Wireless adapter no longer detected?

[agtr]

hi
I would advice 4 things
-first, check that the network setting in menu is WIRELESS, not wired, because it sometimes turns to wired after upgrade and downgrade
-second, try resetting the tv by pressing the exit button for 10-15 seconds. while doing this, make sure that the wireless dongle is not plugged to the tv
-third, discoonect the tv from main electrical plug for 10 minutes, sometimes this corrects minor issues
-fourth, use a lan cable to connect to internet, later try to swicth to wireless mode
regards

I had a similar problem in the past. if I remember correctly, I removed the dongle from tv, since it did not work. a few days later, when I plugged it again, tv prompted that it found a dongle and asked if I wanted to switch to wireless instead of wired.
have you tried removing it and reinstalling it while tv is on?
by the way, I was using the 3010.1 firmware a while ago. After I downgraded to 2004, I had problems with CI module (tv did not detect it). After resetting the tv by pressing the exit button for 15 seconds, TV started detecting it again. you can try that option too, if you want
