Why is lappy wireless connection slow?

[Hayabusa Rider]

I have a Dell 8500 with a dual band wireless internal card

I downloaded a file on the desktop at 650 kb/s which is more than 3 times as fast as I ever had on the lappy, and DSL reports says the connection speed is 3.4 mbps on the desktop and 1.3 to 1.5 on the lappy.

The router is an 802.11b and nothing encrypted

What gives, and what can I do about it?

May be this can Help.

Download DrTCP: <a target=new class=ftalternatingbarlinklarge href="http://www.dslre

Run the program, it will show the current settings of TCP/IP parameters. Write them down.

You can change any variable that you want, click Apply, and reboot the computer, if no good; you can always change to your original values.

Start with:

MaxMTU - for DSL =1492 Cable=1500 DialUp=576

Tcp Receive - 255552

Window Scaling - Yes

Time Stamping - No

Selective Acks - Yes

Path MTU Discovery - Yes.

Black Hole - NO

Max Duplicate - 2

TTL - 64

Notice it said above Start with

These settings are not written in "stone" there is variability depending on the computer other setting. So try few setting and measure your Download for each setting.

In addition, in case a person has a Router the Router's MTU if set differently can affect the general MTU.

Thanks for the reply Jack. I tried various settings and got no where fast. I then unplugged all 2.4 mhz equipment in case there was some weird scrambling of signal (wasnt too hopeful on that one). I then went and replaced the router with an 802.11g unit (this is a dual band lappy and can take advantage of that, at least in theory).

All the same.

I dumped in in Dell Support's lap. Hopefully, the can at least provide a reason this is happening.
