Wireless Networks

[dave_m]

Just a bit of advice to anyone using a wireless router.

 

if i wanted to i could have free internet access as several of my neighbours have unsecured wireless networks, many of them have not even changed the admin passwords on the router :blink: which means anyone can access the settings of the router using the default IP address and password which on most routers are the same - and possibly worse access personal data on their computers

 

so a note to anyone using wireless, make sure you secure it!!! :huh:

[morticiaskeeper]

I warned my neighbour that I could use his network, but he's never secured it, very useful when my connection went down :blink:

 

My network appears to be unsecured, until you try to login. Only a select list of MAC addresses are allowed in.

[Bigjeeze]

Add that to the low speeds on wireless and the no doubt soon to be discovered dangers of radio in confined spaces and I am happy to be on my hard wired network.

 

I work from home and my laptop is always picking up other networs and as you say they are unsecured - its basic stuff but the fact is most people havent a clue.

Only a select list of MAC addresses are allowed in

.

 

as is mine with WEP, most secure at the moment seems to be Mac filtering + WAP, even Mac filtering can be broken by mac spoofing - although I couldn't tell you how :D

[Masked Marauder]

I could. And it does not take many packets to sniff the MAC and the WEP Key.

 

Thank heaven for all the open networks, Skype on a pocket PC saves a fortune compared to mobile calls......

I have a linksys system and my Dell M70 has wireless and no one could hack into my laptop. Mainly because I can't get the bloody thing to work.The laptop see's the router but asks for some sort of ID I typed in some password my mate told me to, it the say it is connected and all it dose then is puts a message up saying trying to get ip address.

I tried loads of things to get it to work but it's all packed away in the box :D .

The pass key has to be entered into the router and converted to 13 hexidecimal pairs, this is then the passkey you need to put into the box asking for the passkey on your lappy.

 

So say your passkey word was fordgalaxy, that converts to D3 13 D9 CC 20 3A 09 8D C4 67 5B 10 1B and that (without spaces) is what you need to put into the PC.

 

This is the most common mistake made by home users who try to set their wireless kit up. They then give up and don't use WEP encryption.

message up saying trying to get ip address

 

the linksys router will need to be set up as a dchp server or you will need to put in the ip address manually - in the correct range :D

i have 3 pc's on my network 2 are wired with ethernet cabling the laptop is on wireless, if i am not using the wireless AP then its turned off. The wireless AP i use is quite good as it has an event log which lets me know if anyone has been trying to access it and it shows me their MAC address which can then be blocked from further access attempts!

[NikpV]

why don't you just set it to block all mac address except but your laptop, if you get somebody turn up with a laptop and you want to allow access, let it try and move the mac address from the event log and allow it access

Ok I tried to set up the network again tonight i have all the bits needed , my dell has wireless I have a laptop card for my toshiba and a usb wireless for my daughter PC upstairs.

I have all the manuels as they are all new bits.

 

On installing the router it asks for a password in the book it say's use admin it won't go any further and that is about as far as I got :wacko:

 

For a total idiot (not that I am :huh: ) can anyone give me a step by step tutorial please, just for the dell to start with I don't want to confuse myself to much.

 

Thanks

does it say that its the wrong password or does it just hang, have you tried setting it up before - exactly what linksys router is it ?

[Justice]

Hi it is a Linksys wireless-g 2.4 ghz

I enter the admin password and the box disapears so I push next and it goes through the checking the system dialog and comes back up with enter password,I did this 4 times before I gave up.

This was'nt even wireless it was connected by eithernet cable. :wacko:

is it a WRT54GL?

 

have you set it up before with a password, it may be a good idea to reset to factory defaulkt settings - if its the one above hold the rest button on the back in for more than 5 sec if not check the manual

[Justice]

I reset the button on the back and started the setup again, I got all the way to entering IP addresses etc and then it said it was lloking for internet conection after a while a box appeared and said no conection found.

 

The ip etc I put in were what I found on the conected dialog box on the conection i am using now or are they different ?.

[NikpV]

some progress anyway

 

working a bit blind here without more detail - exact model would help + title on the tab of the dialog box

I have to assume you have connected the router to both the pc (yes) the phone line or other router connecting to the internet (thats why I need the model number)

 

have you set up the internet connection settings as supplied by your isp is this dialog box "basic setup" or "network setup"

 

The ip etc I put in were what I found on the conected dialog box on the conection i am using now or are they different ?.

 

what type of connection are you using - are you connecting through a router an adsl modem or what, does your isp assign you a static ip address, or a dynamic address,

on a linksys the ip address is usually 192.168.1.1 the username and password admin, not always the case though.

 

It helps if you turn of detect settings automaticaly in tool>internet options>connections>lan in order to get a connection.

 

Sometimes having an existing dial up connection will hinder things also as well as ensuring under general>settings ensuring you set update pages every time (or something like that).

 

If I Remember correctly once in the linksys setup you must set the DSL connection to RFC 2364 PPoA multiplex VC, QOS type UBR,then type in your username and passwor. OH and virtual circuit should be 0 over 38

 

If this is the type of settings it asks for give me a shout and I will go though all the others with you,

 

hint, disable router firewall and all other protection till you get it online then set them up

[NikpV]

trouble is with the info given I can't see how the router is connecting to the internet, apart from cable modems I can't find a linksys wireless - G router with built in adsl modem so whats making the connection - is justice using an ethernet based adsl modem or a usb type - not enough info yet

[Justice]

Thanks guys

 

I will try the things you mention later on today.

 

Just to add a bit more info

 

Model is WRT54G 4 channel ethernet router with wireless

My internet provider is Blueyonder telewest

My laptop is a Dell Precision M70

 

When I conect to the router and go throught the setup the icon in the task bar says I have limited conection at this stage I am not trying to config wireless.

 

Will post later to update my progress. :P

ok - I set up a wireless router on blueyonder for my mil about 6 months ago - and boy I remember the 'Limited connectivity' - I've set up a few networks for friends etc but I couldn't solve this problem - in the end I had to phone their tech support. It was solved using some obscure command (to me at least - network gurus will probably know) in dos, unfortunately I can't remember it. After sorting that out the rest of the setup went like a breeze :D

 

when you right-click the icon on the taskbar and select status, click on the support tab, you should have

 

ip address 192.168.1.??? in the top box where ??? can be a number between 2-253

subnet mask 255.255.255.0

default gateway 192.168.1.1

 

this bit is all about the computer communicating to the router if this is all ok then you need to get the router set up to talk to blueyonder - this is where you need the info from your present connection

[mumble_bee]

dunno if I'm too late here, or its too late where I am :S

 

after setting up a couple of cable setups EXACTLY as the manuals said, I realised twasnt the way to do it.

 

if the following is irrelevant, I do apologise.

 

what worked was stupidly this :

 

switch on the cable modem, so that the only dangly things going in are the power and the cable wire thingy

after say 45 seconds (once all the flashy lights have settled down) connect the router via ethernet.

It doesnt matter if the pc is connected to the router or not at any stage.

 

surprisingly that works...

 

I spent ages with the old routine of mac address spoofing - apparently thats not the way anymore.

the above works for me now.

[Gteuk]

Ah the linksys access point, Pain in the a$$ to install, I just removed ours in the office due to lack of security make sure your firewall is set up, 9/10 times when you set up the security it blocks everything. took me 3 days to secure it from external users,. ;)

 

all better now with WAG354G model which has better software
