Network crippled when downloading

X82 · 22 Sep 2012 at 21:48

I bought a brand new Asus RT-N66U (VER.B1).
If I am downloading at say between 6-8 MB/s my entire network grinds to a halt. For example, my girlfriends connection on her laptop via wireless drops quite a bit. Youtube videos take ages to even buffer the first few seconds and if I load up a game to play online and try the server browser, the pings range from 150 to 250.
But the second I stop the download, pings go to normal, 22-29 and everything works normally. This never happened to my previous router. I paid a lot of money for this router and its features and so far my network feels worse off as a result. Any ideas?

Below is my speed test results when downloading

And here is my result as soon as I stop the download (which is running at 3.2 MB/s, not anywhere near close to max)

If you are downloading at 6-8MB/s then you are probably saturating your download bandwidth and limiting other traffic. This is quite normal. Maybe look at limiting your download speed so other things get some of the bandwidth.

Your connection can only handle so much

Also if you are using bittorrent then you gotta set up your port forwarding

The thing is, I never had this problem on my previous router. I could download at 4-6MB/s while still play BF3, and the misses watches youtube on the laptop.

I have a 100 meg connection, so I thought I would have plenty to go around.

You've saturated your upload ... Fix your torrents mate .... Leech more than you share - I only give away 1K/s and limit the total number of connections. SSL them if you can also

WIFI or wired?

X82 · 22 Sep 2012 at 23:29

Wired for me, wifi for the laptop, and I'm not downloading torrents. Happens if I download a game on steam thats like 5gb or origin game etc. No torrents at all.

Should have stuck with the awesome superhub then

Seems to be JDownloader throttling the hell out of my connection. No idea how to fix that, but I guess that's my problem.

How many threads is it using?

I had a similar problem, twice, with a Linksys x3000. Ended up RMAing it as Linksys support had no idea what they were doing.

Don't do this. It completely goes against the idea of torrents.

Limit your upload yes but not to something stupid like 1kb/s

What firmware are you running ? It changes quite often for the RT-N66U (latest is x.220 from memory).

The router also has QoS built in, so you should be able to prioritise traffic, which would let you surf and game as a priority over P2P for example.

The router also has a torrent client built in (Download Master), however I've never managed to get that to work :-)

Which is why this stuff should have always remained on usenet.

With all the noobs ******* up the networks for everyone I'm not particularly a great fan of p2p

Quality noob comment about noobs.

Why not use QoS to prioritise your gaming or youtube streaming. You can set this up in the router menu. You will probably find asus have preset it to put downloads above all else.
