Why Is My Download Speed Slow And Upload Speed High
Low Download Speed High Upload Speed Download

So I'm having this issue with the really slow download speed and very fast download speed over cable and wifi. The network topology is the following:

Oct 25, 2013 The first one is an old basic one with windows xp home 32 bit and it has a download speed of 5 mbps with an upload speed of 3 mbps My new computer has a slow downloading speed, it has windows 7 64bit ultimate, a 3.8 ghz 6 core processor, 16 gigs. Thanks - speedtest.net is the same.showing an OK download speed but timing out on the upload test. Upload is possible (as I can post here etc) but really slow. I did get a result of 22 kbps on the upload test yester. Slow upload speed but download fine.

Provider router and FO media converter (PON-TECH PT-47RW) in bridge mode =>Asus AC-RT66U router (connected to lan 1 from provider router).

The speed tests I have done are the following:

laptop connected over cable to provider router - (73.44 Mbps download / 72.83 Mbps upload) http://www.speedtest.net/result/6983140310

laptop connected over cable to my asus router - (9.36 Mbps download / 64.59 Mbps upload) http://www.speedtest.net/result/6983164758

laptop connected over wifi to my asus router - (13.19 Mbps download / 42.59 Mbps upload) http://www.speedtest.net/result/6983158870

I have already tried other suggestions from various forums like turning off the firewall or WMM but that didn't help.I have also ran the tests using an old tplink TL-WR940N router and here's what I got:

laptop connected over wifi to my tp link - (21.81 Mbps download / 10.76 Mbps uplpoad) http://www.speedtest.net/result/6983146621

laptop connected over cable to my tp link - (12.51 Mbps download / 10.65 Mbps upload) http://www.speedtest.net/result/6983153018

The download speed over wifi is slighly faster but on cable is the same...

What could the problem be?

Summary
cable provider router - 73.44 Mbps download / 72.83
cable asus router - 9.36 Mbps download / 64.59 Mbps upload
wifi asus router - 13.19 Mbps download / 42.59 Mbps upload
cable tp-link router - 21.81 Mbps download / 10.76 Mbps
wifi tp-link router - 12.51 Mbps download / 10.65 Mbps

In your ASUS Router Web Interface, under the Traffic Manager side menu item, is QoS enabled? if so, there are probably upload and download bandwidth fields. This could be the cause of your un-even throughput. Just turn off QoS on your ASUS router and run your test again. This is just an assumption because I don't have your router configuration file in front of me.

Why Is My Download Speed Slow And Upload Speed High

After trying all suggested things and setups, I asked the provider to give me the WIFI password for their device and now I am using their device's wireless network and plugged out my ASUS router.
I concluded that the router-to-router connection isn't working very well or there is some sort of limitation in their device on using another router connected the PON-TECH one.
