Wireless F's the network!

Umm yeah as the topic says. I have an internet running off an ADSL 1 connection, running a Netgear D6200. I both do gaming as well as downloading. It doesnt happen all the time, but seems something the wireless users do on the net which make it download at a max of 50kb's, and when I game I usually get an ms of 40, but when the wireless users f it up, it goes from 150-50000ms with drop outs etc..

Disconnecting the wireless from the router "fixes" the problem. I dont stand over watching the users, but I think they know what is causing the problem, but wont say. Its not like a download or upload, once the problem starts it happens for hours. I had the problem about a year ago, and it seemed to be one site one user was using that caused the problem, I forget how and why.

I have also had a couple more problems with the setup including, an older router no longer being able to connect to the ISP, but upgrading to a newer one fixed that. A fortnight later im pretty sure they are making us share line and the download speeds have halved. And thirdly is the main problem of the wireless users making the connection unusable on an Ethernet connection.

Each problem has started at different timelines so seem independent of each other. How can I go about finding the problem and making the internet usable for all?? (Main problem being wireless connected = high ms in games and very low download, other things mentioned cause they may be part of the problem..)

Thanks Gandog!

do multiple speed test over a span of a day and see how that compares to what your plan says it will deliver.

I have done, in regards to the speed tests. I use to get speeds of 800kbs-1mb a sec, which as much as you can get with ADSL 1, but that has dropped to 450kbs. As well as that when laptops of phones are connected to the wifi it is stuck about 50kbs if that (F'ed).. Even when a family member leaves her laptop on standby, it is still connected to the network and cripples the speed.. (This has happened with two different routers.) (Also they can connect and the connection can be fine sometimes, but most the time it cripples the network, other times it doesnt???)

So as I said two or three different problems which is highly frustrating and im not sure how to identify the problem. In regards to the speed halving I have talked to the ISP and they say its still within the reasonable speed for ADSL 1 so wont do anything further about it. And the box down the street we connect cant to take ADSL 2 connections...
