How to speed up wifi rate?

Hi,
I have an i9100 with Broadcom dualband 1450 wifi miniPCI card.
This card supports 54 Mbit/s.
Wifi router is a Netgear WGT624 (108 Mbit/s).


Still, my max transfer rate is about 2500 kbytes/s.

Any clue?

Confirm you are running the latest Broadcom TrueMobile driver...

Also, you may want to consider upgrading your WLAN to the latest Broadcom chipset avail in the Dell TrueMobile 1370 or 1470 WLAN's.

FWIW: Broadcom has taken a very anti-channelbonding(108Mbps) stance since it creates way too much WiFi interference...(Warning: very corny audio track in the above linked video! )

netgear and everyone else uses proprietary software to increase the speeds. so unless you have a netgear wifi adapter, you aren't going to get the purported 108mbs

Laffingbilly, i'm not trying to get 108mbs with a 54mbd adapter :P

somms, i indeed had old drivers (DELL ones). But after updating with yours, nothing's changed.

Any other idea? Maybe some tweaking in the adapter parameters?

test it with encryption, etc off. I have the same adapter but only have a 11Mbit network.

Try what Mich suggested. If your bandwidth rate doesn't change, your Windows RWIN setting might require tweaking...

I've used the above linked registry utility in order to increase my RWIN setting from the Windows default up to the maximum (65535).

Before adjusting the RWIN, I could only get @3Mbps download speed using the Speakeasy speedtest site. After adjusting up to the max 65535 and rebooting, I now get the full 8Mbps advertised by Comcast!

do you have updated netgear firmware?

which mode do you have it setup on? b and g, g, turbo g, or auto 108?

do you have it setup where you have your wireless card MAC address in your access list?

are you assigning DHCP or designated ip address?

do you have your router setup high somwhere?

is your router near other wireless devices (i.e. telephone)?

have you played around with the channel?

on your wireless device:
power level, channel.
do you have a firewall?

it sounds like more of an interference issue due to router placement or power settings on your lappie.

I'll try unencrypted session to see changes.
I'll try to set the RWIN at 65535 (btw, how can i know what the current value is?)
I'll give my router setup later.

I had kept my router updated, but stopped because one said the earlier firmware was shitty. I may try the latest one now.

Keep posted

What happens if you have the router like 3 feet away from your workspace. And are exposure to radio frequency radiation can it be harmful. Or it dose not harm you.

thanks

2500 KB/s = 19Mbps (Megabits)

Not bad for a 802.11g network already but could be slightly better.

How fast are you expecting?

Well you are bombarded with radio frequences constantly. You're still alive.

Well, i am expecting something closer to 54Mbps!!!
Shouldn't I?

I might buy an Atheros if i'm sure i'll get a good speed with the WGT624

Well... no. Data transfer maxes out at 30Mbps at best for a 802.11g network, just like 802.11b maxes out at 6Mbps, and we are talking about ideal conditions. This is due to network overhead and parameters and other factors such as signal quality/noise/strength, distance and radio interference.

Check the routers config for Wireless... make sure that's it's enabled for Mixed Mode, and not just B or G mode.

I'll check my router config, and will do some test w/o encryption and will keep you posted.

My wifi laptop is on the same desk than the router, signal strength is excellent according to windows.
But if indeed max is 30Mbps, i might upgrade with a new wifi super G card compatible with my router.
