Supports Y/L WF40 Wi-Fi USB Dongle and IP Phones T27G,T29G,T46G,T48G,T46S,T48S,T52S,T54S,

Worked well, plugged them in, the phone found them right away. Went to menu, network, wifi and scanned. Found our network, programmed in the password and poof, connected. Thank you

Does what it needs to.But It does cut in and out at random during call making it hard to hear what others are saying. Comes off unprofessional. Could be my internet. Gets the job done for the most part. Would recommend.

These items are plug and play in Yealink 27G OOMA phones. We've had two instances when "network upgrade" has caused failed wifi connections in all phones, so keep a cheat sheet nearby for reconnecting to wifi (password not lost).

I received my order and promptly used one of the two WiFi units on my Yealing phone. Within 5 minutes the unit failed. Switched it out for the second one and so far it is working fine. Please replace the defective unit.

Seems kinda buggy so far. Network disconnects and reconnnects occasionally. I need to do a few more tests, but it seems okay. Both Bluetooth and USB adapters can be used simultaneously via USB hub, but the hub may be the problem.

These wireless usb devices worked perfectly on the Yealink T46s phones. No problems with picking up with wireless networks and setting them up. Tested outbound calls and they worked perfectly. No loss of voice quality.

Used some of them to connect a voip phone to my wifi and one to add wifi to an older desktop. Both cases it worked just fine and setup was a breeze - plug n play

Bought for my Polycom VVX411 phones and they aren't compatible according to my IP Phone vendor. So I now have these that I don't need. Check your phone's compatibility first.
