I lost wifi on hub 3.0

OK so my broadband went off for a while, it came back about 30 minutes later and my wired connection to my computer seemed to work fine (although it did appear to be a bit "snaggy" at times as can happen after the broadband first come back.


However I found none of my wireless devices (amazon fire tablets and android phone) worked.

It was clear my usual virgin media connection point ie VM023938 (or whatever) was no longer there.

I tried power cycling the router a couple of times but it was still the same, working but no wifi.


I am wondering if some of the default setting are wrong?

(under advanced - security)

Of interest are."WiFi Network Name (SSID) broadcast  Yes/No"

This is set to NO for both 2.5 and 5.0 Ghz


And also on  - advance - wireless signal

Smart WiFi

 Enable Channel Optimization  Was on, meaning a lot of the boxed were greyed out
Anyhow it now worked, I made some changes, I set broadcast signal to yes in security
I also changed some values in wireless settings.
In smart wifi
Smart WiFi
 Enable Channel Optimization  -------------I changed to untiicked
 Disable Channel Optimization  ----------------- I changed to ticked
I also have both channels set to manual.
I may be able to set these back to auto and an enable smart wifi again, but
if it aint broke don'e fix it.
I will see how it goes.
Here is record of my setting I changed.

Re: I lost wifi on hub 3.0

Now I think it was just broadcasting the SID that fixed it.

But I though I tried that last night with not success!!

so pleased to have fixed this

Hope this help others with the same issue.

I maybe be able to change some setting back ie the optimisation stuff I set to manual, I think it was
probably broadcasting the SID that did it, but I can play around at my leisure now that I am more confident in what I am doing!
