Solved how to secure my network connections

November 29, 2011 at 07:37:24
Specs: Windows XP, Pent4/2ghz 1gb
My itty bitty manual just shows on how to hook up my router via cable modem...nothing on how to secure it. I go into setup of the router and see where one can add info but am at a loss what to enter. I tried, merely by guessing, applied the info, and screwed up my networking. I couldn't even get into my router to revert back, cause i couldn't get on line...finally i reset manually my router and all is well again, except when i see a list of nearby network users, mine is the only one that says unsecured.

Setup of a wireless router should always be done using a wired connection.
If you want to use WEP then do so. You will need to set up an SSID. That is your network name. Call it George if you like. It makes no difference. Broadcast the SSID.
Next select the encryption standard. I use 128 bit. Then set the key sequence number. Select number 1.

Now make up a 26 character HEX key. random combination of the numbers 0-9 and lower case letters a-f Enter that in the boxes and write it down because you will need it later when you try to connect your wireless device. Save this and exit.

Now try to connect your wireless client device ( PC/laptop etc) It should detect your wireless network ( George) and prompt for an encryption key or passphrase.
Here's where you enter the 26 character HEX key. If it still won't connect you may need to go into advanced connection settings to make sure your device is set to connect on the same key sequence number (1) and using a shared key.

If you cannot get WEP to work for you and your client device is WPA compatible you can go back into the router admin using your wired connection and change to WPA. I believe with WPA you are basically unrestricted on what you can set as a passphrase and accessing from compatible client devices usually needs no advanced setup options. Simply enter the required passphrase.

Let us know how you get on.

Unfortunately my router is a generic bought in Compusa 6 years ago and going strong. Has no model number that would matter, i guess, and do not know the maker. It seems each time I attempt to tweak the security area from what I have read, it disables and then i have to reset it to get back on line...the last time, resetting didn't work at all, so i went back to my wired connection and that is how i am able to write this now.

I am of the old school if its not broken keep it...and its certainly not broken...just the stupid manuals these days that leave out some necessary information on security. its working just fine on a wired connection now, except for the security issue and i am sure when i get some time it would work again wirelessly...but again, unsecured. Would be nice if someone who knows about security setups would respond.

I was emailed to choose the right response for my problem here...how can I...when it has not been resolved? All i get is go buy a new router....all i need to know is what exactly does one enter in those boxes that ask ....there is Hex and letters Hex i found out is 0-9 and letters a-f but i see more characters than that...my manual says for cable modem best leave it to default....but doing that does not give me a secure mode. When I enter a WEP or WPA i am asked to enter Info in the those empty boxes...Like what? P.S. My router is not broken.

wep and wpa have been hacked. only wpa2 is still secure.

How many wep characters depends on the level of encryption
NOTE: 5/13/16/29 characters are needed for 64/128/152/256-bit WEP

You can easily google the wpa character lenght vs bit encryption level

"I am of the old school if its not broken keep it"

This is not a perspect that is applicable to computing. Old means unsecure/open to being hacked/slow/obsolete.

I use building methods that are 100s of years old along with equipment my grandfather used. Certainly does not pertain to modern day computing.

You recieved professional advice. If you don't want to follow it that is certainly your choice and your risk.

Wow..finally a very instructive response..albeit i appreciate all who respond, but yours goes into the very detail I have been searching for...up to a point. I am network ignorant, as you probably can tell by my posts. From tweaking my router setup to make it secure, I got held up when i tried to get on the internet that i needed the WEP key...Now, correct me if I am wrong..according to your post,.i can enter any number of Hex or letters, and that should let me in? I couldn't even get my wired network to open in order to get at my router setup and just get rid of the WEP info and go to default.....but as i am able to write this now, I was confronted again with the box to enter the WEP info and i made a copy of an earlier successful connection where the WEP key is shown almost a 100 characters including numbers and letters. Again not knowing what i am doing at this stage i just copied the first 10 or 15 characters of that 100 characters, entered it in that box, and i got through finally...but i now notice that the network icon on my task bar is showing a yellow exclamation point. The info on that shows that i am getting excellent signal strength but limited or no connection.. so i am not out of the woods as yet i presume.

Use this website to help you generate a random WEP key and then copy down the ASCii and/or HEX output. Just generate a key to match the encryption level you have set in the router. eg 128bit.
http://www.andrewscompanies.com/too...

As wanderer said "NOTE: 5/13/16/29 characters are needed for 64/128/152/256-bit WEP " Those numbers of characters 5/13/16/29 are for keys entered in ASCii format. For HEX the numbers are 10/26/32/58

So if you use 128bit WEP then your HEX key has to be 26 characters long.

Thanks again Richard...My router shows WEP,WPA-pre-shared key and WPA Radius...i understand they are more effective than WEP..for security .does those keys you've mentioned apply to either one of those? I do not see anywhere from the encryption box a 128, only 64. WPA Radius, if i choose asks me for a server ip address and a Radius password

I don't know anything about WPA radius. I have several devices in my home that are only WEP compatible so am reasonably confident in the setup for that protocol.

Suggest you use WPA PSK. The setup for that is fairly simple. You use any passphrase you like. The more complex the better. This presumes your wireless PCs are WPA compatible.

I would be surprised if your router is only 64bit WEP capable since it has the other more secure protocols as well. If you select WEP does it then show a drop-down menu to select other WEP options?

As a matter of interest, when you go into the router admin interface ( presume by entering 192.168.*.* and using an admin login & pwd) ) is there anything in the user interface to identify the make/model of the router?

Sorry Richard, your right i did find 128 with that drop down arrow...this setup is getting to me i'm sure this is simple for those that know about networks but for a beginner like me..its intimidating to say the least. What set this all off after reading the cd guide that came with this router, they recommend if i have cable modem just set it to default....which i did and had no problem, cause i did not have to enter any info like Hex and etc..and passwords, but it was not secured. But i finally wanted to make my setup secure and that is where everything went out of whack for me...but i think i am getting there thanks to you. Wanderer said that WPA2 is the safest for now better than wpa...and i do have WPA2 with 64 encryption but it shows one box that is asking for a PSK number

PSK means Pre-shared key.
That is the passphrase that you make up. It does not need to be in either ASCii or HEX but can be plain language mixture of any alpha/numeric & non-alpha/numeric characters. Basically any character your keyboard can produce.

It is only WEP that requires a key in the specialized format.

My ipconfig does not show a default gateway address and I am reminded of this each time i try to use my wireless. My wired connection does show the 192.168.X.X gateway..which it seemed to have done automatically, but not my wireless. i searched the setup of the router and could not find any area where one enters that info...although i did see it listed automatically in my Lan IP and D HCP server...so i do not know if they are connected in any way. Could I ask you a question about your setup WEP? Is it secured? If so, how can i go about it with my setup...? I had no problems when it was set up as WEP, but everyone says its old and weak compared to the latter ones..ie WPA...plus the fact i seemed to screw up that setup whenever I try to secure it.

wep and wpa have both been hacked. they even have youtube videos of how to do it. only wpa2 is secure. wpa radius refers to having a radius server handling authenication.

if you aren't getting a gateway ip review your dhcp server configuration. otherwise post the results of a ipconfig /all so we can see what is going on.

Are you using a single PC for both the cabled LAN connection and the wireless connection? Did you disconnect the LAN cable before attempting to connect wirelessly?

It may even be helpful to reboot the pc after disconnecting the LAN. I'm not sure Windows would accept more than one gateway entry. Your IPCONFIG results clearly show the LAN connection working.

Once you get the wireless running you should get the 192.168.2.1 gateway entry in the wireless NIC.

And as for whether my WEP is "secure" . Unfortunately for me I have to use WEP as my children have Nintendo DS which are old enough not to be WPA compliant.
I do this in the knowledge that a hacker may park their car in front of my home and break into my network. I have the options in my router to enable MAC filtering and a number of other filtering options which would prevent an un-registered device gaining access. So while the WEP might be vulnerable, any hacker would also need to spoof a registered mac address in order to get any further. If you live in an apartment complex with lots of close neighbours then the odds of someone trying to access your network are much higher.

Well i am networking between my desktop and net book...both of them have the options of wired and/or wireless. By Lan cable, you mean 'ethernet" cable? If you do, i never had disconnect it ..for a time i was able to use both when my desktop was unsecured, but usually disable one or the other, never both on at the same time. When I first setup my network, the instructions said to connect a ethernet cable from the router to my desktop...never read anywhere that one has to disconnect that cable in order to use a wireless connection.. But I will give it a try at this stage. LOL

usually you don't disconnect physically. you just enable/disable in lan connections by a right mouse click you get the options.

Appears to me your wifi isn't connecting due to encryption.
might start with no encryption on the router and your pc to get a connection. Once you have that build from there.

I too suspect that and i did have it setup originally like that...and like i said in previous posts here, it wasn't secured. Now, as far as getting it secured, to my limited knowledge i thought encryption would make it so. The key is to find the right one. WEP makes me nervous, although Richard says he has it that way. the only others i have left is WPA2 and WPA radius...and i am now using WPA 2 and it does show that it is secured, but for some reason it cannot find my network address.

HI all i think my problem is solved finally. I just want to mention what i did to correct my problem, which surprisingly, no one mentioned here. It was right under my nose all the time....it has to do with my OS XP....I went to properties of my network wireless connection, and clicked on the box which was opened "obtain IP address automatically" and that did the trick. I hope this would be helpful to anyone else that had the same problem...all this time i kept looking in my router configurations, when i was able to. Now, that it is setup the way I want it, secure and all is there a way that i cam make a copy of my settings and which ones, so in the event my pc should crash, and i have to set up the network again...hate to go through this again.

according to your ipconfig your wireless was already set for obtain ip automatically so this isn't what fixed it.
