This might be better suited to the Computer Issues thread, but I am fairly certain this has nothing to do with the actual PC's involved.
The house in which I live was built in the 50's, it has pretty ancient electrical and cable wiring that's never been replaced as far as I know. I have a pretty basic broadband cable connection, but not unreasonable dl/ul limitations. I know that's not the issue I'm dealing with.
I absolutely cannot efficiently and consistently carry on streaming voice communications and multiplayer games. Teamspeak, League of Legends, Dota, DayZ, etc. All are unplayable. Majority of tests turn up between 25-28% packet loss. I have complained to the local ISP, and they came and replaced every connection coming to the house and buried all the cables. The official word was that we had suffered critical squirrel chewing damage to the cable lines.
All cables from the ISP to the house have now been replaced and buried, but the problem persists. I'll detail to you just how horrible it is here: the lines run to the side of the house, to a splitter, which then loops around to the house, which then cuts through a hole in the wall directly to the modem and router running the entire network. Yes. There is actually a hole in the wall that admits a cable and is basically just a circular cut in the house. You can look through the motherfucker. The cable from the splitter that connects to the new cable line that has been recently been attached to the house just fucking shoots through the goddamned hole in the wall.
I know this sounds absolutely ridiculous, but I'm a newcomer to this piece of property. I didn't design any of this or intend for it to be this way. Some fucker years ago fucked this together whenever broadband made it to this area, and now I have to deal with it.
I have absolutely no experience with this sort of thing other than knowing that if your cables are fucked, you replace them, and if your router is fucked you unfuck it, primarily by unplugging it and plugging it back in. More than anything, I have no experience battling squirrels that have seemingly devoured every connection to the house. I didn't know it when I got the motherfucker, but apparently they are voracious and have killed off cables for goddamn near two decades.
Interesting fact: the house next door, which was owned by the same family until the last year, has absolutely pristine connection quality. I ran in with a laptop, did a test wireless via pingtest, then tried out TS and a brief session on DayZ, BF4, and PA. Completely fine. That house was built in the fucking 20's.
So, the cables running to the house are brand new, and go to a shitty Walmart level splitter which further goes to god knows how old cable lines that run outside, around the wall, through a goddamned hole in the wall exposed in the wall, to the main PC that is connected to the modem and router.
Should I just replace the cables, or should I just murder everyone involved and blow my head off while I dive into a deep river?
