Maybe some of _their_ equipment (the modem's counterpart) is broken? > The only problem is > that my laptop can't make a connection while my older iMac can. The Internet connection itself is a matter of the modem/router, while access to the router a LAN thing. You could try to check (or exchange) the cables connecting the devices to the modem/router. > I've run bsdconfig each time and it appears that the network interface > is enabled, but that doesn't help with the laptop. That is not needed. I assume your endpoints are obtaining their network configuration via DHCP from the modem/router (which is common today). If this information changes due to rebooting the modem/router, you just have to re-initialize your network interface: # service netif restart This should get new DHCP information and configure everything else as needed. > It seems that the > only way I can restore access is to reboot the machine and that is > rather a nuisance.

With a separate modem, you typically have better control of what happens (or at least you can examine what's now "hidden" inside the modem/router), for example PPPoE connection creation or the general packet flow. Basic tools like ping, netstat, and tcpdump can help diagnosing the actual problem. But sometimes, it's simply just a bad cable... > Does anyone have any suggestions to resolve this? Thank you. Check cabling and modem/router, replace and re-check. In worst case, inform the ISP so they can check from their side (if you have verified that on _your_ side everything is fine). What you experience with Firefox might just be a follow-up problem originating from a flaky internet connection - you never know how "modern software" like Firefox will react when something is not 100 percent working. :-) -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ...
