The title was the best way I can describe this painful ongoing issue that has persisted through several tech visits and two different modems, though the problem has changed slightly over the year and a half or so we've had it, it still persists and emerges in a more annoying manner
Here in Navarre, FL, Whenever I download something, be it youtube, netflix, a game on Steam, whatever the case may be, when the internet is being used, the latency shoots up, and packet loss is heavy. Start a download, 300 to 700 ping, to anywhere, lots of timing out, and eventually the upstream light on the modem starts blinking until you hard reset it, download or no. Online gaming becomes impossible if a download is also taking place. Before I had this modem, I had a Motorola modem. While downloading with that modem, everything was fine but the connection would just cut out completely, and the Upstream light would blink, then a few seconds later, the internet would resume being fine again, and the light would return solid. And that would happen every couple of minutes throughout a download. Occasionally the modem would fail to resume working and hard reset itself. This current modem did the same thing when I got it, even with new connectors, lines, and making sure everything was in working order, and a couple of months ago during a service outage, it stopped doing that, only to do what I'm describing now
The heavier the load on the internet, the worse this gets. This means simply watching youtube will turn someone's game into an unplayable lagfest, or the very small usage that being connected to an online game server will even affect it and cause higher than normal packet loss and latency
This happens both with, and without the router. I have absolutely ruled out the router as being the issue. PC hooked straight into the modem and the exact same problem happens with no change.
During a download, and the problem, my Signal to noise ratio and power levels remain the exact same as when I'm not using the internet at all and the internet is working normally
DownStream:
Power level: 6dBmV
SNR: 37dBmV
Upstream:
Power level: 45dBmV
The modem in question is an RCA DHG536.
Firmware info:
Software Build and Revisions
Firmware Name DHG536-75.01.12-081023-S-1C1.bin
Firmware Build Time 11:55:35 Thu Oct 23 2008
Speeds are 35Mb Down and 5Mb up, which I do get, but this isn't an issue with the speed, but consistency and stability
I can sit here and ping anything and it'll work perfectly fine and drop maybe one out of every 50 requests, which at this point would be extremely acceptable, but as soon as I start using my internet, the ping skyrockets to 300 all the way up to 700 in some cases, and times out often. As I said this happens with a router, and without a router. No uploading is taking place (At least no more than would be during a single file download off a single server)
Here's two tests done at pingtest.net, the first image shows what it looks like when I would just simply be browsing the internet, and the second was done with one download running (Steam) and the Power Levels were right on point with where they should be (Listed above) During both tests

I'm on Windows 7 64bit, I have even updated my NIC drivers to the latest version, though this problem also happens through multiple machines, even a Playstation
Tech support only wants to send people out and even said there was no problem when I was showing over a 700ms ping while talking to them. The techs have not yielded any results the last 3 times they came out over the 18 months, and they did EVERYTHING that they possibly could. And I have yet another coming in a couple days to take yet another look, but I was hoping someone could shed some more light or info about this, and if they had the same problem I'm having, and any other ideas
Cheers
