I doubt it's DNS but you can test that. When they cannot connect via URL have them try to access the site via IP. If they can access it it's DNS, if they can't it's ARP.
If it's not DNS, the next step is to log into your router when the customer cannot connect and see if there is an ARP entry. I'm betting it's timing out out an not refreshing until you ping the gateway from the CPE (Ping is ARPless). Finding where/why the ARP request is dying is the tryicky part. With the customer still unable to connect, log into the AP and ping the CPE and then have the customer try to load the page. If that works the issue is probably between the AP and CPE. If not, move to the next device up the chain each time pinging the CPE until the customer can connect. As a temporary measure you could add a static ARP entry in the router but that's a bandaid and may mask a more serious problem. - Jerry -----Original Message----- From: [email protected] [mailto:[email protected]] On Behalf Of Mark Dueck Sent: Thursday, August 26, 2010 8:15 AM To: [email protected] Subject: Re: [WISPA] no net but ping works I have about 25 clients on this AP. I think only 2 of them are NS2's, the rest are SL2's and they are all updated to 5.0.4 firmware, which has the fix for the limited connections that the 4.x firmware had. All the Tranzeo's have their RTS at 3000, their default. I checked the NS2's, but I can't find that setting in the webGUI. How do I check/change that?
