Everything was fine for 2 weeks, and then one fine day, the router just stopped working. Cisco being all rich and mighty, just decided to replace my router. Yay, good for me. One more week later, the second new one was gone. Dead in the middle of the night when there were no power fluctuations or anything. I was quite pissed off and wanted a different brand. In the meanwhile, I got the power adapter checked and found out the adapter was blown. Ah, so that was the culprit. Got a new adapter and the router worked fine with that. Turns out that Cisco or their support personnel don't care to even check if the router is bad or the adapter is bad...you're just given a new piece. Oh and I already know of 4 other people who had similar issues with the v5's power adapter.
Right, having ranted about that above, Versions of the WRT54G until v5, were all running Linux on them. This meant that you could flash the router and install better software on it like OpenWRT or DD-WRT. When Cisco bought out Linksys, they also ensured that there was only one opensource model, the WRT54GL and that too only available in the US (off the website(s)). The rest of their lineup would run VxWorks, which is what my v5 came with.
A while back zoneee pointed me to the Vxworkskiller link on DD-WRT and then proceeded to successfully flash the only v5 we have at work...and was needling me to give it a shot...so yeah, my v5 has now been running DD-WRT v23-micro for the last 13 hours or so without any issues. Yay.
