Wifi not working

[Campb11]

We were using the Internet without WiFi (Ethenet cable works well)without problem

I need to use WiFi to set up the new printer but cannot connect to the wifi.

Please help

What Hub model do you have? What printer model is it and is it capable of connecting on both 2.4 and 5 GHz - or just 2.4?

If its a Hub3/4 try this...

If you haven't done this already - try it first - it helps sort some Hub3/4/5 wifi issues for some devices.

Go into the Hub’s settings. Type in  http://192.168.0.1  into your web browser’s url box and login with settings password on the Hub's base sticker (or your own if you changed it). Then in Advanced>wireless signal >smart wifi - tick the disable “channel optimisation” box or “Smart Wifi” box and save settings.  May be different pathways and wording on the 3 Hub types
Then, go to advanced>wireless signal>security, rename the 2.4 & 5 GHz network ssid's.  Just type over to change 'em to whatever you like and something that will differentiate them (e.g - Campb_2 & Campb_5) Try to avoid spaces and periods in the SSID names as they can cause issues with certain devices. Use the same password for simplicity, 

Then, apply settings and restart the Hub.  Your 2 wifi networks will now be clearly separated - and you can then select the network you want each device to connect to… individually from the "available networks" list on each of your devices. 

Note all your wifi devices will need re-connecting to the new SSID's and passwords.
All things being equal, 5 GHz is always better/faster and subject to less congestion/interference (and is better for iDevice speeds than the 2.4 one - although the 2.4 one has the better "range" and will be needed when the 5 GHz drops out of range and some older/cheaper/dumber devices can only use this one. 

You should also use a wifi analyser App (or Airport Utility on iOS) to check which 2.4 channels are being heavily used around you and move yours to one of numbers 1,6,11 that is least so, but it wont help if there is other interference.

See if these changes help - you will lose any “seamless roaming” benefits but it may not matter and you can always change the settings back by doing a " pinhole factory reset " if you prefer the way it was - or it doesn’t help.

Hi Campb11, thank you for posting to raise this to us!

Sorry to hear you are having issues with your Wifi! Have you ever had working wifi? If so, when did it stop working?

Thank you to jbrennard for their advice and support - I would also recommend trying a pinhole reset to return the hub to its factory settings and refresh all connections. Do be aware it will change any personalised settings on the network (Eg network name if you have changed this) which will then be set up again later. 

If you can please try the pinhole reset and let us know how you get on. 

All the best!
