i have 1mg broadband with ntl

i have connected a netgear router

my son uses a Dynamode High Speed 54Mbps Wireless USB Adapter on his laptop

however it keeps disconnecting, quite frequently, its very frustrating for him, anyone know why?

thanks guys :thumbsup:

But it does connect??..have you tried changing the channel number on the router ..if my memory serves me it comes as default on ch 11...I had this problem and changed it to channel 7 ...and sorted...give it a try.
#2
yeah it connects, then the signal goes from strong to weak then disconnects, i'll give that a go thank currychops :)

Just another thing to check for things like this.

Go to Device Manager (sure you know where this is by now :) ). Choose the USB Wireless Device (most likely under Network Adaptors), Right Click and choose 'Properties', now I can't remember from the top of my head, but look under all the Tabs along the top and in one of those you should see an option for allowing Windows to power the USB Device down - Untick this option.

Also, on the router, as daft as this may sound but make sure the aerial points towards the general direction of the receiving PC and is not in a place where people often walk by, as on some routers (not all) the possibility of people actually blocking the signal is there. Depends on the sensitivity of the receiver.

any household appliance that works in the 2.4ghz band eg microwave and cordless phones etc may have an impact on your setup, but normally as said above a changing to another channel will normally sort it out.

ok guys... i have follwed all advice, the signal said excellent... but disconnected within 5 minutes :-(

The other thing to take into consideration is the time of day. I am supposed to have 4meg but find from 18:00 until 22:00 my signal can drop to 1 mg and this is on cable.

tonyd - Problem with that is, you keep your connection. Wireless signal strength is down to the individuals equipment rather than any peak time connection issue.

lou - If you've changed the channel and done all of the above, the easiest thing to do is have the router next to the PC and see if the connection still drops. This will show that both items are working as nothing will be able to interfere at that range, including neighbours routers or wireless video senders etc

fox2020 - Sorry, but no portable phones/microwaves etc work on the 2.4ghz bandwith, this frequency is reserved for devices that require send/receive capabilities such as Wireless CCTV, Internet, Video Senders, Baby Monitors (sometimes).

If you still have trouble with the item at very close range, then I'm afraid it could be a problem with either item. First point of call is to see if the Router firmware can be updated (Manufacturers website). Another thing to look at is how many USB items are plugged in at the same time, as some boards share the 500mA allocated between more than one port at a time, so anything else could be pulling the power down. If there is any other USB device plugged in, unplug it and try again.

Anything else crops up, let me know.

I take it you are connecting to your own router and not someone else's? that could cause it to drop, check the properties on the laptop.

So is it now sorted loupomm?
#11
no :(

its very random but get to have a solid time span without it happening, ive tried all suggestions, im thinking now maybe there is afault there somewhere, must be with the router as we have tried 2 seperate dongles, but the pc we have upstairs has a dongle and it never looses connection, my knowldge of all this is very limited so its very frustrated!!

thanks so much for all help received :):)
#12
Well all you can do...I think it has been suggested..is ensure you have the latest firmware installed...I'm not sure about dongles ..do they have drivers/firmware? ..if so try and install the latest versions.

What Netgear router have you..the model number and version number... as I can then give you a link for the updates for that if you wish.
#13
You'll have to find the Dynamode site and see if there are updated drivers.

Then show me any portable phone or microwave that works within this frequency range...

1. Domestic Microwave Ovens

Domestic Microwave ovens employ cavity magnetrons, which generate RF radiation at a nominal frequency of 2450 MHz and a CW power level of typically 600 – 1200 watts. In operation, the magnetrons are operated either continuously for the duration of the cooking cycle, or pulsed on and off over a period of several seconds in the case of lower power operation (e.g. for defrosting frozen food).

Investigations carried out by the RA7 show a variation in the frequency and level of emissions from microwave ovens, depending upon factors such as the age of the unit and the heating load, but in general a 30 dB bandwidth of c. 200 MHz, nominally centred on 2.44 GHz, was observed.

Down and install netstumbler:

It'll provide a nice picture of what wlans are near you and what could be interefering, as was mentioned before most default to channel 11 so choosing another channel will help stop any intereference if there is another router nearby also on channel11.

Ok then, in that case I accept that it is possible for a Microwave to run with a 2.4ghz frequency carried off.

But, this is just what researchers have found on some microwave ovens - there are too many different factors that could contribute to it giving off this frequency and I'm not convinced the area covered would interfere with anything else.

Any way you could find out from what distance this frequency covered from the microwave ovens?

how do i change the channel?

I had this problem and was told to change the channel to 1, so best checking out with your provider to see which channel to change it to

I had to go through an internet page (not connected to the internet) could tell you the addy, but wouldnt work because it was an orange site. You would have to ask someone who either has ntl and has done this in the past, or call ntl

Of course there could be an easier way, but if there is then I dont know of one

Will try to find out:thumbsup:

Still not too sure about the distance:-(

"older microwaves have poor suppression and will interfere... i know this for a fact as I have a 2.4ghz TV sender. When the microwave is on there is just static when the microwave is off the picture is fine."

"More than likely its a c. 700W microwave, and about 99% is shielded. Given most wifi routers are in the 20-30mW range, thats still pretty overpowering."

Thanks to jay_oasis and herulach for the above info:thumbsup:

Hi, loupomm any luck yet?

The only thing I can think of with regards to distance is along the lines of equipment used to test whether a Microwave is emitting radiation, which would usually be used within 50-100mm.

Anyone have a frequency counter handy?
#25
Loupomm the router should have that option under its wireless settings

What is the model of your Dynamode router?

I ask because an antenna off ebay would probably improve things significantely

i have no idea the info you need, so this is the spec of the ebay page :)
