Macbook - No IP address

Hi

For the last few months, my Macbook intermittently loses WiFi connection with the message "NO IP address". This issue is not affecting other devices in the house nor my Macbook's connection to other WiFi networks. 

Thus far I have tried:

  • Calling Apple - the advice was a reboot in safe mode plus renew DHCP lease but neither worked
  • Following steps in other Virgin Media community answers, but none of the following have resolved it:
    • Turn hub on/off
    • Reset hub to factory settings 
    • Log into Hub and turned off Smart Wifi (this seemed to stop the "No IP address flag" but made reliability even worse).

Re: Macbook - No IP address

Try this if you havent done the "separation" as well
________________

Log in to settings and go to Advanced>wireless>smart wifi - tick the disable “channel optimisation” box and save settings. 

Then, go to advanced>wireless>security, rename the 2.4 & 5 GHz network ssid's.  Just change 'em to whatever you like and something that will differentiate them (e.g - Alex_2 & Alex_5) -- 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 to connect to individually from the "available networks" list on each device. 
Note all your wifi devices will need re-connecting to the new SSID's and passwords.
5 GHz is always better/faster and subject to less interference (and is better for all iDevices ) than the 2.4 one - although the 2.4 one has the better "range" and some older/cheaper/dumber devices can only use this one. 
You should also use a wifi analyser App 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.
