Windows 7: Win 7 Net Speed, possible tweaks

Note: Like most folks my level of knowledge is not high, but I know how to get out of things before I get into them. If like me you are low on experience set yourself a Restore Point before embarking on changes. Take notes so you can backtrack your way out.

After a few 'improvements' transmitted by Microsoft's Update Service, my internet speed dropped to 16% of its former self. Like a lot of others I searched the net for some advice as to what might have changed or how I could get my speed back. Some ideas where good, others a waste of time that did nothing but add confusion.



It seems Intel(R) 82579V Gigabit Network Connection is a common feature, and somewhere in one of the updates has corrupted settings, well thats my theory. I used the intel utility to ensure I had the most recent version driver

Over a few days I observed the problem, I noticed that my speed fluctuated, I began to think about settings more seriously and had a play with what seemed logical. BTW I use DU Meter which is an excellent way to check speeds. I think I had a breakthrough last night and thought it might just help someone out with this seemingly common issue

The part with NetBIOS was the source of my personal breakthrough,
the rest were just settings picked up along the way, or trial and error
