My Samsung tablet is slowl downloading. Just had fibre installed still the same. Speed check with tablet 25mbps download. Speed check with Huawei phone 100mbps all good. I suspect that the tablet is using the 2.5 Ghz frequency on the router to download and the phone is using the 5 KHz frequency on the router. I cannot find out how to check my tablet to check this. I am not a techi but do have some understanding.
