I have a Qnap NAs with squeezebox server on it. In the living room I have a Joggler connected to stereos. I control Squeezeplayer on Joggler by 770 in the kitchen; web radios, spotify, personal music archive. I'm using 770 wifi with g-connection. 770 does not connect to my airport express but is working at the same time with a g-router as I use n with airport for android tablet/Huawei and macbook (not frequently used)

kernel speed patch.
I had he2008, he2007 and 2006 on my 770. I had not used 770 for a long time and found out that I could not connect to wifi. I reflashed and got wifi back. Then I applied kernel speed patch and lost wifi again. So the first reflashing had not been necessary if I had realized the speed patch was the reason for not connecting to wlan. Hope that is of help to other 770 users.
