Windows 7: Slow transfer rate on Wifi Lan

Slow transfer rate on Wifi Lan

Hey guys,

Maybe someone got this issue as well; I was transfering data between my old (vista 32) and my new computer (win 7 64 7100) and I got a transfer rate of 1mb/sec.

All my house is wireless and I'm used to do 5-6mb/sec between my old PC and my laptop (win XP Media Center).

I got WMP54G on the new PC and WMP54GS (S for speedbooster) on my old PC. WRT54GS for the router.

If you have any ideas / tips

Thanks!

Same Problems Too

I have the same problem, WiFi transfers between a PC and a laptop both running Win 7 RTM (legal) are slow usually lower than 1 Mbps, anyone else having this issue and any ideas on how to fix it?

Couple of things to try. First disable IPv6 support in newtork and sharing. Then turn off the RDC (remote desktop compression).

Whats the network setup like? router?, cable modem?, etc

You have to remember wireless is nothing like wired. Those bits are freely floating thought the air and are a lot more vulnerable to interference. Large continues network usage will be a lot slower then random burst. The slower the information goes the easier it is for the communicating partners to get the whole file uncorrupted.

There is also other traffic to consider, multiple data streams floating though the air can mix about and collide. You will never get substantial high-speed connections on large/long transmissions.

BTW leaving Remote Differential Compression on really is not going to effect this. It in fact can be very help when syncing files from multiple computers, RDC will only send the files that have changed. It works with DFS, and Offline Files. But it does nothing when its two computer sharing files though explorer, etc.

It might take longer, but it will get the file there with less corruption and resending of packets. In fact it might go faster if it has to only resend a few packets versus 50% of the packets normally lost.

No Improvement

I tried that and it did not help much, my transfer speeds are about 625 KBps or about 5Mbps in the previous post I meant for the b to be capital as in bytes.

My network consists of a WRT110 Linksys wireless router and a wired/wireless desktop and laptop. All machines are running windows 7.

Hi, I am so frustrated. I am running a lenovo t60 with Windows 7 x86. The wireless transfer rate is so bad. When trying to copy files from another pc I am getting transfer rate of 1mb or less/sec. When I had xp on this I had no issue. I did a clean install too. I have ddWRT linksys router. The wifi is connnected at 54mbps . I can't figure it out..tried everything....

Has anyone having this same issue able to find any solution?

Thanks.

My solution

I figured out my solution embarrassingly enough, my slow rate was due to the fact that both the desktop and the laptop were connected to the wifi, when I would connect one or the other via Ethernet to the router, my rates would jump back up.

one would think that you would only lose half the bandwidth with both devices on wifi, instead It drops way low. This might be an issue with Windows 7, I am not sure, I always had one device connected to the router when I had xp/vista.

Again, I am not sure this will solve your problem this is only what I figured out was the issue with mine.

It depend on where they are in relation to the wireless hub and to each other. I touched on this in my post above, wireless has bits flowing freeform though the air where interferences are abundant.
