Hi, we have a problem with zyair G-4100 which is very hard to debugg. Zyair G-4100 is hooked to hughes satellite modem with a satellite service of 1.5mbs down and 450kbs up. We have managed to limit the per-user bandwidth to 128kbps down / 64kbps up, because prior to that, a single user was usually slowing everyone else down. Since then, and especially after upgrading to the latest firmware, things are better. However, every now and then, especially when the session list grows to be 30 or over sessions from one user, the router web administration page is slow to respond or nearly non responsive. We also tried limmiting the number of sessions per user to 30 but end up with not that much better behavior. In all the instances DHCP functions pretty good as I am always able to get an IP. However the login page which, every new user should see when trying to access the web, is not comming up. Refreshing it random number of times would end up bringing the page up, and sometomes not. Restarting the router doesn't always help. Seems that things get better and worse at random but problems always start when one user opens up a large number of sessions (tcp or udp connections).
