I have a large[ish[ house and to provide good WiFi throughout I run two Draytek routers. The 'main' one is a Vigor 2860n which connects to the internet by FTTC, the second one is an old Vigor 2820n which has its WAN disabled and the LAN hardwired to the 2860n LAN.
Currently I'm using the same SSID on both routers, I've read quite a lot around this and the weight of opinion seems to be that using the same SSID should work OK and is more transparent to the user than using different ones. However I have also tried different SSIDs for the two routers requiring user intervention to move from one to the other, this shows the same symptoms (described below) as using the same SSID. What happens is that when I move around such that the WiFi connection should move from the 2820n to the 2860n my laptop loses its IP address. DHCP and DNS is provided by dnsmasq running on a RaspberryPi, the basic IPV4 setup is as follows:- Vigor 2860n - 192.168.1.1 Raspberry Pi - 192.168.1.2 (runs dnsmasq) Desktop 192.168.1.3 Vigor 2820n - 192.168.1.20 The Pi assigns IP addresses from 192.168.80 to 192.168.1.127 and the conf file is:- domain-needed bogus-priv expand-hosts domain=zbmc.eu dhcp-range=192.168.1.80,192.168.1.127,12h dhcp-option=3,192.168.1.1 local=/zbmc.eu/ cname=bbb,beaglebone cname=mx201,maxine-X201 cname=ben,DESKTOP-978VD5M cname=oki,MC342-AE529C dhcp-host=00:BB:3A:E9:A3:15,maxineKindle dhcp-host=00:09:B0:C9:CE:81,onkyoTx-nr616 dhcp-host=28:EF:01:2D:EB:07,chrisKindle dhcp-host=08:EB:74:9D:47:53,humaxFreeview dhcp-host=2C:08:8C:CC:9A:9E,humaxYouview dhcp-host=00:1F:E2:4E:8F:CA,maxineStudy dhcp-host=00:25:36:AE:52:9C,192.168.1.50 My laptop seems to lose its IP address whenever I move from one Draytek's WiFi to the other but only when the IP is assigned by dnsmasq. If I connect to my guest network (192.168.6.x) then I get a IP address assigned by the 2860n and a good connection to the outside world. If I then reconnect to the 'local' WiFi the laptop loses its IP address. It's as if dnsmasq doesn't see the disconnection and doesn't answer the new DHCP broadcast from my laptop. If I leave it disconnected for a minute or two and then re-connect to the WiFi it *does* get an IP. Can anyone explain what might be wrong and/or a fix or workaround? -- Chris Green _______________________________________________ Dnsmasq-discuss mailing list Dnsmasqemail@example.com http://lists.thekelleys.org.uk/mailman/listinfo/dnsmasq-discuss
