Possible fix on HH5B re dropping wifi on 5ghz and fast on 2.4ghz.
As we all can see the HH6 is having problems and going back to the HH5 is being used by a few customers.
However splitting the 5ghz and 2.4 ghz with a different ssid ie add 5 ghz to the 5 ghz will work.
But disable smart hub use a wifi scanner app on a phone and look for a clearish channel for both 2.4 ghz and 5ghz.
Then via the Hub router log in and use 802.11 bgn at 144mbs for 2.4ghz and then 802.11 an on 217 mbs for 5 ghz.
The above works and i have had no drop outs and at 51 mbs download and 9.5 on upload for the last few days.
I have also asked to be removed from the FON/wifi x set up as this was causing more wifi channels to log in to.
Today i have used the smart wifi app and can see the FON and wifi x has been removed.
So not sure if this will help others but seems to be a workaround for me and both 2.5 ghz and 5 ghz are working well today and yesterday.
Just done a few more wire less speed tests and more or less the same 51/9.
I am 150 m from cabinet and 0.6 km from exchange.
I also am using the open reach modem ECI as this is better on wires and lay out.
Hope the above helps others out.
Will monitor over the next few days and weeks.
Forgot to say the modem is in a cooler place near a vent brick and is wall mounted with 4 rubber extensions on the base to give another 2 cm of air to help cool the router.
