Hello,

My Slingbox classic was working fine until I added a second wireless network at my house.

Here's the original set-up:

cable modem
D-Link DL-524 wireless router
Netgear WGE111 wireless game adapter
Slingbox classic

Added DSL line:

DSL modem
Linksys WRT54G

Would like to continue using the cable modem original network, since that has a higher upload speed. Since adding the DSL network, the Slingbox doesn't work.

Here's the ip info:

cable modem/D-Link
ip=192.168.0.5
subnet mask=255.255.255.0
gateway=192.168.0.1

DSL mode/Linksys
ip=192.168.1.100
subnet mask=255.255.255.0
gateway=192.168.1.1

Is there a conflict due to both networks having the same subnet mask of 255.255.255.0??

Would changing the subnet mask of the DSL network fix my problem??

Any help would be greatly appreciated, since I'm awaiting a reply from Slingmedia tech support.

Thanks...

My first thought is to make sure your gaming adapter is not trying to connect with your Linksys router.

If you don't need wireless on the linksys, turn it off. If you do, make sure it is on a different channel than the D-Link.

There are 11 possible WiFi channels - 1 through 11.  Just about every router defaults to 6.  Only three of the channels are non-overlapping - 1, 6, and 11.  You probably have two routers on channel 6, which is going to cause mutual interference and automatically reduce your network performance.

Try setting one to channel 1 and the other to channel 11 (it should be in the router config, somewhere).

And no, the subnet mask has nothing to do with it.  In fact, if the mask were different it could be worse.  (I can explain how IP addresses and subnet masks work if you'd like.)

shanks909, are the two routers linked in any way? if not, I would go with MegaZone's advice. If yes, I would make sure the slingbox is still picking it's IP from the proper DHCP server - turn off new router, power cycle the slingbox, and test. If all is OK, turn back on new router, it should continue to work. If not, you definitely have MAJOR interference.

Good luck.

Thanks for the advice guys. I did change the subnet, and as expected...no change! I'll try the other suggestions when I get home tonite. I know that the old router is on channel 10, and the new one is using channel 6.

 

BTW...got email back from Sling support yesterday. Their advice....reboot the Slingbox. Gee thanks, that's about as useful as a chocolate teapot!!

10 and 6 will overlap - 1 and 11 are best for frequency separation, but 6 and 11 would be non-conflicting too.

IP addresses are really 32-bit values. For human readability they're broken into 4-octets, 8-bit chunks. And 8 bits can specify values form 0 to 255. Hence the 'dotted quad' IP address format. 255 is 11111111, 0 is 00000000 - huzzuh binary. ;-)

Now, to route traffic, devices need to know which part of the address is the network and which specifies a specific host. That's where the subnet mask comes in, it is a 32-bit 'mask' applied to the address. So a subnet mask of 255.255.255.0 means the first 24 bits are network and the last 8 bits are host.

In your case, one network is them 192.168.0 and the other is 192.168.1, with up to 256 host addresses. Really, 254, because high and low (0 and 255) are reserved for broadcast traffic.

A simple test to see if it is interference would be to just turn off the router the SB isn't connected to. If the SB starts working well, it is almost certainly interference.

Thanks again!! I turned off the new (linksys) router, and restarted the game adapter and slingbox. Everything works fine, except I had to go through the sling set-up again, since I had reset the box to factory defaults.

I then plugged the power back in to the linksys router, and everything is still working.

Tomorrow, I'll probably change the channel on my original (D-Link) router to 11, and then I'll be using 6 & 11, so hopefully no conflict.

 Thanks once again for your assistance.
