I've noticed that recently my Wi-Fi speeds are slowly dropping over time. They should be 60mbit, but I start noticing them dropping so I run speed tests. I can watch them falling to 30mbit, then 20mbit, 10mbit, 5 mbit, and 1 or 2 mbit, by which point the internet is basically non functional. These speed drops take place over a number of days. My wired ethernet devices are fine however, and will still be getting 60mbit.
When I reset the router (a miserably bad Homehub 5), Wi-Fi speeds return to normal... for a while. After a few days, maybe a week at most, the cycle begins anew. This didn't used to be the case.
Is the hub defective? (a loaded question I realise). All but one of my devices are on 5ghz, and there are a lot of other access points in my area, so a good deal of Wi-Fi clutter.
I can keep restarting the router but I shouldn't have to. It should just work.
Make sure you turn off "smart setup" on the Homehub.
See link how to do that.
Some devices have a problem with the Homehub dual band having the same SSid (name). Try giving the 2.4Ghz and 5Ghz frequencies different SSids. Just add a 5 to the end of the 5Ghz SSid so you know which is which. Check the 5 GHz Sync with 2.4 GHz: is set to NO.
Once you have done that "forget" the connection on your device and then restart the device and log onto both the SSids if the device can use both frequencies. Not all devices can use 5GHz.
Try downloading and running the free version of inSSider. This will show you the wireless channels that your Homehub/router is transmitting on as well as the surrounding networks. You want to take a note of the channels in use and change your Homehub onto a channel that is not being used. If they are all being used try channel 13. It is not used by UK routers by default. Ignore any warning you get about using it.
See Link how to do that.

Splitting the 2.4 and 5ghz was the first thing I did when I got the router. I also turned Smart Set-up off long ago.
Sadly inSSIDer isn't free anymore, so I'll be skipping that one. I did grab something similar called NetSpot though, which showed me that my 2.4ghz was on channel 1 (as was some other Wi-Fi network), but my 5ghz was on 48, which looked to be unique. Channel 13 was already in use on another Wi-Fi network.
You can still find the older version of inSSIDer free. There is also a free version of Acrylic Wifi which does a similar job.
as far as I know this is still free
you can try downloading inssider3 (istumbler if MAC) and then run it. This will show the broadcasting networks round about you and their channels including your own. If you then enter your router and change your wireless channel to a free or less congested channel.
