Bluesound Node Issues After the Firmware Upgrade

"I have a node 1 that froze up a couple of weeks ago..."

rocray, if by "freezing up" you mean its stuck in a red LED mode, try reading through the link below, particularly the last few posts and see if that helps. It helped me with my Node N100.
Good luck.

kalali, thanks for the link. I did try a reset last night,it did start blinking for 20-30 seconds,and then went back to solid red. I will try the reset again ,but this time I’ll connect it via Ethernet cable. The funny thing is my Node froze and I ordered a 2i before this potential fix. Isn’t that the way life goes sometimes? 

I have both a Powernode 2 and the original Powernode N150.  The 2 handles updates just fine, but the N150 will go into a solid red light.  Sometimes connecting by wire will finish the update, but I had to do the last 2 updates via USB stick.  The instructions are on their web page.  Try the USB route before you do a reset.

One little trick for the rest to work is you have to hold your finger on the button before you plug it in the outlet, and keep holding it until it starts flashing red. It should then turn blue if connected to ethernet or turn solid green if on the WiFi. Then just follow the set up process for WiFi...
 

I really love my Vault 2i but the past few upgrades I had issues.   Works fine now but after the last update I had to reboot the unit , it would not communicate with my tablet.
