Networking issues Hi, I have an extended star network, with ISDN links connecting all spokes to the central hub. On the central hub i am hosting an application. At each of the spokes i am running a wireless network. I have over 400 spokes, in which the wireless network runs fine. One spoke intermittentally gets a DHCP leased IP address and DNS doesn't work at all. The application is IP based and hence fails, intermittently. When i try to assign a static IP to the wireless device it can not get on the network, unless i assign an IP outside of the DHCP scope but inside the LAN's subnet. I have replaced the router and the switch with new ones that have been tested and worked. I have disconnected the wireless network from the LAN of the problematic spoke and validated it works by taking it to another site and running it successfully. I have also replaced the wireless devices on numerous occasions. I get 4000+ms pings from the wireless device to the application host and sometimes i cannot even ping the DHCP server. What else can i do to get my application working?
