So much better than original FW
I only 'discovered' OpenWRT a couple of days ago and quickly dis-proved two beliefs I had about the software, I thought it was only useful if you need extra features not included in the manufacturer's firmware and that it was only for Linksys routers. how wrong I was.
I have a new TP-Link wireless AP. This thing had a weak signal that keeps dropping out and needing a reboot. I had tried everything to make it work reliably and was on the verge of chucking it out until I noticed that OpenWRT would run on it. The difference was noticable straight away, I have a much more stable network and can now even access it from further afield than before. I honestly don't know why TP-Link bothered trying to write their own FW, just ship the thing with OpenWRT, or have the installation instrictions as the first step in the manual ;)
