Hello.
I having problems with the wlan connection. When doing normal surfing the connection doesn't break up, but if I ever start to transfer data more heavily the connection starts breaking up. Has anyone else suffering this? I use the 300MHz mode since one of my computers have buffalo 300 usb wlan stick. The router itself doesn't totally reset since I have started to use one of my machines trough wired connection and that machine keeps it's internet connection all the time. I have tested different security modes and different channels, but that doesn't seem to help.
The breaking seems to have become more frequent now, but it was there originally also. Also the router has crashed couple times so that it's red diagnose LED has lit and only taking of it's electricity has restored it.
I am starting to get feeling that maybe I have defective unit or something.
I've never had a problem doing transfers although I've only used G since I don't have an N adapter yet.
Firmware v1.60
I can confirm the WLAN Connection Break with FW 1.60.
But only WLAN->WAN AND if i use torrent with heavy Connections.
LAN->WAN does'nt suffer this Problem.
WLAN->LAN works flawlessly 6..7MB/s (Intel WLAN...).
Would be nice if this could be fixed in v1.6x!
Your symptoms seems very familiar. Except I haven't tested or noticed that during the break wlan -> lan connection is still working. But good to know it's not just me then. Time to switch routers again. Ass offtopic ranting: This buffalo is my seventh router in price class between $40-$200. When I will came across router that workd flawlessly.
Same here. Wireless breaks time to time. Even with normal web browsing... :(
Had the problem with 1.60 and still have it with 1.64
Check the log data ('Diagnostics'...'Log'), just after you get a break in connection - you will probably find a wpa rekey event. I had this, with a break lasting between 20 -30 seconds - you can change the rekey interval from once every hour (default) to half a day (1440 minutes) but I had also upgraded to 1.64, which is very unstable.
I have since replaced my WHR-G300N with a router from another manufacturer, rekeys do not cause dropouts anymore. I'm holding on to my WHR hoping Buffalo will get this sorted out soon.
for me, when i transfer a large file (> 200mb), it can break at any time and i'm hard wired to ethernet port 1. forget about going to dd-wrt firmware, it won't fix it. my linksys wrt160n is the primary router now.
I'm experiencing these symptoms. WHR-G300N Ver.1.64 (R1.05/B1.09). Wireless breaks for a few seconds in the middle of large transfers, like an itunes podcast download (so wan-wireless), moving directories between machines (wireless-> wireless), backups (wireless->wired NAS). Auto channel selection is off, which should be the default I think - it was the cause of a slew of other problems.
Breakage happened reliably when I started itunes on my XP wireless laptop. I have my music library on a (Buffalo) NAS, wired to the WHR. The Itunes downloads directory is also on the NAS, and itunes was configured to start downloads on startup. With *no other* network traffic on my LAN, and monitoring RTTs with ping from laptop to NAS, I would see a spike in RTT and then timeouts, lasting a few seconds, enough for windows to take the NAS filesystem offline. If I happened to be playing music at the time, itunes would mark the song as missing (really annoying).
Ping RTTs from the (wired) NAS to the WHR never change. So my symptoms are isolated to wireless. However, this is definitely *not* a channel problem. I've tried all channels and the RTT spikes manifest only and always on sustained read/writes to the NAS (which is really my only way to generate sustained network traffice easilty), or on sustained writes between wireless devices. The spikes don't always necessarily result in timeouts (at least according to ping), but they are always there with sustained network traffic. Seems to happen more often on writes, but not enough evidence of that to be sure.
Nothing in the WHR logs for the times of outage. Simultaneous pings to the WHR from laptop also showed timeouts, so it seems the device itself is dropping packets. I haven't hacked IP in 20 years but it sounds like a queue/buffer size problem to me.
A workaround for the itunes problem was to make the download folder "available offline". This didn't stop the network outage but would allow me to start itunes without losing the folder. My music directory is entirely too large to make available offline, so I currently cannot listen to music while there are downloads.
This is extremely frustrating. Willing to work with it a few days but very close to exchanging for another brand. A wireless router that loses wireless when it gets traffic is worse than useless.

This is unacceptable.... I can't believe they are not addressing this with a firmware update. We need that update really fast.
My computers are disconnecting all the time. Sometimes, I have to turn off the wireless cards... other times I have to reboot the router...
Please FIX IT !!
Christo do you see any wpa-psk rekey events in the log when the connection break occurs?
Joe,
I'm running open (no security, no authentication - my house is in the middle of nowhere), so I don't get rekey events anyway, but the logs show nothing at these times. Is there a way to increase the logging verbosity?

I have same problem.
Model - WZR-HP-G300NH Ver.1.65 (R1.66/B1.03)
Mode Switch Status - Router Mode ON
No BitTorrent active, Lacie USB HD linked.
Cable modem Cisco EPC3000. Home network of 1 Linux laptop and 2 Linux based Satellite RX'x - all connected by cable. 2 computers using WLAN - mostly only 1 is online. Connection lost/frozen quite many times per day when I had external HD connected. Now I dropped it out so lets see if it helps.
But if reason is NAT table filling so quickly - aren't there any other solutions than restarting? How about built in "cronjob" like in Linux clearing tables automatically say every 4 hours etc. As you see - I have new software but problem still exists.
What makes you think the problem is related to NAT? For me the symptoms are associated with sustained traffic between two machines, this shouldn't impact NAT.
Is there another thread you are watching in which this was discussed?

This thread have same kind of problems - http://forums.buffalotech.com/t5/Wireless/What-s-going-on-my-WZR-HP-G300NH/td-p/12932;jsessionid=178880964CE3C01460EA1FC8CA9BE8A6
I'm pretty certain this problem is not related to NAT.
Problems still occurring....very frustrating.....a couple more days of patience and then back it goes...

I was having serious connectivity problems with my G300N (1.64 firmware) and a Nokia N900. Large file transfers would almost always freeze at some point. This problem disappeared when I turned 40Mhz mode off.
But now I have another problem: if the connection is idle for a while (~5min), the router drops the connection. I get the following message in the router log:
ra0: had been aged-out and disassociated : ec:9b:5b:xx:yy:zz
(ec:9b:5b:xx:yy:zz being my device MAC address)
For me, it is not a NAT problem, as I'm using the the router in bridge mode.
As a temporary resolution, I've shortened the DHCP lease time in my LAN so that the N900 has to renew it's IP lease every 4 minutes. That seems to work so far.
This problem happens at 20 or 40 Mhz and on any manually selected channel.
Basically this product doesn't work. The problem is not spurious. It happens every time there is sustained wireless traffic: downloads, backups, media streaming. Can't believe a company can sell a wireless router that stops wireless routing when it actually gets used.
I posted my first problem 3 weeks ago. No help. Ordering a linksys now, will return the buffalo to amazon and post my product review there. I gave it a fair shot, I think.

So, what's the verdict? Any chance of a fix? I'm having the same problems since day 1!
And to be honest i am getting a little tired of it!
Tell us if its a hardware problem, so we dont wait for a fix ... or tell us SOMETHING, atleast make it official!
I was thinking its the firmware, but it seems its a harware problem .... so, any fresh comments will be nice, thank you
Please... at least someone from Buffalo could confirm the problem and state if it is a hardware or software problem? Is there any new firmware on the way? Or I should simple consider to buy a new router from linksys or dlink?
juise, I got exactly the same problem.
And plus, the wifi module of this router freezes when downloading bittorrent.
I am now regretful to have bought buffalo router.
