Wireless Dropouts

Well we got a wireless network set up at home a couple of months ago to go with the new ADSL connection. I got a TP-Link Wireless card in my computer and most of the time it was just peachy.

But now there are constant dropouts (the wireless client reports 0%-8% signal strength, not enough to even connect to the net). It is really, really frustrating >:(

I'm using a Netcomm NB5Plus4W modem/router.

Any help appreciated :)

have you checked to see if neighbouring networks are interfering? you may need to change your wireless channels.

Screw your antennae in properly.

I think the TP-Link cards available in Australia have fixed antennas.

maybe the the one on the Netcomm router is loose.

There is one other network...but my computer can't pick that up, only my sisters laptop can. How do I change wireless channels?

Btw, both of the antennas were screwed in properly.

Also check the antennae on all devices are screwed on firmly.

edit: that's what I get for opening a page and responding to the post three hours later.

First thing I'd do is stop faffing about and actually isolate the end that's dodgy. :)

Are all wireless clients getting shitty signal? If yes, then it's the router. If it's just your PC, then it's the wireless card.

If all the antennae are screwed in firmly and pointing the right direction (if it's adjustable, in which case straight up is how it should be, to the best of my knowledge) then it's possible that either the card or the wireless AP are just rooted.

You could try the card in antoher PC and if it's the same deal, then time to buy a new one/RMA.

in the mean time drop your MTU size to about half of whatever its set to now.

You dhoulfnt notice any difference unless your trying to game on wireless. at least halving it should give you stable internet use

I have a cordless phone, but it operates at 5.8Ghz, not the 2.4 of the network.

How do I change the MTU size, I can't find the option anywhere (checked router and wireless card settings).

I'm a bit skeptical of the whole MTU size changing. It sounds like a really bad idea to me.

Have you tried changing the channel of the wireless AP? If there's little interference, then channel 6 is usually a pretty good choice. I believe it's the most common default.

And it'd be good if you'd give some indication of the things you're trying and what kind of results you're getting.

Why?

in very basic terms. MTU = maximum transmition unit.

aka. how much data the wireless network is sending per burst.

the up side of lowering it, is that if it loses a packet, it has less to re-send.

As a wireless network is well above our max internet speeds (24mbps for ADSL2, 54mbps for wireless) 'slowing' your network means nothing unless you're pc to pc file copying.

as i said, all it does is mean if hes losing packets, and thusly dropping a connection, this should help by not losing 'whole' packets. just partial ones.

The option should be on the roter somewhere, usually in wireless advanced setings.

and on the PC, go into device manager, and it should be in your card properties

Fiddling with the MTU is a bad idea in this instance because it's just likely to cause more problems. The OP has stated (s)he is seeing reduced signal strength on the wireless client and this is obviously nothing to do with MTU - why bugger around with settings unecessarily?
