support should be receiving around 230mb, however on wifi. I do not receive anymore than 50mb regardless of 2.4GHz or 5GHz and that's on a very quiet channel. I also made sure that the hub is in the open space near no microwave or baby monitor or any other electrical device that would interfere. the test starts around 60mb then goes down to between 30-50 max. upload speed ~13mb and ping ~13ms were mostly unaffected. I ran a speed test wired and only managed to get around 100mb. my network card supports up to 1Gbps. I then changed the settings into modem mode and only manage to achieve around 140mb max (still a long way to 200mb). when I ran my test, I made sure no other devices was connected so the speed test results would have not been impacted. this has affecting my youtube streaming, downloading and even browsing. Restoring to factory settings, and all the other tricks that you can find by googling did not help either. the other night, my upload speed was even faster than my download speed!??!!!??!?! Could my router have developed into some technical difficulties? last time I had an issue with it, technician came out, adjusted the power levels from the cabinet and put a 6dB attenuator at the back of my hub. The time before that I was given a new hub and 2 attenuator on top of each other which the previous engineer just took them off.
Any help is appreciated before this internet speed drives me crazy.
