LAN connection for internet help please
Im not an expert on computers.
At work i have a desktop and laptop. desktop connects to internet via LAN cable and the connection speed displays as 100Mbps.
Laptop conects via wireless at 11Mbps. If i try and play videos (youtube etC) they forever stop and wait for the download to catch up.
In my fuzzy logic world i thought if i connect the LAN cable into the laptop i would get 100Mbps. Unfortunately i cant get the internet toload up when
i switch off the wireless.
In network connections i can see an icon that says the LAN cable is connected and this displays 100Mbps but i cant open any pages in internet
explorer.
Does anyone know what ive done wrong or if i need to change some settings so internet connects via the LAN?

withount knowing the settings at your work i cannot be 100% but you may need to use a proxy server to get out, check in internet exploerer proxy
settings, also, if you do not use dhcp you will need to set your laptop a static ip on the wired nic.

Hi Darren. It may be that your LAN connection is not configured in the same way as the wireless. I would guess that your wireless has DHCP enabled so
that it's given an address automatically. The LAN needs to be the same too.
Could you press Start - Run and then type in "cmd" (without quotes) Hit enter.
At the command prompt now type "ipconfig/all" Hit enter.
If you still have the LAN cable connected you should be able to see both connections listed and also what IP settings have been applied to each card.
We need to replicate that on the LAN.
My guess would be that the LAN connection needs to have DHCP and it's presently on static address.
Can you copy the ipconfig results and post here?

The proxy will be setup in IE, or whatever browser you use, so it wont be that, as it will be the same no matter what connection type you use.
my guess is that if you surf the net with your wireless, then connect the cable, then disconnect with the wireless you computer will still be looking
to connect over the wireless lan, and due to it being disconnected doesnt immediately know where to route the data.
i would try disabling your wireless, then restart your laptop with the cable plugged
in.
in the end though it wont make a difference ... if you are connected to the internet via the fastest ADSL you will be getting what.. about 6.5Mb/s as
8Mb/s is the max theoretical speed  your wireless will be at 11mb/s thus your internet speed is not being throttled by being connected to your
wireless 
it will be slower, and choppy due to the performance of your laptop

wireless may be on a different subnet or have different route rule

Do the videos play fine on the desktop?
I ask because 11Mbps is way faster than almost any home internet connection available in this country and most people don't have a problem
wathcing online videos with 1-2Mb connections. So it seems more likely that the bottleneck is in your company's connection to the internet
rather than your connection to the LAN.

just because the wireless says its connected at 11meg doesnt mean you will get 11Mb through it, you only really ever get 80% on available bandwidth
when using tcp/ip due to over head to straight away thats about 8 meg, now if its a 11Mb access point and 5 people are using it, divide 11 by 5, take
80% of that and you have your real available bandwidth, no where near the 11Mb you think you have

Doing some tests a couple of years ago on wireless connections we found 11 Mbps only gave a throughput of 2-3Mbps presumably due to the extra overhead
on wireless.
I agree that standard Ethernet will max out at around 80% though

Nothing to do with proxies Windows is routing internet address to the wire less adaptor.
You will have to set the wired ethernet lan connection up as the default connection, in the internet options applet of the windows control panel.
Then either reboot or shutdown your browser and stop the lan connection and restart it.
If you find this reverts to the previous setting after a reboot try creating a new restore point before you shut down.

Many thanks Mooky for taking me through the solution on the phone. As others have said it was the addresses that the LAN was set to. letting it get
them automatically cured it.
Many thanks,
Darren.
