So downloading anything makes online games unplayable.

It seems that if I am using anywhere from 10-50% of my bandwidth, my latency in online games shoots really high. any ideas? I have 45Mbit down, rarly does a single transfer get much above 25Mbit.

Without knowing more about your network it's hard to be sure. One possible culprit is that your router isn't keeping up as well as it should if it has the bandwidth available. It also depends on how many other devices are hooked into it. Even if they aren't being utilized they're still putting a small load on the router.

It is an asus RT-N56U. The stat page usually list its memory as half full but it is rarly using much cpu. I think i've only seen any significant cpu use when there is local network file copying, esp from the network drive.

That router should have sufficient CPU to download a file and play a game at the same time at least as long as there isn't too much going on the network otherwise. Is your PC hooked in wired or wireless? And how much of a jump in latency are we talking?

Did you enable the "QoS" function on that router? I have an RT-AC66U, and had similar trouble with online games while somebody else in the house was using Netflix, but that cleared it up. I guess it prioritizes certain types of traffic over Netflix, and the video player buffering takes care of the rest. I'd assume it would be similar with downloading files.

You aren't using BitTorrent, are you? It eats routers.

Also, it could just be your ISP sucking.

it is the only wired connect. It will quickly bounce between 1-1000ms delay in online actions. nothing else is using the wireless network currently in the house.

Dave, I do currently have the QoS on, I was attempting to stream some video to chromecast while there was a 10Mbyte download going on (torrent, was time to update mame) and it was having none of it so I was playing with it then. The current download was from an installer program and was probably using one of the common http ports. I do not believe it used bittorrent cause if it did it should have netted 10mbyte as well.

ISP connections don't lag up just cause I am downloading at 1-5mbytes a second. -_- I am thinking it is more local and is maybe an issue with the built in lan adapter.

Downloading anything while playing a game has always caused lag i my past, no matter the setup.

Just my two cents.

torrent =/= "downloading" !

You are downloading AND uploading. Set an upload speed cap.

I have one of those. It completely craps itself doing anything at the same time as gaming.

it's not just that.

(here i go and make it obvious that i do not know anything about computers)

you are constantly chatting with thousand of clients; asking them "can i have 1 more block of data pls?"
this kind of work is coded to be one part of the work of the pc. and the networking that you game wants to do, is thrown is with the same work as the torrent, and as it's just one job out of thousands, it takes a few extra milliseconds each time to be processed.
( imagine this was actually done to make your pc work better, and it's not a bad idea)

you could set up your system so that the two are separate.. i guess. i have no idea how.

I'll bet that his service has something to do with it as well as time of day and, if on cable, how many other people in his area are doing the same thing at the same time.

Puff, the amount of data on my node would make my bouncy 1-5Mb transfer a drop in the bucket and I would be seeing increased ping times regardless of what I was doing. That however isn't the case.

I've never been able to attribute issues to my neighborhood traffic, it seems we have got plenty of bandwidth on my loop.

Haven't been able to do more trouble shooting, I need to see if gaming lags when another computer is saturating %50 of the connection.

Read my post above. Your problem is not the download speeds, its the saturation of your upload bandwidth. Set an upload cap to stop that from happening. You will have to play with the cap levels to see what works for yours. You may want to start at 50% or less of your actual maximum upload speed.

There is also a factor called the ISP.

The general demand for Bandwitdh Grew in folds with time. The infrastructure (like all other infrastrucure in the USA) is Not growing in Tandem.

So IPs use different Algorithms for throttling Re-Routing etc. to compensate and maintain their High Revenue.

Those manipulation do Not kick in when One is involved in simple Browsing tasks. They do kick in when downloading and streaming.
