Nvidia driver versions

[Zenflyer]

Hi steam community. I need advice concerning nvidia driver issues. Firstly what do I need to do to determine that my currently installed nvidia driver 7.15.11.8250 is 182.50 or 170.X series. I tried google it to no avail. Could vga drivers caused network lag? I could join a L4D server starting with as little as 19ms where it suddendly shhots up to 1600-2500ms making it totally unplayable. Strangely CS 1.6 remained a constant ping of 16ms thus could play through in such a network intensive fps shooter. It is no reason why L4D should lag so much. I am so confused. Could it be that the OS is corrupted or network driver(latest installed by default) or vga driver? Does a reformat helps? Also Internet Explorer 8 kept crashing like never ending.

Please advice.

Your driver version is the 182.50. You can tell because if you look closely you can see this 7.15.11.8250.

Is there anyway to fix L4D network lag? I tried openserverbrowser command at console to search for the lowest ping server. i.e.<20ms server it intially joins with 18ms then it slowly increases to 50ms>180ms>400ms>700>800>1000++ > lastly 2824ms within a <20seconds. I am using a linksys WUSB54G wireless adapter and could previously play smoothly even in those high ping servers 200+ ping. To date, even those local severs <20ms ping are lagging worst than previously those 200+ ping servers. The strangest thing is, CS1.6 didn't even lag at all and it remained a constant 20ms whenever gaming throughout and I could get frags of 6win 2 lose at a 10man per side match. I have reinstalled L4D but to no avail. Graphics driver from ancient ones to latest ones roll back to current one which L4D community recommends. Linksys driver is also the latest and there is only one by the way. Can anyone make out what could be causing this lag here. Really pissed off. Joinging a local campaign server with noobs around of similar ping but only my ping rises where theirs are in the green zone.

One question: Could it possible to be software related issues casuing network lag ONLY in L4D? Currently running widows firewall apparently turning off doesn't retuen the bandwidth. I couldn't get a chance to hands on ethernet due to the router being situated far away. Previosuly being able to play this game without lag on the linksys wireless adapter doesn't seem to show anything about the physical connections. Please advice.

My negligence sir. Wonder why nvidia listed these series of numbers under device manager tabs.

Have you checked for sources of electromagnetic interference (http://en.wikipedia.org/wiki/Electromagnetic_interference_at_2.4_GHz)? You can use this (http://metageek.net/products/inssider) to identify nearby networks using the same wireless channel.
