Hello everybody,
Here is my network setup:
Downstairs: DSL 20/2 (Mb/s) line on a Fritz!Box 7360.
The Fritz!Box has a Western Digital 1TB disk on its USB port and acts as a file server and media player.
Upstairs: my desktop PC running Kubuntu 12.04.1, with a Realtek 8111/8168B Gigabit Ethernet controller on the motherboard . It is connected by Ethernet cable to an old WRT54GL(1.1) that functions as a wireless bridge using dd-wrt.
The 1TB disk is mounted over samba on the PC as such:
Code:
//fritz.box/WD-10EADSExternal-01 /mnt/samba cifs guest,_netdev 0 0
The DSL line is stable and fast, in downloads I get peaks that are over 20Mbit/sec, so over the advertised speed, uploads might get to 4Mbit/sec, double the advertised speed.
I understand the speed-limiting step in this set-up is the link between the Fritz!Box and the WRT54GL, which usually connects at 54Mb/s. I also know that it is not realistic to expect that speed on transfers. When I make backups to the disk downstairs I get a speed of about 20-25 Mbit/sec, with little fluctuation.
This is quite slow when I back up large files like films, or lots of files like photos.
Questions:
- Is this an acceptable real-world speed?
- Or is there room for tweaks to increase this speed?
- If so, how?
Other options:
I could make a wired connection to the Fritz!box, but that would involve drilling in walls and/or ceiling.
I could replace the WRT54GL with a newer and faster router that will do 802.11n, like the Linksys WRT160NL.
I experimented with a D-Link DWA-125 (USB wireless thingie) to connect wireless to the Fritz. It negotiates a 150Mbit/sec connection.
Copying a 700MB file to the disk, speed maxed out at 35Mbit/sec, but with a lot more fluctuation than when using the WRT54GL, sometimes dipping to 1.2Mbit/sec or less.
After the transfer, ifconfig told me this:
Code:
RX packets:325665 errors:0 dropped:0 overruns:0 frame:0
TX packets:566770 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:35618274 (35.6 MB) TX bytes:799416464 (799.4 MB)
No errors, but not a great speed, with a lot of fluctuation.
So a 54Mbit/sec connection gives 20Mbit/sec transfer, but a 150Mbit/sec only 35Mbit/sec. So instead of three times faster, it is only about 75% faster.
Based on this I am hesitant to invest in a faster wireless bridge.
Question:
- Would I be right in thinking a faster wireless bridge will not matter much for network transfers?
(The Internet speed is not the issue, my network transfer speed about matches what the DSL line can deliver)
