Hello,
I also have connection issues and have tried 2 different Ethernet cables without luck. I have use the wp4.sh to connect and can reach the web interface intermittently e.g. 1 in 30 attempts works.
My WPS light stays flashing blue for a very long time, then stops for less than a minute and goes back to flashing blue again.
I have also tried the reset button but it never seems to reboot.
I cannot ssh in as the pineapple wlan0 does not stay up long enough, it only comes up every few minutes for a few seconds.
When I first got the pineapple it seemed to work fine, I did a firmware upgrade and it never came out of the waiting loop. After 45mins I rebooted the pineapple and it worked fine and I used it successfully or an hour. However, after trying to use it again some days later I now have this LAN connection issue. Since I can get to the web interface intermittently, I am unsure what is wrong.
Any ideas?
