Dlink multiple Routers DHCP Stops Responding?

Dlink wasn't sure why I was having this problem and I am looking for
advice.

We have a 20,000 sq ft. facilty we are trying to make a free wireless
hotspot.

Using a Dlink DI-614+ (rev. B) acting as a central router gateway with
DHCP enabled.

We have three 514 wireless routers that are hard wired back to the
614. the 514's have DHCP disabled.

All routers are spaced through out the building using the same SSID
with different channel numbers. 6,1,11,1 all spread out so the two
using channel 1 do not over lap.

The problem we are expierecing is the 614 will stop reponding and will
need to be powered down. Once the power is cycled it will function
fine for a time and then again become unresponsive.

There seems to be no pattern to the time it stops responding. Some
time it will stop when it is in use (3 or 4 users) and other times
when no one is on.

We are using DNS redirector running on an XP Pro machine to offer the
welcome page. This is hard wired to one of the ports on the 614.

Any thoughts why this would happen or a way of correcting it?

 

I accidentally sent this to Dan. Sorry about that, it's meant for the NG.

I had the same problem, if I read you correctly. Wireless routers were set
up as an access points on a wired router. Things would work for a few
hours, then we would lose access to the internet. The laptops would still
show the same IP, but an ipconfig /release . . . /renew would not work. I
replaced the routers-as-access points with real access points, and the
problem is solved.

I haven't been able to trace the actual problem. It seems to occur for me
on Win2K laptops (several brands) with several different wireless PCCards.
My laptop with XP did not exhibit this behavior. I didn't want to demand
that anyone wanting to use this wlan has to run XP, so I changed the
hardware.

I'd be curious if anyone has seen this, and perhaps traced it through.

Thanks Barry,

Sounds like I need to replace the routers with access points.

Can anyone tell me the difference between a wireless router and
wireless access point?

I am looking at replacing tht 514's with 3 DWL-700AP's.

Here is my set up:

DI-614 acting as the central wireless router with DHCP enabled.

To that the 3 700AP's will be hard wired back. They use the same SSID
and different channels.

Thanks, Dan

 

Looks like a real straight forward approach to me. You can probably sell
the routers on eBay. That's pretty straight forward too!

 

A wired router in the SOHO category (sometimes called a Residential Gateway)
is really two devices in one: a router with two interfaces (WAN and LAN)
and an Ethernet switch. If you see 4 LAN jacks, then it really has a 5 port
Ethernet switch with one of the port connected internally to the router LAN
interface (which is not exposed externally).

A wireless router has all of the above plus a wireless Access Point. An AP
is basically a radio transmitter and receiver connected internally to an
Ethernet jack. In the wireless router, another port on the Ethernet switch
is internally connected to the Ethernet port on the AP.
