OK, so I managed to get a speed straight from the hub which seemed to be full speed (200mb/s+). Wi-fi speeds are around 10-17mb/s and my Powerline adaptor speeds (my house isn't cabled for ethernet) are even slower (around 10mb/s). Should these speeds not be faster, especially Powerline ? I did try to set the hub back to router mode to test speeds in different places and for different hardware but couldn't get any wifi from it.
The adapters are tp-link. My latest tests are that everything works fine using the hub as router. 2.5GHz speeds are pretty slow away from the router but that is presumably due to brick walls etc. in the way. Ethernet speeds through powerline adaptors are still slow, maybe my electrical mains cabling is not good ?
With the hub in router mode everything seems slowed to a crawl. All wi-fi is slow and ethernet is slow even directly connected to the tp-link router so perhaps a router issue if the hub is not slowing down in modem mode.
Doing some more reading on the forum and elsewhere this seems to be a common and ongoing problem for a number of years with this hub.
Thank you for reaching back out and for the update, I was able to locate you on our system with the details we have for you and it looks like you have now put our Router min Router mode, have you now removed your 3rd party Router?
Yes, I have. Having read many posts on this issue spanning a number of years it is clearly a Hub 3 problem which has never been resolved. I have given up trying to sort the problem and will be moving to Community Fibre as their hardware is hopefully better and speeds are much higher for the price.
The cabled speed in both modes through my powerline adaptors is very low, around 10-15 mbps. I have now also tested the speed through my router when connected to the hub in router mode and it's low speed again. This is quite confusing as I am getting similar low cabled speed through my router with the hub in either mode but also through the hub and powerline adaptors without my router. Only direct cable to the router mode hub gives full speed.
