Wireless security problem

I have a linksys wrt54g ver.6 wireless router. My Dell laptop running vista can connect wirelessly to the internet just fine when I have wireless security disabled on my wrt54g router.
When I enable security (I tried WEP) the network connection on my laptop fails and I see this message in vista’s “Connect to a network” window:
"The settings saved on this computer for the network do not match the requirements of the network"
Any ideas on how to fix this? Thanks!!!

Hye there,
What you can do is change the security mode to WPA Personal..
Because sometimes Vista doesn't really support WEP mode...
Lets give it a try....
Thanks...

Wireless Security Problem (PC Laptop)

My PC laptop will connect wirelessly whenever I create an unsecured wireless connection; however, whenever I enable the wireless security feature; it no longer connects to the internet (0 bytes received). Any thoughts?

Hello Tesserax,
Thank you for your reply and assistance. I was able to resolve this issue by updating my wireless adaptor driver. I found another user on my laptop's support website that had the same issue. I'm FINALLY... utilizing my wireless internet .
Best regards,

New iPhone 5 wireless security problem

I have just discovered hat I cannot use several PC and Macbook devices on my wireless network if I am using WPA/AES security. I have turned security off completely and all works ok and tomorrow when I have hours to spare I will try WEP. Can this really be true? Can Apple really get things so wrong? Does anyone know of a way to fix this this and use WPA?

Sorry - I should have said this only happens when I connect my new iPhone 5!

Problem with wireless secured network in hotels

Hello,
I'm a cabin crew member and I travel around the world almost every week. Since the update ios 6.0, my Iphone 4 16 GB doesn't connect automatically on the wireless secured network of hotels, while it worked before the update in the same hotels. My Iphone still connects automatically on my own home network, but I must ask every time to the help desk of hotels for manually connecting, by registering my mac adress on the router. Problems in Japan (Tokyo), USA (New-York, Washington, LA) and Senegal (Dakar). I'm really upset and Apple seems not concerned. Please help me.

Welcome to the forum.
I'm not so familiar with Linux, though've installed and dealed with some distrs, but as far as i know they're mostly compatible with each other.
So, check this forum (though it's Ubuntu) and try to find solution there, if no one here helps.
Also there's a member here called wyth, which helped some Ubuntu-users, which was great. Try PM him if no help here or on that forum.

Connecting laptop to WRT350N and wireless security

Hi, I have the following problem. I need to connect a laptop to WRT350N router. Everything works OK if I do NOT use wireless security. If I use PSK (WAP) then at the Preferred Network screen I set the settings to WAP/PSK and enter the shared key. However, this setting is overruled again and again. I can not save it. If I select my network from the networklist, many times the laptop doesn't even ask for the shared key. And if it does then it acts as if I have installed WEP on the router (which isn't the case!). I use Windows XP Home. Does anyone know what the problem is and how to solve it? Many thank, JFX

I have a second laptop connected to the router which works ok with both the non-secured and the WAP/PSK-secured environment. The one that is not working is a Sony Vaio with LAN-express AS 802.111g card for which I have the latest driver installed. For the WRT350N also the latest firmware installed (WRT350N v2 firmware 2.016) JFX

Running WPA Wireless security w/ OSX 10.2

I am running an older G3 iBook on my wireless system and it does not seem to work with WPA wireless security. I am using a Netgear G614 router, which works fine except with the iBook. The iBook has no problem with the wireless security turned off and I would like to avoid using WEP, if possible. I posted this in the older OS sections with no response. Help!

I have a similar problem with which I've been struggling for months. My MacBook Pro suddenly stopped working with my home router - it showed as connected but would not browse.
I have eventually boiled it down to a problem with WPA security. Ethernet networking works, networking with WEP security and no security works, but WPA doesn't. This applies to any router, not just mine at home.
When it originally failed, my MacBook was running OS X 10.4.11. Rolling back to 10.4.9 and before removes the error, but 10.4.10, 10.4.11, 10.5.1 and 10.5.2 all exhibit this failure. The fault is not evident on my iMac G5 or my new iMac Intel, or on my daughter's XP PC.
Therefore, it is a combination of hardware and software issues. So don't expect a cure just by upgrading!
Does anyone have any ideas for a cure, please?

WRT160nV3 wireless security repeatedly disabling

I have the WRT160nV3 and am having a problem with the wireless security. I set up the wireless security but everytime I notice the signal slows down or I get dropped I go to check it and it shows the security is disabled. Sometimes other people are there so I remove them, and ENABLE AGAIN. After that it seems to work fine.
I have had to do this multiple times. After Enabling I have saved the settings everytime but it happens all the time now. Does anyone have any insight? Your help would be greatly appreciated.

Hard reset the router by pressing the reset button for 30 seconds and release. Wait 10 seconds and power cycle the router. Connect via wired computer to 192.168.1.1 username blank, password 'admin' and reconfigure the router from scratch. Now check again.

WRT54G Wireless Router Problem. Need Help!

I'll start with the basics of my situation and if more details are needed, I will provide to the best of my ability.
I have a comcast cable internet connection. I have 6 computers in my house. Two of them are downstairs (which is where our modem is.) The other four computers are upstairs. All of these computers are Desktop computers with the exception of one laptop.
My laptop (which is Windows XP) can pick up a random wireless signal from the room it is in. I also found out a way to share the internet connection on the computer by going into the properties of my network connection and enabling internet sharing on it. This means if I connect a network cable from my laptop to another computer, I can leech the connection from my laptop and have internet access on the other computer. I also had a switch that I used to connect the other 3 computers upstairs by means of the laptop. The problem was, the laptop was using someone else's wireless connection in the area, and it wasn't strong enough to keep up a constant connection.
I decided, if I can leech someone else's wireless connection, why not have my own. So i recently bought WRT54G Wireless Router and set it up on one of the computers downstairs (because that's where the modem is). It works fine as far as connecting my laptop to the internet from upstairs. My laptop can access the internet through the connection I set up in the LELA program.
Here is the part I am confused about. Everything is plugged in correctly as far as the router is concerned because the laptop can access the internet. But when I connect an ethernet cable directly to one of my other computers (which are Windows Vista, but I didn' t have a problem with it previously when I was leeching someone else's connection), the connection drops on my laptop, and the other computer still can't access the internet. A notice pops up that says its trying to identify the network, but it gives an error that says there is something wrong with the DNS. As soon as I disconnect the ethernet cable connecting my laptop to one of the other computers, the connection is fine again on the laptop. It's only when I connect the computers together that the connection drops.
I just don't understand why it wouldn't work when I created my own network if it worked with another network with no problem. My whole point in getting a wireless router was to have a router within good range to keep up a constant connection on my other computers that aren't in range of the modem downstairs. I just don't know where else to look. I'm not sure if it can be fixed on LELA, manually through my wireless settings, or if it could be a problem with one of my computers' settings. I've tried many different things and I'm not sure what else to do so any help is most definately appreciated. I feel like I've tried everything. I know it's possible because I've one it before, I just need the help because I'm not much of a networking person and I don't know what I should start with to make this work.
Thank you to anyone who can help or even point me in the right direction.

Facetime works with wireless security disabled, dropped otherwise

On a D-Link DIR-615 wireless router, configured as an access point.
Security mode: WPA-Personal
WPA mode: WPA2 Only
Cipher type:AES
I tried inserting a 1.3 Mb file, to no avail.
I have an iPad mini with OS 8.1.2
Please let me know if more information is req'd.
To have facetime with my son and grandchildren I have change the security mode to 'none' during the session! Really? If I do not, we have about a one minute session that is dropped.
Any ideas will be explored!
Thanks in advance,
Grandpa Pete

Three answers:
1-The router is an access point as it is a 'slave' to the wired router. The wired router assigns the ip addresses and is connected to the Comcast-Arris modem.
2-Security mode options: None, WEP, WPA-Personal, WPA-Enterprise and
the password options are Auto (WPA or WPA2), WPA2 Only, WPA only. I chose the WPA2 only as some other place I'd seen something about a problem with the TKIP cipher. I'm a novice, though. What you're suggesting makes sense and I'll try to go to WPA only.
3-I tried inserting a file showing the wireless router setup page, via a screen shot. I can't even insert a half Mb file, for whatever reason. The error page says to keep it to less than 2 Mb.
-As above, the wireless device must be an access point. It's in the living room, where wireless devices are mostly used. The wired router is in one corner of the house, with the main winxp pc.
-I can't make the wireless router security mode WPA2, so I used WPA for everything and see if it works for the next facetime session. All the other wireless devices are now functional.
-I'm not understanding the third option. Is that for my tower, each wireless device?
(No, winxp is not a joke. I use it as my main pc os and have no need to replace it. I'm posting my problem in this forum because we now have an apple product, the mini iPad, and I'd sure like to use it for the facetime with the wireless security setting on during the session. So far, it's REQUIRED to turn the wireless security off to keep the facetime session longer than about 60 seconds.)
Thank you very much for your time! I really appreciate it. As a novice, routers are still mysterious to me, what with all the settings inside of them.

btw: my question is not solved. Not at all! I still believe I have an unsolved question. I don't know why the green box and checkmarks exist! Did I miss something?

Wireless Security

Right now, I have no wireless security. If I were to have one, which setup/system would be the best of the choices offered in Airport utility? I noticed there are a number of networks(due to different names) in my area. How can I make sure, no one else other then my family members can use my network or maybe they can't even though I do not have a security setup? My daughter has been saying her network connection is slow. I have no problems-no slower or faster then usual. She thinks she is connected to another network. Is this possible? I have lowered the range of my network to #10 which is the lowest strength. I want to make sure no other person then members of my family can connect to our little, family network.

Use the strongest password security that you can. This means both choosing WPA2 (if your computers can support it) and a good strong passphrase. Since any decent OS (Mac, Windows or Linux) has something like the Keychain, it's not like you really need a passphrase you can easily remember...you'll never have to type it in (One written copy locked in you fireproof safe with you other important papers might be OK, though). Giving your network a unique name (SSID) doesn't hurt either, since it is used with the passphrase to generate the encryption key for the network. And make sure the router itself is also password protected - no point setting up all that security only to have some neighbour just reconfigure your router when you aren't looking.
Don't use WEP unless you have to (actually, given the choice between using WEP and upgrading my computer, I'd upgrade). It's broken and effectively no different from using no security at all. MAC address filtering and using closed networks similarly have no security benefits. There might be some administrative efficiencies to MAC address filtering, but no security benefits.
Set up WPA2, turn up the power on your router, make sure all the computers that are going to connect are set up with the passphrase (and maybe clear them of any other networks they remember) and you should be good to go.

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!

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.

Ethernet active, airport also active... how to stop this security problem.

Im not sure if anyone else is noticing this but this is becoming a problem in an enterprise environment.
In the "Network Port Configurations"
I have "Built in Ethernet" as the top, then Airport below that.
The problem is that when the Ethernet is working (active) AND the airport is turned on and connected to a network it is ALSO active, grabbing an IP# and essentially bridging the two networks.
I have tested this many times and it works every time.
For example:
My MBP is connected to the LAN using Ethernet, and traffic is going through the Ethernet and has it's own IP (192.168.0.104) given by DHCP. If I turn on Airport and it finds (and connects) to a network (for example... Linksys? LOL) it will also grab an IP from that Airport network.
Now... if any services (AFS, Windows Sharing, WebSharing..etc) is turned on, you can access the MBP from EITHER network (Since the Airport grabbed and assigned an IP)!!! Even though in the "Network port configurations" it is setup to use the "Built-in Ethernet" first, if it can't find that then use Airport... BUT from what I can see this ONLY applies to Outgoing traffic and not necessarily both incoming and outgoing. It is essentially bridging the two networks
I cannot find a way to prevent this network security gap automatically. (If Ethernet is active then do not connect to any airport network, even if it's in my preferred list or an open network)
Another side effect...in an office environment which has Wireless services on the LAN, if your Airport is turned on and your using your Ethernet connection, your computer is using up 2 IP#'s out of your DHCP pool!
Anyone else having or notice this problem?

If I turn on Airport and it finds (and connects) to a network (for example... Linksys? LOL) it will also grab an IP from that Airport network.
And why would you do this? If you are connected to the LAN through the ethernet port why turn on Airport too? Or why have your Mac connect to an unknown WLAN by default?
When I take my MacBook to school I only have one connection active. On my Mac Mini that is running MacOS Server I have both ports enabled but I guess this is not the most common situation.
Now... if any services (AFS, Windows Sharing, WebSharing..etc) is turned on, you can access the MBP from EITHER network (Since the Airport grabbed and assigned an IP)!!!
People will be able to access your /Library/WebServer/Documents/ folder (or any of the users web documents folder) but that's not a security problem unless you have changed (and messed up) the default Apache definitions, changed the web server documents ownership and/or permissions or have some problematic PHP code or CGIs. As for AFS, Windows Sharing or FTP people won't get into your Mac unless you have and empty password or they know your password.
Even though in the "Network port configurations" it is setup to use the "Built-in Ethernet" first, if it can't find that then use Airport...
When you place the ethernet port first it really means "use this port first and use the others too whenever they are available".

WRT120N Wireless Connection Problems

I'm having trouble connecting to my router all the time. When I first set up this router my laptop could see the SSID just fine. I clicked Connect, entered password, etc. computer said I was connected, but I could not access the internet. I am using DHCP and was even assigned an ip and everything. In order to finally get things working I have to manually click disconnect then reconnect once or twice and then it works. When I shut my computer down and turn it back on I have the same troubles connecting, as if my computer or router doesn't remember something. I am experiencing this on a XP machine and Vista machine, so I know it's not OS related. I have also upgraded the router to the most current firmware and am running WPA personal for security. What can I do? Is there some setting I am missing?

Since you have already upgraded the firmware on your Router, you need to reset your Router and Re-configure all the settings on your Router. Follow this settings for your Wireless and check if this solves your Problem .
Open an Internet Explorer browser page on your wired computer(desktop).In the address bar type - 192.168.1.1 and press Enter...Leave Username blank & in Password use admin in lower case...
For Wireless Settings, please do the following : -
Click on the Wireless tab
- Here select manual configuration...Wireless Network mode should be mixed...
- Provide a unique name in the Wireless Network Name (SSID) box in order to differentiate your network from your neighbours network...
- Set the Radio Band to Standard-20MHz and change the Standard channel to 11-2.462GHz...Wireless SSID broadcast should be Enabled and then click on Save Settings...
Please make a note of Wireless Network Name (SSID) as this is the Network Identifier...
For Wireless Security : -
Click on the Sub tab under Wireless > Wireless Security...
Change the Wireless security mode to WPA, For Encryption, select TKIP...For Passphrase input your desired WPA Key. For example , MySecretKey , This will serve as your network key whenever you connect to your wireless network. Do NOT give this key to anyone and remember the key.
NOTE : Passphrase should be more that 8 characters...
Now see if you can locate your Wireless Network and attempt to connect...
Click on Advanced Wireless Settings
Change the Beacon Interval to 75 >>Change the Fragmentation Threshold to 2304, Change the RTS Threshold to 2304 >>Click on "Save Settings"...
Now see if you can locate your Wireless Network and attempt to connect...

WRT54GL Security problem

First of all, I have two of the same routers. One totally works, and the other one partly works. The one that works, will hookup with or without security. The one I am having problems with, will work ONLY without security. Without security, it hooks up ar 54, and connects to the Internet just fine.
This router has to work with a Vista laptop, and a windows 7 laptop. I work on computers, and the one that does not work
belongs to a customer. Any ideas?

What type of wireless security did you use? WPA? WPA2?
Have you tried all wireless security types and none of them worked? Could be a router firmware issue. You may have to upgrade/reload the firmware.

HT1695 changed broadband providers when I type in Wireless Security Key (WPA) on my Ipod it comes up as Incorrect password and I cannot log in

I have changed broadband providers - when I type in their Wireless Security Key (WPA) into my Ipod it comes up - INCORRECT PASSWORD - I know it is case sensitive I am putting in numbers and capitals but does not work. Is there another Password I should be using ???

I have recently upgraded to Mountain Lion thinking that it might solve the problem but it hasn't worked.
It's possible your current os has different keychain troubleshooting solutions. Try re-posting (copy paste) over in the OS X Mountain Lion forum area and do a Knowledge Base search.
Have you tried setting up a new account to see if your issue appears there? If you have Apple Care, give them a call or take your computer to the nearest Apple Store or an AASP as you are still under warranty.
