Wireless router behind another router

Specs: Windows XP
I am trying to put a wireless router behind another router. I have DHCP on the wireless router disabled and connected wireless router LAN port to wired router LAN port. The wired ports on the wireless router work fine. The wireless signal strength is good and shows a good connection. But wireless connectivity to the internet is poor. Ping to the main router shows most packets are lost. I have assigned the wireless router an address outside the DHCP range but in the same group. Main router is 192.168.15.1, wireless is 192.168.15.2, DHCP range is 192.168.15.100 to 192.168.15.130. I though the router might be bad as it is an older one so I got a new one - same issue.

Update - found the problem. The wireless on the old router was still connected and running. Had some trouble getting wireless turned off for it. First speedtest.net run on new wireless showed low download speed (0.35 Mbps) but later showed same as wired (1.3Mbps). Not sure why the first test was so low as I have tested several times and now get the higher number.

The old router (DI-524) even seems to display its web interface slowly although the wired ports still seem to work ok at least LAN to LAN. Any suggestions on this? Is it just failing?

From the looks of it, you've got everything configured correctly so I can't think of what may be causing your issue...........especially since you've replaced the router with a newer one.

But wireless connectivity to the internet is poor.

You do understand that wireless is inherently subject to lag and latency issues which could easily cuase poor connectivity? This may be nothing more than a simple case of wireless being wireless.

Ping to the main router shows most packets are lost.

I'm guessing you're pinging from a wireless client. If so, try the same from a wired client. Do both at the same time (if possible) and use the /t switch with your ping (it makes the ping continuous) and let it run for a minute or two and then stop it (using Ctrl-C) and check the stats on 'packets sent' versus 'packets lost' on both and report back.

If you only lose packets on the wireless client, it's the client, the client's NIC, or just the normal wireless issues.

Remember, wireless is never as fast, or as reliable as a wired connection. And, it never will be.

It matters not how straight the gate,
How charged with punishments the scroll,
I am the master of my fate;
I am the captain of my soul.

Thanks for the response. I now get about 18 ms time for www.google.com on wired and 20 mS for wireless. I am happy with that and understand wireless will be a bit slower but my DSL is not nearly as fast as the wireless so I didn't expect major differences (which is what I had before).
