The 7940 and 7941 are the same phone just the 7941 has more lines. Changing the firmware is required for both the 7940 and the 7941. They use the same files and the same process. The files you need can be found here on the site. http://broadband-hamnet.org/download/7940/NG5V-Cisco-11-12-2014.zip 

Hope this helps.

My apologies I was confusing the 7941 and 7960. The 7940 and 7960 are the same with the 7960 having more lines. The files you need ARE different. The 7941 and the 7961 use the same files. This site has some good instructions on changing the phone and getting the right files.

Easiest way to power through the Ethernet cable. I used blue and blue/white as positive. Brown and brown/white as negative. Cut at both ends of the cable so no power running back into my computer. Twisted the the blue two together, and the brown two together. Soldered the power supply at one end and the plug on the other.

Thanx for your quick reply HP2AT. I tried it without the extra switch. I used a lot of timings, but no luck so far. I quess the switch is needed to overcome the time Windows need to restore the ethernet cable connection. I give it an other try tomorrow. See if I can pick up an ethernet switch somewhere that isn't answering to 192.168.1.1.

My LinkSys MESH nodes are running 1.1.2 firmware.  I see that 3.1.0 is available.  Two questions:

Am I correct in guessing that 3.1.0 is not backwards compatible?

As my MESH seems to be running OK, what improvements would I see with 3.1.0?

Sorry if this question was asked before. I am quit a Noob regaring firmware flashing so all the stuff on this forum is a bit hard to follow..

I once flashed a few Linksys WRT54GL V 1.1 modems to use them as a Mesh node. Unfortunately the 2.4 GHz network is so occupied that it wasn't possible to make the disired connections. The project moved to the dark attic.

Now I like to restore the old firmware of the routers and afther that I would like to flash a version of DD-WRT into it. I want to use them as an repeater during some camping time.

This is what I have now.

A Linksys modem type WRT54GL version 1.1 responding to  HTTP://localnode:8080/ and comming up with the login and mesh node screen.

I can select the admin part and then let the modem look voor the BIN file. This he doesn't read.

It's the last updated firmware file version 6.0  downloaded from the Linksys site.

Is it possible to flash the Original firmware back in? and how is it done?

hopefully somone can help me out.

Yes the node is still online

I sent an email to Microtik a short while ago and they seemed very interested in the project and in helping in anyway they can. Hopefully someone will pick this up.

Hi, I need a little help and guidance with a voip install. I am using a raspberry pi 2 model and  linksys gl broadband ham node v 3.1. I followed Jim Kinter's video tutorial and all proceeds smoothly until I check mesh status. My pbx is listed but "asterisk" is not listed under services. I checked the ip and subnet mask and they line up with the pi. What am I missing? Is it the gl model?
