The other day I bought an Linksys WRT54G vr4 from Ebay. The router works great and I would like to update. I have now an D-Link 624 and I updated that router too. The old one is running two VOIP adapters the computer direct and one wireless. The router is hook up to cable Internet. The speed is average 6 Mbs so I am happy with that. What should I use to update I heard that DD-WRT is good but it has the option of VOIP. What should I use to update? Need help.
