Need help with networking issue

Here's the setup. I have a media center laptop running Windows 7 HP. It has a hardwired network connection ( on board gig Ethernet) that is connected to internet router (all devices work on this router). IP is in the 192.168.1.x range. Then I have another network connection that is via a USB network adapter that is on a non internet network via a private router that connects the laptop to 3 silicon dust HD homeruns. This network is on the 192.168.6.x range.

Here's the issue. For some reason I can ping anything I want on the internet but no applications ( browser, media center, windows update etc) can resolve the internet traffic. Any ideas?
 
Ping is a tool to check that your were able to reach the destination computer. if you want application to be browse, then you need check DNS is working fine.
Client computers should resolve the request via DNS.

You are on different subnets, so normally, no, they can't 'talk' to each other.
Is there any reason why you have them on different subnets ?

There are ways to fix this, but, might as well start at the beginning. 🙂
 
I don't want the different networks to talk to each other. I want the media center laptop to be able to use both networks independently. The 192.168.1.x network for internet and the 192.168.6.x for the tuners. The reason I'm doing this is that my parent's house only has 100mb networking and if you have all four tuners streaming simultaneously that is somewhere around 80mb just from the tuners and that network would get saturated. So I'm running two independent networks.

Are you connecting the laptop via wireless or wired ?
You can manually set the gateway & IP of the laptop to the network you want, but, that isn't fun to switch it all the time.
Why don't you just get a gigabit switch, stick the tuners on that, and from the switch to the recording machine & the router. As long as the recording machine has a gigabit NIC, you should be good to go.

That's what I was going to suggest -- get a gigabit switch. I did this some years back, when our internet router only sported a 10/100 switch. And as far as I know, CAT-5 cabling should be fine with it: my bro' installed our cable drops back in '01 . . .

I, too, have (one) HDHomeRun Prime. I'd been debating whether to get a second tuner, but the fam-damn-ily doesn't care if they can watch TV on their PCs, or they'd just as rather use the provider's cable-box. One of my three tuners had been allocated to Mom's computer, so when I discovered she doesn't use it, I "took it back." I'm just a bit surprised that someone would need nine tuners! That's a helluva Media PC!! Definitely -- get a gigabit switch for your "special" subnet. That's what I say.
 
This is 3 of the non prime models so 6 tuners. Only need that many to deal with back to back shows on different channels with overlap. If only media center would allow tuner sharing for recordings!
 
BTW, don't know if this is widely known or not, but, if you are recording QAM, chances are, you can use 1 tuner for multiple channels, if you use software that is aware, like mythtv, or npvr.
I am using a HDhomerun prime as well (QAM only right now), and I can record 4 channels from 1 tuner.
Media center can't do it the last time I checked...
 
This is atsc so no help there but thanks 🙂

Also that is only for channels they pack in the same qam channel but chances are they don't pack multiple HD channels in each and who records SD these days? 😉

Actually, these are all in HD. To be specific, 2 were in 1080, 2 were 720 from 1 tuner. Each multiplex can hold up to 95Mb/s, so that is plenty for a few 1080 streams.
Sorry for going OT.
