Posted: Thu Feb 14, 2008 19:38 Post subject: slow transfer rate
I have a fonera with DD-WRT v24 RC-3 (09/13/07) std connected in bridge mode with my wifi router. When I try to transfer something from my pc to the one connected to llafonera, the trasnfer reach 40 kb/sec max! I think there is something wrong with the fonera, or the linux machine that receive the file. In both case can you help me? The network card is recognized by the system but maybe something is wrong with the driver (i'm using ubuntu) but when I donwload something from internet I reach the top adsl speed and via cable too!Via cable I reach 10/100mbit...so i think there is something wrong with the fonera...can you please help me?
I found a problem....the trasnfer of the ftp was limited by the server to 40kbit...so i removed it, but the transfer is still low....800kb-1mb approx...in conclusion, the network card or driver in linux or windows are fine, the signal is good (87% in this test) so it's a fonera problem....any ideas?

maybe the receiver is overpowered. how much is the snr? >50db?
everything above 25-28db will end up in a 54mbit rate. but to much will decrease troughput _________________ Forum Guidelines...How to get help

in my case, if i connect router and fon directly, the max connection is only around 800kbps, and with switch in between it can reach more than 5mbps...
Dunno if it works. Actually I tried the fonera in client mode and in AP mode, and in both modes I get a throughput of around 1Mbyte/s, that's around 8 megabit/s.
Also I noticed that, while i'm transferring large files, cpu load goes up to 1.50/1.70. Maybe there's something wrong with the the interrupt handler or so...

you are talking about a wifi switch or cabled swtich?
You should try using channel 1. I was getting crappy speedy with other channel for some unknown reasons. I was using rc6.2. I max out at 41% of 54mbps or 22mbps.
I glad to see that someone is getting full speed out of this hardware. Actually I connect my fonera to a dg834g (which has an integrated 4 port fast ethernet switch) and I'm still getting 8 Mbps (around 1000 kbyte/s) throughput in AP mode :/
I put original fonera firmware with same network topology and magically throughput went up and reached 22 Mbps, exactly the same amount the dg834g is able to give too.
I tried also dd-wrt in client mode, so with ethernet directly connected to a fast ethernet card (realtek based), and again 8 Mbps throughput :/
I'll try with another switch between the fonera and the router and I will post the result.
Can you both say us the name and the model of the chipset inside your switches?
my switch is part of the router. my router is wrc-1000. It's an old wireless(802.11b) router w/ 4 port network. Ya, my rate was transfering a 300MB file between 2 computers. I was getting shitty speed at all other channel except channel 1. You should try to use only 1, 6, and 11 too. I hope that help. My setup is a computer--cat5e-->router--cat5e-->fon--wireless-->labtop. _________________ x1 Fonera 2100 RC6.2

x2 Fonera 2100 DEAD! I dled a 1kb redboot and flashed it. Redboot was dead for sure. Tried to hotswap flash. Now of both them are dead.

in my case, if i only use the router inside my adsl modem (CopperJet 816 RouterPlus has a router inside for sure) the speed was drop, no matter what channel that i use.
and then i read someone mention about using external switch in fon forum, so i give it a shot, and i can get my full speed back.
about the external switch that i use, i am not so sure what is the chipset inside, i just take the cheapest one when i bought it. the type is Asus GigaX 1005 Desktop Switch 10/100.
so my configuration is: internet line -(cable)- adsl modem -(cable)- external switch -(cable)- fonera -(wlan)- laptop.
i also try to use original fonera firmware without using external switch, and the speed that i get is around 2500 kbps, and with external switch i can get my full speed.
