so i recently purchased a new router, a dlink 686L. for the most part it has been fantastic although i really want dd-wrt and its not yet available. right now my big issue is that i have two computers on the second floor of the house and both are having issues with connection quality. the indicator in windows tells us full signal however pingtest will randomly have abnormally high ping and jitter and rarely even a bit of packet loss but the connection quality never drops. from pinging the router i have determined that the issue is occurring from the wireless connection as the wired system in the house has been fine. any ideas what may be wrong?
