Sorry to rekindle this post; thought it better to do this rather than start a whole new one, again...!
We've 350Mbps broadband; faultless on Ethernet, but wifi (5Ghz) we're lucky to see 50Mbps+ and 2.4Ghz is about as useless as using a colander to catch water...!
I've reset the SH3, no change...
I'm about to pull the plug on a TP Link sent of Mesh repeaters, but having a SH3 that works would be a lot simpler and TBH; I'm paying for that, so why should I have to fix it's unreliability myself and be out of pocket!
TBH I don't want to 'call technical support' as they're painful at the best of times and they do NOT listen... I'm fairly tech savvy, so just need them to listen to the issues and help from there, not go round & round in circles...!
Any thoughts/latest advice re this before I look to escalate it
Cheers 👍🏼
