I have a linksys WRT54G with 2 LAN pc's and 1 wireless laptop. My issue is the slow (I mean slow) file transfer from Lan to wireless or vice versa. I have no issue with slow file transfer when sending LAN to LAN. Is this an issue with the WRT54G or is the setting tweaks that can be adjusted to optimize transfer speeds?
XP Home on the Desktops (LAN) and XP Pro on the laptop (WLAN) We all know that 802.11G is 11-54Mbps and I'm getting nowhere near that

When I have encryption enabled, my WLAN internet download speed is 44KB/sec and if I disable encrypion, I can get 202KB; I get 700KB/sec on LAN.

PS I have a Belkin F5D7010 Wireless-G net card

You should get about 10Mbps or 1200KB/sec.

Did you check the usual stuff:
1. Signal strength in %
2. Are youe wifi on a channel ( 3 or 7 ) that has too many people ?
3. XP SP2 slowing you down.

Signal strength is "Excellent"
This is a wireless connection at my home (linksys WRT54G channel 6)
I am running xp pro SP2. Is there a tweak for this?

What kind of wireless card or built-in?

Is teh computer fast enough and have enough memory?

The Slowdown when encryption is a is a clue that needs checking into.

Normally at work the laptops we are working on download updates speedily via the wireless. Everynow and then one of them just chugs. Usually one with a slower processor and and/or only 256 Mb memory where things are always swapping to the hard drive.

Belkin F5D7010 Wireless-G net card
intel pentium M 1.6GHz 512RAM

Is there an app that will monitor network file transfer speed?

Task Manager has a network bandwidth graph.

Yeah, but it doesn't give an exact file transfer speed

You can enable more fields with View -> Select Columns. That will get you bytes/interval but it's not clear exactly what the interval is (it's each refresh of the graph, but graph update speed is specified by "fast", "normal", etc.)

Windows' maintains a lot of performance counters you can view with System Monitor:

You may just have a hardware problem. But I'd check the settings issues in XP first (I have zero recommendations for that); maybe turn the router off for a few hours and re-start it.

I had the same router once - maybe not the same version - and it was crap. I had to toss it within one month due to poor connectivity. But, I've seen others on this forum that loved them.

OK, I that I might solve the problem if I get a Wireless N router and adapter card. I got a Linksys WRT310 Wireless N Gigabit router and a Linksys WPC300N 802.11N adapter. With encryption enabled and disabled, I can only get 19KB/sec internet download and 1Hr to transfer a 30MB file from LAN to WLAN. Signal strength is excellent with both routers so thats not the issue; it must be some setting or something, I just don't know what it could be.

Some things to try...
I assume you have the WAN side connected to your internet connection, disconnect it and try your transfer. If you see improvement you may be harboring a virus/trojan/malware. If there is no improvement, leave the internet disconnected and disable any active AV or Spyware/Malware detection software on both computers and try again. You could also try installing SP3.

Got everything up with normal speed. What I did was disable ssid broadcasting, set my adapter card to tkip (it was at AES). Now what is AES and how why, if it does, affect my network? I know what ssid broadcast does, but if a neighbor was connecting to my network, wouldn't it affect my LAN internet speed as well as my WLAN? In my case, my WLAN was being affected but I had no issues with my LAN.

if you haven't been checking your router logs you won't know how many others have been using your connection. of course someone using your wlan uses up the bandwidth of the router and slows everything down.

AES is just another form of encryption.
http://en.wikipedia.org/wiki/Advanced_Encryption_Standard

If your neighbor was connecting to your network unless he was downloading files from your wlan you probably wouldn't notice him on the lan side of your network. But if he's downloading large files or such you probably would notice a decrease in download throughput. Several issues can affect wireless network connectivity. Walls, Distance from wap to wireless device even microwaves. (*Yes i learned that last one the hard way.) good to hear you got your network back up to speed.

What version is your router? If its one of the versions that can be flashed with different firmware, you may want to take a look at doing that. I did it to my wrt54g v3.1 and it did help with my overall performance. I flashed Tomato to mine.

AES is a very popular form of hardware encryption ( that are about 7 sub-types ), you should turn it on, so your neighbour can't look into your folder on your computer, since all computers on the same un-encrypted wi-fi server will be on the same network.
