I have this wireless router, but it doens't seem to be pumping out the full wireless signal. EG On a download from a computer wired to the router i can get 234kb/s download speed. But on a laptop in my bedroom one floor below, the download speed is only 48kb/s. Its exactly the same file, from exactly the same site.


Any tips on how I can get the same speed to the laptop. I have tried sitting the laptop next to the router but the speed still doesn't go up.


Many thanks

Rob

Wireless isnt as fast as wired.

Wired will be 10/100/1000 mbit.

Wireless will be max 108mbit but prob 54 or lower depending on the wireless kit in use.

Sounds like yours is 54mbit.

On top of that you have protocol overheads, encryption(you have some?) etc that reduce the theoretical max to a real world max, say 48mbit.

then as the signal strength declines so does the bitrate, so downstaits (through the floor/ceiling) its hit the signal strength/bitrate and reduced it.

Download a copy of Netstumbler and check to see what other wifi access points there are nearby and what channels they are using.
Overlapping channels will cause signal degredation...

As said, Wifi is currently no where near as fast wired. Also the radiation pattern from a typical Wifi antenna is roughly donut shaped, if you are directly below the router you will not be getting a good signal strentgh and so your throughput will drop.

What throughput can you get with the router directly next to the laptop? If your throughput drops markedly anywhere in the same room as the router then you need to look into causes of intereference.

Once you start introducing walls and floors into the signal path then you need to start investing in better antennas.

Okay, another question.

The router I have is a D-Link DSL G604T. Today it just won't let me connect to the internet. Even on the computer that it is wired to nothing comes up. Theres nothing wrong with the connection as I tried another modem and it worked fine.

This is on BT Broadband. I've just spent the last hour trying to figure out whats up with it but I can't figure it out. Would it help to try just unplugging it and starting again?



How good is the router? Or is a router just a router? Have a feeling I might just swap it for another one.


Thanks

Okay, another day but still having the same problem. The router is randomly dropping the connection, but it still says that its connected, and I don't know entirely how to get it back on, I've been randomly trying things just to get it back on. Does anyone have any idea why the connection is being disconnected? My laptop has good strength to the router, and I can connect to the network, its just the internet that keeps stopping. Even stops on the wired computer.

I have attached a page of the connection settings, so maybe someone can help from looking at them?



My latest effort is to change the 'keep alive' setting to max, as before it was set to 10 minutes, would this be the reason it was disconnecting?

username should be polar.bert@btbroadband.com or whatever it is).
Leave the Password alone - it should have 4 asterix by default. It yours doesn't then you need to delete the connection and set up a new one.

The username is there i just edited it out for privacy sake.


I read on the net that it should be 'bt' is this not right?


Also what does keep live mean? Can I put a number into that box that will 'keep it live' all the time? I assumed that it meant how long the connection to the internet was kept active, is this right?

Not sure. Mine is @btbroadband.com
I have the same router. In the last 6 months I think I've had to reboot it no more than once.
My old one had a problem which DLink resolved very quickly y sending out a new one.

It looks like your problem is that you cannot get an internet connection to the router and is probably to do with the settings of the connection.
Try to delete the connection and start again.
