Setting up wifi security

[newsh]

Hi guys

I've been trying to set up a password on my router but when I do I get a "this network has little or no connectivity" message, I've tried wep and wap and whatever, no go.
So I guess I'm connecting to the lan ok but not passing through to the internet. What am I doing wrong? my router is quite old, a 3com 11g thing and I've read the on board help.
I've never bothered before but now I have a neigbour with a pc.

TIA!

check if the client pc has the right IP addresses. the dns and gateway should be the ip of the router, the ip of the client similar as the router's just different last numbers, example router: 192.168.1.1, pc client 192.168.1.5. hope this helps.

not much help but could try

rename the WiFi network to "Police Surveillance Van #02".

That should keep the neighbours on their toes for a while.

You could try some updates , firmware update for the model of 3com you have, and drivers update for the wifi card on your pc.

router has two sides, IPS side (automatic) and LAN side.
You cant, dont want to mess with the IPS side (unless you now what u r doing). On the LAN you can config few things:
Local DHCP Server: on/off (Enable DHCPserver if you want the router to automatically set the IP address to eachcomputer. Select Disable to manually assign IP address to each computerconnected to the router.)

Start IP Address (Enter the IP address you want to start assigning IP address to eachcomputer connected to the router.) 192.168.1.x

Number of Address Enter the numberof computers to assign IP address. Enter the number of computers you havein your network. This will let the router know how many computers are onyour network. It is recommended to minimize the number of IP addressassigned for security reasons.

DHCP Address Range This will display the range of IP addressassigned in your network.

Those are the basic things. Go with dhcp, so your pc will get every info without manually adding.


if its in a home, where not much new laptop will try to connect to the net via this router (like an office), just simply deny acces to the router unlest pc' mac address added to the list on the router.

it will show up an unsecure network, but noone can connect it unless you manualy via wired pc added them to the list.

Its not bullet proof but "they" will need a "little" time to try every mac address combination

thats what i do.....and let them try to connect.....and let them try to connect.....and let them try to connect.....and let them try to connect

but if you want to be on the safe side, add WEP or WPA2

from the client can you ping the router - in fact can you IPCONFIG /ALL to determine your own address, and if you get a reply from the router perhaps try pinging something like www.3com.com to see if you can view the world - - -if none of this is working try pinging 127.0.0.1 to determine whether issues are with network card.

There are some variants of WEP and WPA that can catch you out as everything isnt always interoperable with everything else - and some schemes force a pwd of certain length - which it may not be telling you about.

WEP isnt particularly strong but its better than nothing.

Another handy way to constrain which machines can access your WiFi is to hard code the MAC addresses - this means you don't need WEP or WPA to access it - and the other trick is to have your router not publicise its presence... i.e only you know its name

when you create your password - using a null character will completely **** with anyone trying to sniff your network SSID :mischeif:

[newsh]

I typed ipconfig into the run command and an empty dos windo opened, I typed all into it and it said something but closed immediately. not it just opens and closes before I can read what it says

I'm pretty rubbish at this stuff, I only understand about 30% of what you guys have written..

How do I ping?

I typed ipconfig into the run command

type "cmd" without quotes in RUN window, hit enter and type "ipconfig /all" in your command prompt.
Then it will not close.

So I guess I'm connecting to the lan ok but not passing through to the internet.

You could access router's web interface and check if your router has got valid IP address in WAN section.
Example from mine router. I'm also using MAC filtering (whitelist) with no other security.
