Hi Maiku and thanks for your reply concerning my PCI Wireless Card.
The model I purchased, back in around 2010 is an Edimax-EW-7128g-pci-wireless-card which used to have an extended longish cable fixed to a stand (see pic).
But this wire snapped away from its housing, so I just screwed on a normal stick antenna to the back of the card (see pic).
Also, strangely enough, over time, and a couple of upgrades to my operating system, the original Edimax Driver which I installed from the CD in the box, now shows the device as a Ralink RT61 Turbo Wireless LAN Card in Device Manager, not Edimax.
I have included in this post a System Summary using the in-built Windows tool, plus two other system scans, one using CPUID, and the other with Belarc Advisor.
My ISP is iinet and I've just upgraded my ADSL to NBN, which is as you would know, much faster with downloads and browsing, etc. The provided the modem and I also use my landline phone plugged into it. But even with the fast NBN, I still get blockages and cut-offs at times, and also speeds drop considerably now and then. So I thought this problem was caused by my wireless card not functioning properly, or maybe I need to change the options in properties, device manager. I've updated all my drivers and had a go at moving my PC closer to the modem, but this did not help very much.
Anyway, I hope I haven't gone overboard by including so many attachments and pics, but you did ask me to provide detailed info about my system.
Hey, please don't go to a lot of trouble with this Maiku. I appreciate you even bothering to reply, since my original post was under the Graphics Card section and I really don't want to waste your time helping someone you don't know. OK then. I'll leave it up to you, but there's definitely no hurry, OK? Cheers. Glennie
