<p>Ok, I'll try and keep this as short as possible. I have a Motorola sbg6580 gateway from Brighthouse. From the gateway I have connections to my gaming PC, WAP, Switch to htpc and hdhomerun prime, and a switch to Xbox 360 and PS3. A few times a day, 2 or 3, all my devices lose connectivity briefly(about 15 seconds). I have static IP's for all of the HTPC gear, Xbox included because I use it only as an extender. I was thinking that it has to do with the DHCP leases expiring so I raised them to 24 hours, but its still happening. I have been talking to the lead Brighthouse tech and he seems stumped too. WAF is dropping every time the connection drops so it's getting to be a real pain in the ass. Any ideas would be great. Just to be clear, its the internal network that is dropping...WAP, Xbox 360, Tuner, and HTPC. The internet connection seems to stay up the whole time.</p>

Also, does anyone have any idea on how to get WMC to resume recording after a connection loss.
 
If you can try running wireshark to see if you can capture whats going on when you get the meltdown, it might help track down the culprit.
 
Did that, unfortunately nothing out of the ordinary happens. Everything is going along fine, then everything just drops, about 15 seconds later traffic lights up with all devices trying to reacquire connections.
 
Could be a switch close to death.

I have had some switches do odd things on their way out.
 
I'm going to bridge the gateway and try my own router, that would be the only common switch that they are all connected to.
 
Are your static IP's outside the DHCP range configured in your router (or DHCP server)?
 
Have you tried removing the static IP's and see if that makes a difference? And are your static IP's assigned on the device ends or are you using a DHCP client reservation list?

Is it possible your gateway is getting rebooted for some reason? Not much help here, but just thinking out loud...
 
Assuming at least some of your devices are wired and they drop too, your switch (be it standalone or built into a router) is the only likely culprit, unless every single device and/or cable has an issue.
 
Everything was using dynamic IP's, I changed them to static to try and fix the problem. All static IP's are done on the devices themselves, except my wife's windows phone 8, apparently you cant set static IP's on windows phones. The gateway is not rebooting, all the lights stay lit up. Everything is wired besides our tablets and cellphones. I tried bridging the gateway to bypass the switch on it, but im still getting the same issues. I'm completely fucking stumped.
 
I suppose one easy but potentially annoying procedure to do if you've tried multiple switches is disconnect a device or two from the network for a while, see if things still mess up, if so, plug them back in and try unplugging something else until you find it.

You could try running a packet sniffer on one of your machines and try to capture activity around the times of the dropouts. I use Wireshark for some stuff, though I haven't tried it to diagnose this specific problem, not sure if there may be a better choice.
 
Ok so 15 second drops of connectivity usually points to a gateway issue or a ip address conflict.

Easiest thing to do is build back you network to bare minimum and build it back up , also for arguments sake changes you wireless channel , not sure in a how busy of a neighborhood you live but it cant hurt.

Then there are the obvious issues , you got pets ? , check your cables for damage. As mentioned before dying hardware , regretful to say SoHo hardware dies without and good indicator of something being wrong.

ALl that said my money is on the 2 first items OR a misconfigured system causing the first issue (had any new software or software updates ?)
 
Rebuilt the entire network, reset router and all configurable network gear to factory defaults and started again. All cables are concealed, plus my dog doesn't chew on anything. DHCP range starts at 20. All configurable devices have addresses under 20. I am sitting on channel 6 for wireless, everything around me is on channel 1 and 11. Theoretically everything should be working, but I'm still getting drops in connectivity. I went ahead and ordered a Motorola sb6141, and Asus rt-ac66u so I can ditch the provided gateway and eliminate that as a problem completely. If that's not the problem then I dunno wtf is.
 
That's the first thing I tried after i went through the basic troubleshooting steps. Doesn't make a difference...at least with the problem I'm having.
