Slow speeds within LAN

[Matt2]

Hi everyone,

I have 3 computers connected wirelessly via a D-Link DI-614+ wireless router and D-Link DWL-120+ USB adapters.

THe D-Link software says that I am connected at 11mbps on all computers and signal strength on all computers is 80% or above.

When I file swap between the different computers, the fastest transfer rate I get is 2700 kbps (2.7mbps)

Why am I not getting anywhere near 11mbps? I understand that I will never get 11mbps but it would be nice to be able to get more since I usually move very large files (600mb+) between computers.

Thanks!

I can't say for sure wether or not that is an expected speed range as I have yet to actually test out my own wireless speeds, but if you have WEP enabled, that is commonly known to slow things down a good bit.

My experience with the same DI-614+ with WEP enabled yields similar results, that's as good as it gets I expect.

11Mb/sec. is the "Speed" of the Internal Wireless Hardware.

In reality the yield is 4-6Mb/sec. This means that you have slow Wireless, but not so slow as you think.

The computer Indication of Signal Strength is to make the crowd happy (or sad) but it not a Real measure of actual signal propagation.

You might have Electrical noise in the background.

Consumers 802.11b were not conceived with the idea of moving huge amount of files.

Wire your system or try 802.11g.

probably disabling wep will speed you up 2x or 3x

No, it probably won't. Newer routers lose 10% (tops) of their speed with WEP -- they do the calculations in hardware. Realistic data throughput for an 802.11b *NETWORK* is 4-6Mbps. You can push it to 8-10 with good chipsets and excellent signal conditions, but that's unlikely to happen in your house. Some of it is used as CRC bits for the data, and the rest is lost to crosstalk, collisions, and interference.

However, note that this is the throughput for the *network*. Only one system can be transmitting at a time -- otherwise they collide. It sounds like you want to relay files from one wireless system to another, in which case you actually use double the normal bandwidth (1x going from system A to router, another 1x going from router to system B). That's why you get like 2-3Mbps. Try plugging one of the laptops in and see if your transfer rate doesn't double.

Okay. I've got the same router....I've got 256 bitWEP enabled and I'm def eaching higher speeds than that.
First off, make sure you've got 4x enabled on the router and the client side. You may want to screw with putting on encryption off then try 64/128 and finally 256 (if you've got the dlink PCI card this will work)
I would also switch your channel to 11, not the default (think that is 6? dont quote me on that) anyway, jsut generally speaking its better to use 11 cause the other is more populated (generally)

I wouldn't upgrade to G, you really won't see that much difference....If you truly want to transfer large files at high data rates you need to be wired. As someone stated earlier, b is intended for *net access...not supporting servers. though im sure you know this and it won't help at all..hehe...
Matt is right abuot transferring from one wireless to another wireless takin up double throughput...keep that in mind
Slight possibility if you have a cordless phone, some other device, it could be disrupting it..but doubtful.
