Slow transfer rate on Wifi Lan

[Mercador]

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

Remote DIFFERENTIAL compression

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 Win7 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 Win7, 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.

I subscribe to a tech letter called 'Windows Secrets' and in this week's edition one of the editors wrote about a test he tried as he had this problem occasionally and knew lots of people who also suffered from slowdowns on their wifi transmissions. He turned off the Windows HomeGroup (which you'll find in the Networking section of your Control Panel and is enabled by default) and slowed down the encryption from 128 bits to 56. Instant fix! In other words he just reverted to the classic network group and what is the standard level of encryption for XP users and that has solved the problem consistently for him. Highly recommend Windows Secrets for Windows users, by the way - I've learnt all kinds of useful tips over the years and I'm not particularly techie. Anyhow, spread the word and hopefully MS will stop HomeGroup being such a resource hog in some future Service Pack!

And here is the link to that article:
Simple change in settings pumps up Win7 networks

Why not just keep using Homegroups and change to 56 bit encryption? Although it's not as secure it works either way. As for these so called slow downs, I have not seem them myself and I've tested my wireless through two walls and 50 feet accross the yard and still get 15Mbps.

 

[karlsnooks]

You can. For a complete answer to your question, I defer to the aforementioned link.

 

[chev65]

Oh I read the link karl, the problem is that he disabled Homegroups instead of just switching to 56 bit encryption then he blamed Homegroups for the slowdown rather than just the encryption which is kind of lame considering that it's a well know that using any type of encryption tends to slow down file transfers.

Homegroups wasn't made to move files anyway, it was made to have a collection of all your pictures videos that reside on different drives all in the same place. Moving large files always works better using the standard Workgroup.

 

[karlsnooks]

Maybe a reread of the article, in detail, will bring you to another conclusion regarding his conclusions.

 

[chev65]

Sorry but I flatly to not agree with anything that guy said. Read what I said and you might eventually understand.

And I have some news for anyone who believes that one adjustment will make your WLAN go from very slow to very fast...It ain't gunna work.

Worked for me....went from 200kB/s to 2.3MB/s over wifi by disabling homegroups and lowering encryption.

sweet.
