Hello, to avoid creating one more thread i've decided to post in this one.
Like OP, i'm also having packet loss problem with WHR-HP-G300N i've purchased two months or so ago.
It came preloaded with svn revision-14512 DD-WRT software. After being left to run for a day or so, it started to make a noticeable packet loss. I tried to do some research on the intertubes and found out that upgrading to the latest (14998) solved this problem in many cases. It did help, but it did not solve the problem completely. Now the packet loss problem occurs, but at noticeably longer intervals, it had worked for me for 8 days without any problem, and it has als occured on the second day. So far i haven't noticed any correlation between packet loss issue (it always starts suddenly and noticeably) and my network usage, although higher network usage usually causes the problem to occur faster. I will try to switch to user-friendly firmware, but the main reason why i bought this one particular router was because of the DD-WRT software and it's abilities.
The packet loss occurs on all outside traffic, irrelevantly of the site i'm pinging, and it occurs directly after the router and ceases immediately after i reboot it (either by plugging it off and on by pulling the power plug or via web-interface "reboot" button) and usually is at 25-35% all across the path in traceroute diagram (using PingPlotter free version). Also replacing with my old router (which has its own problems, but packet loss isn't one of them) immediately solves the problem too.
I'd like to know, whether buffalo's (and/or DD-WRT's) developers are aware of this problem and whether they are doing something to fix this issue?
Thank you in advance.
