I am looking to buy two routers and bridge (I'll post a seperate topic on this?) them together. From what I can tell, the G and GS are on to v5 now which don't allow for 3rd party firmwares. I have been looking at the WRT54GL. I have a few questions I was hoping to get some help with. 1. Is a WRT54GL essentially a G v4? 2. Will a WRT54GL allow for 3rd party firmwares? 3. Other than going to local stores and and searching for serial numbers to match a G/GS v4, is there any other way to find a G/GS v4? Thanks in advance.
