Security Settings Problem w/ WRT54GS

I recently had to reset my router, and after a few initial problems with setting everything up again (had to change the routers default IP address from 192.168.1.1 to 192.168.1.2 to get it to work)... I've now hit another roadblock I can't figure out.
Every time I activate any kind of wireless security, (I've tried both WEP and WPA) I lose access to the router and the internet.
I end up having to reset the router and start all over again just to regain access to the manual configuration interface... so I can then change the default IP address to 192.168.1.2... so I can get on the internet again.
I don't recall having this much trouble last time I set this thing up... I need some help please.
Thanks!
Dell XPS running Windows XP (SP3)

Disconnect the modem power cable and log on to the router...You need to change the router IP to 192.168.2.1 instead of 192.168.1.2...After that power cycle your router for 1 minute...Open the set up page of your router using the new IP(192.168.2.1)...Click on Wireless tab...change the Network Name (SSID) to a new name...change the channel to 11...and click on Save Settings...
To enable Secuirity follow this and then try to connect to the Wireless Network on the Wireless Computer...

6500 classic - security settings problem

I have Nokia 6500 classic and I have a little problem with it. When I go to the Security settings menu Security module settings is not active. When I push on it it tells me to Insert security module. Can someone explain to me what should I do because there is nothing in the users manual about the security options.
Thank you in advance!!!

If you don't have a security module (not many people do) then you will never need to use this option.
Security modules are expensive and are used by certain agencies that need heavily encrypted lines.

Changed Security settings, now cannot connect

Hi,
I was trying to increase my security settings on my WRT54G v. 8 and somehow have messed up my connection. I updated the MAC settings so that only my computer has access, and I tried to change my WEP from 64 to 128 bit. I now realize I should just change it to WPA, since it is much more secure. Now my wireless is not working, saying limited or no connectivity because it couldn't assign a network address, I believe (It looks like I don't have an IP address??). When I use my wired internet and type in the default wireless IP address, it says that the connection is not valid or some such thing (sorry, I am not on my home computer now) and I cannot get in to change the settings again. Do I need to reset the router and reset all my settings? How can I reconcile new security settings with my computer? Thanks!

To set up wireless security, you must use a computer that is wired to the router.
Where to find the router settings: The router's login password is usually on one of the "Administration" pages. The other settings are all found in the "Wireless" or the "Security" section of the router's setup pages, located at 192.168.1.1
First, give your router a unique SSID. Don't use "linksys".
Make sure "SSID Broadcast" is set to "enabled".
Next, leave the router at its default wireless settings (except for the unique SSID), and then use your pc to connect wirelessly to the router. Test your wireless Internet connection and make sure it is working correctly. You must have a properly working wireless connection before setting up wireless security.
To implement wireless security, you need to do one step at a time, then verify that you can still connect your wireless computer to the router.
Next, encrypt your wireless system using the highest level of encryption that all of your wireless devices will support. Common encryption methods are:
WEP - poor (see note below)
WPA (sometimes called PSK, or WPA with TKIP) - good
WPA2 (sometimes called PSK2, or WPA with AES) - best
WPA and WPA2 sometimes come in versions of "personal" and "enterprise". Most home users should use "personal". Also, if you have a choice between AES and TKIP, and your wireless equipment is capable of both, choose AES. With any encryption method, you will need to supply a key (sometimes called a "password" ).
The wireless devices (computers, printers, etc.) that you have will need to be set up with the SSID, encryption method, and key that matches what you entered in the router.
Retest your system and verify that your wireless Internet connection is still working correctly.
If you have trouble connecting, in the computer, go to your wireless software, and go to "Preferred Networks" (sometimes called "Profiles" ). There are probably a few networks listed. Delete any network named "linksys". Also delete any network that you do not recognize, or that you no longer use. Delete your current network (this will remove any old settings). Reboot computer. Return to "Preferred Networks" and re-enter your current network info (SSID, encryption (if any), and key (if any) ). Then select your current network and make it your default network, and set it to automatic login. You may need to go to "settings" to do this, or you may need to right click on your network and select "Properties" or "settings". Reboot computer. You should reconnect automatically (it can take up to two minutes). If you still have trouble, temporarily turn off your computer software firewall.
And don't forget to give your router a new login password.
Picking Passwords (keys): You should never use a dictionary word as a password. If you use a dictionary word as a password, even WPA2 can be cracked in a few minutes. When you pick your login password and encryption key (or password or passphrase) you should use a random combination of capital letters, small letters, and numbers, but no spaces. A login password, should be 12 characters or more. WPA and WPA2 passwords should be at least 24 characters. Note: Your key, password, or passphrase must not have any spaces in it.
Most home users should have their routers set so that "remote management" of the router is disabled. If you must have this option enabled, then your login password must be increased to a minumum of 24 random characters.
One additional issue is that Windows XP requires a patch to run WPA2. The patch is located in SP3, so you will need SP3 to run WPA2 in Win XP. Vista already supports WPA2.
Note:
WEP is no longer recommended. The FBI has demonstrated that WEP can be cracked in just a few minutes using software tools that are readily available over the Internet. Even a long random character password will not protect you with WEP. You should be using WPA or preferably WPA2 encryption.

Unable to change wireless security settings on WRT54GS v5.1

I'm using a WRT54GS v.5.1 with the latest firmware (v1.50.9).
Set this up this weekend - all was fine until last night when the router stopped broadcasting the signal. I've reset the modem countless times and powered it down and back on again.
The router is now working fine - but I'm unable to change any of the wireless security settings. When I try to change the setting under Wireless > Wireless Security to WEP, it just jumps back to Disable and no changes can me made. Same situation when trying to enable a Wireless MAC Filter?
Any ideas? I don't want to use the router without any security in place!

you can try to upgrade the firmware of your.
try this link :
http://linksys.custhelp.com/cgi-bin/linksys.cfg/php/enduser/std_adp.php?p_faqid=557&p_created=108421...
make sure to select the correct model and version of your router. if you cant see the model # of your router as one of the downloads, you will need to have the router replace (hope you'll not).
hope this help.

I changed my WRT54G security settings from WPA to WEP

I changed my WRT54G security settings from WPA to WEP and now one of my latops (Dell 5100) will not connect wirelessly. It is using a linksys wireless-B notebook adapter. I am at a loss at how to reconnect this to my wireless network.

Go to the setup page of the router on the wired computer and click on the Wireless tab,check the network name(SSID),change the Wireless Channel to 11-2.462 GHz,Keep the SSID broadcast enable and click on save settings...Click on the subtab Wireless Security and change the Security mode to WEP or WPA as per your requirement.If you are using WEP then,note down the KEY1 as the network key(case sensitive)...
Now,on the laptops,delete the preferred network and then,try to connect the Wireless Network.

Best Wireless Security Settings-WRT54G Linksys Router

I've been running into problems attempting to set the wireless security settings for my router and then trying to connect to the internet from my iBook. As long as I enable SSID broadcasting I can find my router but the problem starts when I enable the security settings. The iBook will then ask for the password and nothing I've inserted works??? I'm at a loss. I've given up, those sorts of brickwalls can do a number on your head--major headache this weekend..so I will try again tomorrow. I thought the passphrase is your password--the only thing that I haven't tried (after searching the forums here) is putting the $ in front. Does anyone have this particular router that can give me some suggestions (in basic, simple terms please) that can help me get started on a good security setup so that I won't be scared someone in the neighborhood (as I've read previously) is scanning and can log onto my internet connection. Thanks!
iBook G4 Mac OS X (10.4.5)

Why in heaven would you want WEP to secure your network when you can have WPA which is more secure and doesn't have this kind of problems???
With the right tools (available free on the net) you can crack almost any WEP protected network in less than a day (I have done this with my friends to prove them how weak WEP is).
So imagine you set your WEP protected network, a neighbor crack it and use it, all of this while you CAN'T use your own network.
You should try WPA, good luck...
BTW: I have the same router, with WPA and SSID broadcast disabled.

Problem with email setup in iPhone after changing to secure settings

When changing account settings to use Verizon's new secure email settings, my iPhone keeps giving error " Can not get Mail, the mail server incoming.verizon.net is not responding.
I am using port 995 with SSL as instructed. Switching back to the standard port 110 with no SSL works fine.
Outgoing works fine with port 465 and SSL.
Also, same secure settings on Outlook 2010 work perfectly fine.
Anyone having this issue?

A few other people have posted that after making the changes they had to reboot their iPhone/iPad in order for it to connect again. Have you tried restarting?

Problem with security settings

Dear all,
We have the problem that we create a PDF with CS3 (compatible down to Acrobat Reader 5) with no security settings.
This PDF is sent out to a colleague who's only having an Acrobat Reader installed on his computer. When he's checking the security settings, there are several security settings done. He urgently needs to comment things.
Please help. We are desperately seeking
Thanks a lot in advance!!!
Birgit

Hi Bernd,
Thanks for the quick reply! And: of course there is no Acrobat Reader As everyone around me calls it like this I just wrote w/o thinking about it. Sorry!
I passed your answer to my colleagues searching for a solution. Obviously they made the right settings but the other side using the Reader had a too old version in which commenting was not possible, yet.
Hmm, all this hustle for no reason...
Anyway: thank you very much for helping!
Take care,
Birgit

Problem with SQL Security Settings

I've run into an odd problem since moving to ColdFusion 8
Enterprise Edition. Any text string submitted to an action page
through a form will return an error ("Executing the SQL statement
is not allowed.") if it contains text that conforms to a disallowed
SQL command. For example, I've turned off the "create" as an
allowed SQL statement in my datasources. If I submit a form that
includes the following text, "Go back to the beginning of the
document; create a title," I get the error message. This occurs in
richtext form fields as well as in standard input form fields. If I
turn off the security setting so that "create" is an allowed SQL
command, the error goes away and (fortunately) no table is created.
It appears that ColdFusion is checking for the presence of
illegal commands even in text strings that are delimited by single
quotes in a query -- and even when those text strings wouldn't
actually do anything to a database.
Has anyone else run into this? Am I missing a setting on my
Administrator? Or am I missing something obvious? I'm not pleased
about the options I have at this point -- turning off some of my
security settings or allowing errors to occur and telling people
not to use semicolons as a workaround.
Thanks for any help you might offer.
Mike

Are you using <cfqueryparam...> tags? It sounds like
you are directly
passing the form text into the SQL statement. If this is what
you are
doing, then you are probably getting the expected, safest
results. If
you do not use the <cfqueryparam...> tag to tell
ColdFusion and your
database that this is a bound parameter then it is possible
that the
text is expected to contain SQL code and it will be parsed as
such.
To give clearer advice it would be helpful to see an example
of your code.

I downloaded a security update & when i tried to open firefox afterwards ,I couldn't open it. have a DEP settings problem i tried to change my computer's DEP settings but was notified i couldnt for firefox,what should I do?

I was prompted to downloaded a security update & so I did. when i tried to open firefox afterwards ,I couldn’t open it. My computer told me I had a DEP settings problem.I tried to change my computer's DEP settings but was notified i couldn't for firefox. I tried the uninstall & then install Firefox again route (could not even do it in safe mode since i can't even open firefox)but still had the same problem afterwards. What should I do?

Do a clean (re)install and delete the Firefox program folder (C:\Program Files\Mozilla Firefox\).
Download a fresh Firefox copy and save the file to the desktop.
*Firefox 10.0.x: http://www.mozilla.org/en-US/firefox/all.html
Uninstall your current Firefox version, if possible.
*Do NOT remove personal data when you uninstall the current version or you lose your bookmarks and other data because all profile folders will be removed.
Remove the Firefox program folder before installing that newly downloaded copy of the Firefox installer.
*It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
*http://kb.mozillazine.org/Uninstalling_Firefox
Your bookmarks and other profile data are stored elsewhere in the Firefox Profile Folder and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.

Problems with security settings and itunes updates! What do I do?

So I preordered a cd that became available today. When I went to download it, a message came up saying that I need to download the latest version of itunes (7.-[can't remember the last part]but anyways) so I clicked on the upgrade icon. I then got a message saying "your current security settings do not allow this." No matter what I do with my security settings I keep getting this same message! I have windows xp, please help I would really really like to be able to download and listen to the cd I've paid for! Thank you in advance!

Maybe you aren't on an admin account in Windows? If not, create/logon to one and install it.
Or maybe you just need to go to the website and download it instead of updating through iTunes. Go here:

"Your browser security settings don't permit the editor to automatically execute copying operations. Please use the keyboard for that (Ctrl/Cmd+C)."
Please advise.

I'm confused about security settings for WRT54GS!

So I enable G only, rename the network from linksys and save settings, then I open security settings, select WPA2, enter a password and save settings. Now when I return to the wireless setup page do I have to hit the SES Lock icon? When I do that it changes the name of the network. If I don't hit that key my laptop still lists my network as a secure network. If I hit that key then I believe it renames the network differently everytime, thus disabling auto login with the laptop. I've had a wireless network in this house for over five years and have never found anyone but my adult children's laptops, my laptop and the desktop in the clients table, so I'm mostly experimenting here but would like to know how to do it, especially relative to the SES icon. Thank You!

SES - Secure Easy Setup. You never use this until you have read the manual to understand what it does.
SecureEasySetup is a special feature on Linksys devices that it automatically assigns your wireless network a unique wireless network name or SSID and secures your wireless connection with a push of a button. It secures your wireless connection by enabling WPA (Wi-Fi Protected Access) on your access point.

Problem with security settings on wireless network

I swapped out an old D-link router for a new D-link gigabit router and am now unable to get the security settings to stay on WPA2. I can set it okay, but the padlock doesn't show up next to the network name and when I go back to system preferences it has reverted to "none" under the security settings. Any suggestions??
