Hello!
I have T60, vista business, Intel(R) PRO/Wireless 3945ABG network card, ...
The problem is with WiFi no metter where I am locating. In service organization one of experts said, that there is no network with so high speed my notebook support.
So I bought Wireless N router (yes I know that this is just a marketing), but this router support till 600MB in local network(as said in utillity) and 100Mb per one host.
But there is still no differece with my 60% signal strength. Even if I'm standing next to router.
Could anyone suggest me anything usefull?
Thank you.

The 2 things you need to do at first is to:
1. Run the Signal Diagnostic on the Intel Adapter
2. Check your transmit power setting, which is the most likely culprit. Your other settings could be set incorrectly as well for use with an N router, but I'll tell you what to check there as well.
Diagnostic
1. Open up your Network and Sharing Center, then click on Intel PROSet/Wireless Tools in the lower left column.
2. Run the test by clicking on the Diagnose button. You can run them all or uncheck all but the Signal test. Click on the "Run Tests" button when you're ready to proceed. Any problems will display in the Signal's Test Summary field.
Radio Transmission Power and other Wireless Adapter Settings
1.Open up you Network and Sharing Center, then click on Manage Wireless Networks in the left column.
2.Click on Adapter Properties, and then click on Configure.
3.Click on the Advanced Tab.
4.Check your Transmit Power first - Set it to 5 (Highest). If it's already at 5 then your problem is elsewhere.
5. Go through the other settings:
(I'm going through my Intel Adapter settings, which should be pretty close, even though I've got an AGN adapter)
Wireless Mode: 802.11a/b/g (with N routers you need to have A in the mode mix - it's a 5ghz frequency. Using only B/G will let you only use one frequency band of the N combined signal.
Throughput Enhancement: Enabled
Roaming Aggresiveness: 5 (Highest)
Mixed Mode: CTS to Self
Fat Channel: Disabled
Channel Width: Auto
Mode: Enabled
Ad-Hoc Power: Disabled
Ad-Hoc QoS: WMM Enabled (you need to set your Router's WMM to Enabled in the QoS setup section as well to use this)
That sets your adapter. Check your signal strength when you get done.
Router Settings
Although this setup if for a Linksys WRT600N Dual-Band Router, the settings apply to most N Routers even though the exact setting terms might be a bit different. Where the settings need to be changed because your hardware is different (your adapter isn't N, whereas all of my hardware is DB-N) I've adjusted the settings accordingly.
1. Router Network Mode Setting - Mixed. Your adapter is a mixed wireless standard unit (A = 5ghz and B/G = 2.4ghz) and even though the N standard uses both frequencies for wireless transmission, the different standards cause problems if the router is set to broadcast just one standard.
2. Radio Band: Mine is set to Standard, 20mhz. Try both auto and 20mhz to see which is better. Remember to set your adapter's Channel width to the same setting whichever you decide on.
3. Network Name(SSID): ALWAYS input a unique SSID for your network. Believe it or not, one of the biggest problems people have with N routers because of their extended broadcast range, and the fact that most people don't change the SSID to a unique ID (leaving the default) some people actually will mistake a neighbor's network broadcast for their own. What, you think you're the only one in your neighborhood with an N router? If you don't ID your network with a name that you can positively say is yours, and if you just leave the default, and your neighbor does the same thing, when you go to connect, you stand the chance of connecting to the wrong network. Big tipoffs will be that your Security key will never work no matter what (wonder why??) and..... your signal will be much lower than it should be.
4. Wide Channel: S/B set to Auto.
5. Standard Channel: Set it to a frequency that's offset from the base frequency of 2.4ghz. Try using channel 11 (2.462ghz). Many of the items where you live and work use 2.4ghz and 5ghz for operational frequencies, and can interfere with your network
6. SSID Broadcast: Enabled - Not much good to use a unique SSID if you're not going to broadcast it so you know which wireless network is yours when your adapter scans for wireless signals.
You should have a QoS (Quality of Service) setting on your Wireless setup under Applications and Gaming. Open it and you should see settings for Internet Access Priority (Enable it) and MAC Address under Category. Enter your Adapter's MAC Address, and set the Priority to Medium. You can get your Adapter's MAC Address by going to your Accessories folder under Programs, then clicking on System Information, Components, Network, and then Adapter. Scroll down until you see the Intel Adapter listed - there will be several others listed as well besides that one. The MAC Address is toward the bottom of the adapter summary.
Setting your router and adapter up this way gives your adapter priority access to your 'net connection over other devices and traffic.
Security - I don't use any of the Encrypted Security settings (WPA, WEP), since N devices have been found to have a "minor problem" dropping a connection from servers during online gaming, and I game a lot online. You can achieve the same result by using MAC Address filtering, which will only allow MAC addresses from devices you want to access your network to have access to your network. Any other device not on the list requesting access won't even be acknowledged. Great also for pesky kids trying to steal bandwidth for their **** downloads - it keeps them out so you can perform your OWN **** downloads at better speeds.
REALITY CHECK
If you really want to get the most out of an N router, then you need an N adapter as well, either a USB, PCMCIA, or if portability and power isn't an issue, you're best option is a gaming/media adapter. Gaming/Media adapters plug directly into your Ethernet port, and you set it up with your Router as if it were a wired connection. The Ethernet connection gives you much faster throughput than a USB or PCMCIA adapter.
This should give you some help in narrowing down or fixing your problem. -
The intel 3495G is only wireless g you won,nt get the wireless n speeds
you laptop might have n attena in or be n ready
wireless g = 54 meg
wireless super g = 108
wireless n = 300
but need both n enable wireless card your laptop and n enable router
you also need be run wpa2 aes or tkip i can,nt rember sure some one else post tell right one
Intel(R) PRO/Wireless 3945ABG \
is wireless a b and g
your laptop card does.nt do n
T60 wireless shows only 60% signal quality
