The kids were delighted that I bought something with “pointed ears” (I couldn’t explain the real purpose of those antennas to them…)
I finally got hold of my Linksys WRT54GL today. I connected it, did some preliminary tests with the Linksys firmware, confirmed that it did not work as a Wifi-Ethernet bridge out of the box, took a deep breath and started the flashing process with a new firmware developed by Thibor.
And it worked!
I promptly followed this to transform my WRT54GL into a brand new Wifi-Ethernet transparent bridge featuring a 4-port Ethernet switch!
The only thing that does not work is DHCP relaying. I had to assign static IPs to my PCs but this is a very very minor issue. Apart from that, the Linksys rocks and now I can browse the web from three different computers.
Life is cool :-)
