Hi all! I have an annoying problem and I hope to get some advice. Currently I am using my Airport Extreme in bridge mode plugged after my ISPs modem/router. DHCP is handled by my ISPs modem/router (which is Thomson TG789vn). However, it has a strange problem/defect: if a device leaves a wireless network (e.g. phone or notebook) when it comes back it always connects, but sometimes will not have any Internet access. Reconnecting several times and/or providing it with a permanent IP on the network usually helps, but not for long. With no Internet access the devices are still visible on the local network and I can browse their content if I wish. It is interesting that absolutely no problems arise in case of wired LAN connection, even if the client device is switched off for some time and then switched back on it just works as supposed to. I figure it is a DNS problem of the ISPs modem/router (some sort of bug in the firmware maybe), but my ISP will not recognize the problem and even worse the issue persists after replacement of ISPs router/modem. I live in the countryside and do not get to choose between ISPs, so I am stuck with this one. My idea was to try and make Airport Extreme a DHCP/DNS server for my network, but I am not sure how to do that. Essentially I want to build a chain with two routers: ISPs router/modem provides IP address and DNS to my Airport Extreme, and Airport Extreme in turn provides IP addresses and DNS to all other devices on the network. Can I do that? If yes, please briefly explain how to set up my Airport Extreme accordingly. Many thanks in advance!
