Hello ... I have run this by the Soekris list, but didn't get any responses. An update to this may indicate that 2 radios WITHOUT Captive Portal turned on, appears to reboot when at least one PC in the office attempts to connect and browse through the unit, or attempts to manage Monowall. I have seen some discussion on the list about power saving modes on some PC clients possibly causing reboots, but these settings aren't 'on' on the computer. Granted, in the test bench environment, I only have 2 'rubber duckie' antennas mounted to the back of the Soekris .. One for each radio. In a working environment, these would be separated, usually directional antennas. Possibly receiver overload on the radio side, and not a Monowall issue at all?? Original post: I have a few issues regarding the 4521, Monowall, and Captive Portal I suspect this is a Monowall issue, but thought I would run it by this group, to see if anyone else has had the issue. System: 4521, 1.26a BIOS (originally had 1.23a, upgraded, and have the same issues) 2 PCMCIA NL-2511CD Plus ext2 radios Empty Mini PCI slot Empty PCI slot Sandisk 64Meg Compact Flash Monowall 1.1 2 radios without Captive Portal turned on, seem to work fine .. answering DHCP requests, and routing out through the WAN. 1 radio WITH Captive Portal turned on, RADIUS authentication, works fine.... including when the 2nd radio is physically mounted in the unit, but not enabled via BIOS. With the 2nd radio activated in BIOS, and Captive Portal turned on on Radio1, the router reboots when a radio client attempts to authenticate. Sometimes the reboot is before the Radius authentication, sometimes after. A related issue for Monowall 1.1, is it appears to only allow Captive portal on one interface at a time. .. I've not seen where it can be implemented on 2 radios simultaneously. When Captive Portal is implemented on the 2nd radio .... it blocks outside access, but doesn't bring up the Radius screen .. only get a ' Page not found' screen. Any ideas? Thanks for your time.
