Internet speed 20Mb/s instead of 60Mb/s when connected through fast ethernet (100Mb/s).

Description

Hi,

My router is TP-LINK WR1043ND v1 with OpenWRT Chaos Calmer (one of the newest build). When I connect a device with fast ethernet (100Mb/s) my internet speed on that device is only 20Mb/s, when it should be 60Mb/s (according to speedtest which is correct with the speeds I'm getting in different programs). I tested that device, cables etc. and it's all fully operational. I also have an old TP-LINK device with fast ethernets and I connected it to WR1043ND and then I connected my 100Mb/s device to the that old TP-LINK and the result was identical but when I connected that old TP-LINK directly to my ISP modem the speeds where correct which led me to believe that the problem is with my WR1043ND running OpenWRT.

I believe it's a bug. If you have any suggestions or questions feel free to ask them. Also this problem was not present in the past. I don't know how long it's been present I only diagnosed this yesterday. To reproduce this problem connect a fast ethernet device to your router (preferably WR1043ND v1) running OpenWrt Chaos Calmer 15.05 (r48749) and test your internet speeds.

Yes, your right. Sorry for the duplicate. How come it was opened 3 years ago and it's still not fixed? Do you guys need some additional info?

Actually after a closer look I don't believe it's a duplicate. They are talking about a 10Mb/s connection and I don't. Also they are point out that the entire switch is slowing down to 10Mb/s and in my case it's only an internet connection (and it's slowing to 20Mb/s not 10Mb/s). I just tested their theory and my switch does not slow down to 100Mb/s when connecting a 100Mb/s device to it.

So it is my understanding that those two problems are unrelated. Please revise your statement.

It would be great if you could test some old images of openwrt with always a clean/default config.
Also a test of this openwrt fork would be interesting: http://ofmodemsandmen.com/
Please report what version give full speed and what doesnt.
At the End please test most recent DD trunk.

Thanks

Version r44952 of Barrier Breaker seems to be working OK.

Also you don't need a 100Mb/s device. A 100Mb/s will suffice.

Was anybody able to reproduce this problem?

You can close this issue now.
It's solved (kind of).
