This problem seems similar to the issue we had recently. We originally had all of our (bridged) radios on a 10.0.x.x network with a Class B Subnet (255.255.0.0) - Started seeing real weird issues with the new gear we were deploying - Tranzeo / UBNT had same problems. Clients would just drop off

Re: [WISPA] no net but ping works

My point being with ARP you can't ping. Regardless if the ARP happens right after you issue the ping command or it learned the MAC from ARP hours ago, you still need ARP to do ping. Josh Luthman Office: 937-552-2340 Direct: 937-552-2343 1100 Wayne St Suite 1337 Troy, OH 45373 On Thu, Aug 26, 2

Re: [WISPA] no net but ping works

Every time an IP packet is sent over an ethernet interface, the destination MAC address needs to be resolved to either the MAC address of the gateway or the destination IP on the same subnet. If an existing (non-stale) ARP entry is in the ARP table, it will use the MAC address from the cache. Oth

You have to set it to >512 for DNS. Remember that DNS is UDP so if the packets go away because the wireless medium you are using is lossy then there are no more re-transmits. Setting the RTS/CTS to just at the size of a UDP DNS packet creates a virtual TCP-like network for those sized packets. ry

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.
