Hello,
I bought a d-link dir-655 (gigabit) router a few days ago. I connected it and I got it to work pretty quickly, however LAN-speed is a bit disappointing. I can't seem to get more then 6-8 MB / second, wheverever I copy files (see below for devices connected).
This happens when copying large files (500+ Megabyte) with total commander or flashFxp (ftp-client).
The router is connected to 4 devices
- PC A with GBit Intel Pro 1000ct network card (reported under winxp as being "1Gpbs - connected)
- PC B with GBit Intel Pro 1000gt network card (reported under winxp as "1Gbps - connected)
- QNap 209 NAS (with 1GBit connection)
- Buffalo Linkstation D300GL (should also have Gbit connection, lighting blue which means gbit connected)
When doing a ping from PC A to PC B, it's with a reply <1ms ttl=128.
I had cat5/cat5e cables (not entirely sure which it was), so I went and got cat6 cables (since they should definately support GBit connections).
However that didn't increase the speed either, and I'm at a loss... Why do I only get 5-6MB/sec?
From browsing through the QNap forums I read that 20MB/sec can be expected - but I'm far from that. At work when copying files with GBit ethernet, I get 30MB/sec.
Update: I tested using IPerf with the following two batch-files
server: iperf -s -u -w2m -i1
client: iperf -c 192.168.1.7 -u -b400M -w2m -i1 -t60
result on client: [1920] 0.0- 1.0 sec 5.46 MBytes 45.8 Mbits/sec...
Shouldn't it more be like 600-700Mbit/second (1000 would be theoretical max, which probably cannot be reached)
Does anyone have suggestions what to try now?
