Hi,

My set up is a zoom cable modem/router 5352 as the AP. I have three Cisco routers running wireless as repeater bridges. I configured these following religiously the dd-wrt wiki. They are a couple of WRT54G and a WRT54G2, all of them running with build 25697 mini except the last one running micro, all of them connected to the zoom router with virtual interface (different SSIDs from each other and from the AP).

The problem that is driving me crazy is that all of them will work fine for a few seconds, freeze for another few and so on. The Status/Wireless show different number of transmit errors for each device and no Receive errors. I collected advice from older postings and these are the things I tried:

1. Keep the transmit power at or below 84mW,
2. Clone the MAC addresses,
3. Make the sensitivity range (ACK Timing) equal to zero,
4. Change the security settings (now running WPA2/AES),
5. Change the channel number & bandwidth in the main router,
6. Tried different builds.

None of these worked for me. Any ideas?

Thanks

Try following all advice in the peacock announcement, including build advice for those older router. You might find that those routers lack the power to do what you need them to do.

I read the posting and followed the recommendation on the builds. So I installed 14929 and so far it seems to be running OK. The transmit errors are very few and I haven't seen any intermittance to now.

Thank you very much for your help.

Unfortunately, the intermittance is still there. One more piece of information: if I ping from any of the wireless connected machines (that are wired-connected to the repeater bridges) to the AP main router, I don't miss any packet. On the other hand if I ping from the same machine to an external site, e.g. google.com then I miss lots of packets. Does this mean anything?

I made some progress. As I said in a previous posting, I had three repeater bridges all connected wirelessly to the main AP router. I noticed that one of them was "freezing" more often than the others. This one had three machines connected with ethernet wires to the LAN ports. So I thought that perhaps is not that the wireless link was freezing but that the router/switch could not handle these three machines, being one of them a lightly loaded mail server (SMTP port 25). I unplugged this and another machine and ping'ed back to google.com with the only one connected. Voila! This time it was zero packet loss. So the issue seems to be how the router operates regarding the switching. I wonder if there would be a way to make it "smoother" rather than completely stopping one or more of the ports.

By using the program "nethog" I could see that the actual internet traffic was minimal, so why is that accessing the internet is so choppy? Is there any thing inherent to dd-wrt or the wrt54g that makes this problem to arise?

[danielsender]

As I wrote in my previous posting, I thought that perhaps the WRT54G was not capable of handling three machines hooked up to the ethernet ports (albeit very light traffic) I replaced the WRT54G with the RT-AC66U that is considered one of the fastest routers today. I successfully installed build 25974 (26081 has wireless issues) and set it up as repeater bridge. But when I tried pinging google.com the problem is still there, about 20% of packets lost. As I said before, there are no packets lost when pinging to the main router that seems to indicate that the wireless connection is fine, so can some expert suggest what could be the problem?

anybody?

In case somebody can figure this out, I'm attaching the /var/log/messages of the router:
