|Hi ??? - your last post suggests you have cured the fault.|
Because of the complexity of modern systems, on occasions it is wise to power off completely, then after a few seconds (not immediately) power on. This perfoms a cold boot, loading its operating system 'fresh'. Often forgotten is one's mobile phone which can benefit from this procedure - mine does.
Freebie internet protection programs are never as good as those purchased.
e.g. I use Norton Internet Security 2006 which supports my w2000 os, whereas nis 2007 does not.
There seems to be two majors in this field, Norton and Mcavee. Shopping around (ebay) one can find last years or earlier at knock down prices. Must be unused though. They offer a years protection including virus updates etc. Thus every year I purchase another new one (from ebay).
Statistics can help with such problems.
Google is your friend, e.g. try:- 'w7 wifi statistics'
An example of statistics usage:-
My desktop pc is old and about 2 feet from the router. The wifi was an add-on using a bluetooth usb dongle. The program that came with the dongle provided statistics which showed 100% connection strength, yet a huge (and I mean HUGE!) failure rate on downloaded packets. These were having to repeat in order to be successfully received.
Was advised being too close was the probable cause. It made sense anyway to use a direct connnection as this port was twice as fast as the wifi one, plus not running wifi reduced the load on my pc.
At times there are two other laptops (plus sometimes a ps3) all connected by wifi to my router. One laptop is watching Italian tv almost constantly. Speed is very good (my isp is TalkTalk) on my upto 8mb connection. TT hope to be upgrading to upto 24mb, giving 17mb usable in the near future.
Using speedtest is interesting, because it recommends the best server for the test, AT THAT TIME.
However this can be over-ridden. Thus sometimes I compare my 'near London' results, to one in Naples Italy (where my wife is from), and then Sydney. The distances involved make quite a difference.
