I presently have two wi-fi adapters running on my laptop.

  • The one with the highest priority is connected to my phone's wi-fi tethering, and I've been assigned a dynamic IP address usually around 192.168.43.5. (IP address and subnet configuration can't be changed, because it's an unrooted phone.)
  • My second network is a LAN exclusively. Right now it's running with a subnet mask of 255.0.0.0 (my best guess) and a default gateway of 10.0.0.1.

Unfortunately, sometimes my phone will redirect to an image compression service hosted at 1.1.1.1 or 1.1.1.2. When this happens, images will fail to load on some websites. When I attempt to open the images, I'm taken to my LAN router's configuration page, hosted at 10.0.0.1.

Something is amok here. How do I set up my LAN router's IP address assignment and subnet mask to keep from interfering with my wi-fi hotspot? There's precious little information about it online, even when I search for info about private subnet masks.

My local network config is as follows:

Wireless LAN adapter Wi-Fi:

   Connection-specific DNS Suffix  . :
   Link-local IPv6 Address . . . . . : fe80::d4d6:b65b:6db4:9630%12
   IPv4 Address. . . . . . . . . . . : 192.168.43.5
   Subnet Mask . . . . . . . . . . . : 255.255.255.0
   Default Gateway . . . . . . . . . : 192.168.43.1

Wireless LAN adapter Wi-Fi 2:

   Connection-specific DNS Suffix  . : Belkin
   Link-local IPv6 Address . . . . . : fe80::44e5:80c3:809e:2055%40
   IPv4 Address. . . . . . . . . . . : 10.0.0.2
   Subnet Mask . . . . . . . . . . . : 255.0.0.0
   Default Gateway . . . . . . . . . : 10.0.0.1

When loading images, often my URLs look like this:

1.1.1.2/bmi/readwrite.com/files/styles/630_0su/public/fields/shutterstock_118925992.jpg

A tracert to it yields the following (it goes to the wrong, local, router:

Tracing route to 1.1.1.2 over a maximum of 30 hops

  1     2 ms     1 ms     1 ms  router.belkin [10.0.0.1]
  2  router.belkin [10.0.0.1]  reports: Destination net unreachable.

based on what you are describing, somthing is misconfigured. could you please post the IP configuration for both interfaces of your LAN router? if you nslookup or dig the domain name where the images are hosted, what server responds and with what IP? –  Frank Thomas Oct 10 '13 at 4:17
    
@FrankThomas Adding them shortly -- but the images are hosted at 1.1.1.1/bmi/[remote/location/of/file/here] ... details to follow. –  David Is Not Here Oct 10 '13 at 4:30
    
if you are accessing the server by IP address, that implies it must be a routing issue then, and your tracert backs that up. whats the output of route print on your laptop? –  Frank Thomas Oct 10 '13 at 4:38
    
@FrankThomas Thanks for the input; I couldn't deduce anything about this specific address in "route print" so I left it for you in its entirety. 192.168... is presumably the wi-fi hotspot, 10.0... should be the LAN. –  David Is Not Here Oct 10 '13 at 4:44

it shows you have two routes to 0.0.0.0 with the same metric, one for each nic, so windows can't decide which interface to use. you can try route delete 0.0.0.0 to remove one of them, and see if it fixes the issue temporarilly, but I can't guarantee that it will delete the right one (10.0.0.2). do you have Adobe CS3 installed or somthing else that uses the bonjour service (iTunes mayhap)? social.technet.microsoft.com/Forums/windows/en-US/… –  Frank Thomas Oct 10 '13 at 4:58

You must delete both default routes, then re-establish the one you want (via 192.168.43.1) as the "sole" default gateway. From a Terminal, type:

route delete 0.0.0.0
route delete 0.0.0.0
route add 0.0.0.0 mask 0.0.0.0 192.168.43.1 metric 1

To make this permanent, replace in the last command route with route -p

Success! Only one "route delete" worked, but as of now there is an active route and a persistent route both connecting the address 0.0.0.0, with the netmask 0.0.0.0, to 192.168.43.1, as it should be. All is well in the world. –  David Is Not Here Oct 11 '13 at 1:15
