Unifi not using 802.11n on 2.4Ghz??

[themightymrp]

We have just switched our WiFi over to pure Unifi and have encryption set to WPA2.

 

All of our laptops support 802.11n (some only 2.4Ghz and some support 5Ghz). However, everything seems to be connecting using 802.11g and not taking advantage of the higher speeds.

 

Any ideas why? Even on 2.4Ghz everything should surely connect using N ? We are running Unifi software version 3.2.1

What encryption method are you using? TKIP or AES?

[themightymrp]

TKIP but I think we've also tried on AES. Would that make a difference?

[WifiWizard]

AES is always the recommended encryption method with WPA2 as it is stronger. I have also come across issues where TKIP can limit devices to 802.11g speeds. Let me know if changing this resolves your issues?

Also, it will rollback standards if the signal quality won't uphold the higher standard. have you tried standing under the point and seeing if you get N and then walking away?

OK, the answer was to switch to AES!! That seems to have sorted it so thanks for that.

 

Wish I'd known beforehand that TKIP would bring it down to G speeds but there you go.

AES has stronger encryption than TKIP and it's fair to say that slowly it's being dropped.

 

As far as I know you can't use TKIP with wireless AC for example - not that you'd want to, but again you'd be reduced to G speeds.

Just found the proof for this, TKIP cannot be used for high speed connections i.e. 802.11n or 802.11ac
