Slow file transfers? Help please - Page 2

post #11 of 16
The type of files also matter. Are you transfering lots of small files or a 1-2 large files?

i.e. It takes my networks something like 1hr to transfer 40GB of MP3s but 40s to transfer a 1GB movie.

802.11 G is 54Mbps theoretical connection.

the throughput on wireless connection in that manner is NORMALLY less than 1/2 theoretical.

now in a network consisting of multiple connection, the max transfer speed will be the slowest connection since it will be the bottleneck. (make sense?) in your case wireless G

before we being lets get this straight when noting speeds please use correct capitalization. Mbps means megabits per second. and MBps means megabytes per second. these different. 8bps = 1Bps.

anyways 1 Mbps transfer speed is very slow and something is not right here.

since you have connection at N and G you have to mixed mode, where mixed mode is normally slower.

so go in to the router and try changing Channels. since most people use the default there can be lot of interference.

If you have realtime protection try turning that off since it will try to scan everything coming in.

some routers have the signal strength control, see if you can control yours to the max.


now some reasons why even if you try to increase it, it may not change:

laptop hdds generally are 5400 rpm, this is slow.

there maybe a lot of packet loss somewhere, look at how many packets are being sent and how many are received on the other end. (wireless tends to lose more packets)

the router is just the sux.


see if this helps: even though IT SHOULD NOT.
try to do a file transfer through AIM, between your PC and your Laptop
explain AIM. the laptop is 5400rpm... dam.

I just tried connecting the lappy via CAT5 and wifi G and I still get 1 MB/s transfer speeds which means its probably not the networks problem.

Windows Vista reports the speed of the file transfer as "1.5MB/sec" in that format and all.

I have already changed the channel because I get a lot of interference on the default.

I am literally sitting 3metres above the router (1 level) but to walk down there I need 20m and I don't think the signal is that weak.

How do I check packet loss?

Lets say 8gb movies and other massively huge files. usually .7z extension.

Other times its the same files split to 700mb increments so I can shove on onto my external hard drive after they have been archived and split on my laptop (4 cores just not enough!).

Aah I love my video camera.

well as for the AIM part goes, see if you setup to do file transfer through AIM then it should be SLOWER because it uploads through the router onto the internet, goes through the AIM servers, then comes back to your internet, then through your network to your other computer. now this SHOULD be slower, but if for some odd reason it is faster than there is something wrong with your windows file transfer protocol or method.

"1.5MB/sec" is roughly equal to a throughput speed of 12 Mbps (12 megabits per second). Considering you are on 802.11G the throughput should be higher than that, BUT it could also be that since BOTH of your connections are wireless there may be a bigger slow down.

the signal strength you see in windows is not the real speed you will be getting, that is just theoretical stuff.

there are programs to monitor and show packet info but i forgot off the top of my head (wireshark will be very complicated to learn or explain), but just look in windows. goto your internet connection (view connections) then right click on your LAN connection and view status. under that should be some type of tab where you can see how many packets are sent. then goto your other computer and do the same thing there is also a place to see how many packets are received. now NOT ALL packets being sent out are going to the other computer, if your connected to instant messaging or browsing there will be more packets going out, just see if there is a SUBSTANTIAL difference.

Your running windows vista so you might wanna turn off "remote differential compression" turning that off always gives me a boost in transfer speeds screen shot below on where its at yours will be checked uncheck it and hit ok.
