Can no longer secure wifi network

I have a Linksys WRT54G router with the latest software upgrades and WMP54G adaptor with WPA security. Up until now these have been working together, and with 2 laptops and a Palm Tx. Suddenly last night, the network could not be detected although neighbours' networks could. On checking the router settings via a network cable, everything was set as normal, no changes had been made. When the SSID was enabled the network could be seen but the adaptors alternated between "acquiring..." and "connected" without a continuous connection.
I reinstalled the WMP54G and drivers, but no luck. Tried changing channels and all the tricks from previous posts, again without success. I then setup the network from scratch again and finally managed to get a connection, firstly with the default settings and then with more specific ones.
This evening it was back to square one. No connection. This time I reset the router to the factory defaults. Using these I could get a connection. Creating a new network identity also worked but as soon as any security was enabled the hunting between acquiring and connecting started once more. All ths was with a laptop no more than 2m from the router.
Has the radio finally died in the router? And if so, and I need a new one, why should I replace it with another Linksys model?
Thanks for your help.

Try to upgrade/refresh the firmware of the linksys router...This might resolve your issue.
Download the firmware from www.linksys.com/download and save it on the dekstop...Go to linksys setup page by typing 192.168.1.1 in the address bar..The default password would be admin...On the Linksys setup page under Administration tab..Click on firmware upgrade to upgrade the router's firmware. Once you upgrade the router successfully..Press and hold the reset button for 60 seconds..Release the button and take the power cable out from the router.After 30 seconds put the power cable back to router and reconfigure your router.

Can't connect to any secure WiFi network. Help...!

Hello,
I am unable to connect to any secure wifi network. Using iPhone 5, Model : MD300B/A, Software : 6.1.4 (10B350). Whenever I try to connect to any secure wifi network, it says password incorrect. But it connects fine with unsecured networks. Double checked the same secure networks with my iPad and it works fine. Tried reseting the network settings and all settings. Updated to latest firmware (6.1.4). Still not working.
Please help.
Regards,
Madhavan

I have the same problem. I can't connect to any password protected networks. I type in the correct password, but I'm unable to login. I don't have the option for the iphone to forget the network, because I've never been able to log in and therefore there is nothing to forget. The option doesn't even come up. Is anyone else having this problem? It is this way for 2 different networks.

3. Microsoft router MN-500:
Tried this old router (the one I used before purchasing the LinkSys). It is an old (circa 2002) Wireless B base station with WEP Security. The iPhone was never able to connect to the Internet using various settings, many of which were duplicates of the LinkSys tests above.
On both routers my wife's Dell laptop and my HP printer connect without incident, using the same network/security settings.
I have always been able to connect to various unsecured WiFi networks; I have never been able to connect to a secure WiFi network (although the only one I've really tried has been my own).
I am at a loss as to what to do next. Any suggestions?

SUCCESS!!!!!
I visited my brother-in-law yesterday and attempted to connect with his secure network. By sheer luck, he is using the exact same model LinkSys router. My iPhone connected first time--so the iPhone was eliminated as a source of the problem.
I didn't do a lot of troubleshooting at his house, but I did notice that his network was set for both dynamic DHCP and dynamic DNS. I know that either or both of Windstream (my ISP) and my broadband modem requires a pair of static DNS addresses.
Sure enough, delving real deep into Windstream's support site, I discovered a LinkSys router DNS help page, specifying how to set static DNS addresses in LinkSys routers. I then accessed my router, enterd the known static addresses, saved the router settings, then rebooted the iPhone and connected to the network.
SUCCESS!!!
Thanks to Jane, who suggested it was an ISP issue, Jason, and all at Apple support. dumonj, I'll email you directly. Try this suggestion and see if it helps.

I want to enter the password for a secure WIFI network on several iphones. If I do this, can the end users somehow extract the ip address and password for the wifi network from the iphone and use it from a pc (at home, for example)?

I want to enter the password for a secured wifi network on several iphones. If I do this, is it possible for the end users to somehow extract the ip address and password information and use it from a pc/laptop/other mobile device. For security reasons, I don't want them to be able to to this.
Please advise,
Thanks.

If you look at the top left of your screen you will either see a 3G (or 4G if you have AT&T) or you will see the wi-fi symbol. If you don't see the wi-fi symbol you are connecting to Gmail through your cellular data plan, not via wi-fi.
To answer your question, it doesn't happen often but when it does the steps I mentioned above will normally resolve it. Hopefully you won't have any further problem with this.

Can't see home wifi network

Today, I found that I could no longer see or sign on my home wifi network. Just my network; I can see my neighbors' wifi networks just fine (and connect on the unlocked ones).
I tried resetting the router and unplugging/replugging it multiple times, and also setting it up again via a pc. It is a secured network with a WEP password.
Weird thing is, my roommate who has a pc is having no problem seeing and getting on the network.
Did I mess up some network settings on my mac? I just switched to a mac about a year ago, so I'm pretty new at navigating through the settings.

Glad you got it working again, though I don't understand why resetting via the Mac worked when doing it via the PC hadn't. Another thing to add to the long list of things I don't understand I was sitting at my Mac trying to work out a list of debugging steps for you when your post came in, so I am delighted you let us know.

TS1398 I can not find my wifi network on my ipad. My iphone conected fine.

I can not find my wifi network on my ipad, My iphone connects fine. I tryed restarting the ipad and router. Please help

Some things to try first:
1. Turn Off your iPad. Then turn Off (disconnect power cord for 30 seconds or longer) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
2. Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
3. Change the channel on your wireless router (Auto or Channel 6 is best). Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
4. Go into your router security settings and change from WEP to WPA with AES.
5. Renew IP Address: (especially if you are droping internet connection)
    •    Launch Settings app
    •    Tap on Wi-Fi
    •    Tap on the blue arrow of the Wi-Fi network that you connect to from the list
    •    In the window that opens, tap on the Renew Lease button

Iphone connects to secured wifi network but cant surf the internet

I am trying to connect to the wifi at the office, it's a 64 bit WEP secured network (I enter a 10 character hex key). The Iphone connects to the network and is assigned a valid IP address. But when I try www.google.com or 64.233.167.99 for example, it fails with 'Safari could not open the page because the server stopped responding'.
It all works fine at home on my non secured wifi network.
Please, can someone help? Thanks.

Are you 100% sure the WiFi at your work has access to get out...and also, I assume they know you are getting on it. Not sure what type of office you are at (eg: large business with network support/admin or at a small office where you or somebody right there set it up).
But if large office with network admin...could be they locked it down with MacAddresses as well.

How can i delete a wifi network?

Thank you but I tried that and it still shows up as a network. I live out in the country and shouldn't have any other networks close. I am afraid of a security breach.
As far as networks showing up when you right click the WiFi icon in the Menu Bar, you will always see those that are close by. I know of no way to hide or remove those.
What leroydouglas provided is correct to remove any WiFi networks you have previously connected to.

I see another unsecured wifi network on my list. As I have recently changed routers etc. I just want to make sure it's not attached to me. It has a different IP address than the secured wifi network I have now set up.

I see another unsecured wifi network (D Link) on my list. As I have recently replaced an old modem router (D link) with a new fancy one (wireless gateway), I am wondering if this is somehow still attached to my computer. The D link wifi unsecured network has a different IP address than my newly formed secure wifi network's IP address.
Also - if I turn my wifi off (regardless of if I am on the dlink or my new secured wifi) I can still watch netflix etc. on my tv from living room which tells me the the wifi is still on. Why is this so?
Does my Mac have two IP addresses or is that D link someone elses?
THank you to anyone who can straighten me out on this as I am confused.

Thanks Tony,
Believe it or not, I had already done that - that is why I was confused as I kept seeing it in the wireless networks that I was seeing even though I had deleted it in my advanced Network of Systems Preferences. I thought if it were mine it would go away, but alas it didn't. Anyway, all is well and I can now relax that everything is secure thanks all to you.
Cheers

After I connect with my iPhone (3GS 5.0.1) to any Ad-hoc wireless Network then walk away out of the reach of my wifi network, my iPhone can't find any wifi Network afterwards, only by turning off the iPhone completely and turning on again.

switching off wifi and on again or going into airplane mode did't help!
This problem happens only with ad-hoc wifi networks not with normal ones.
(Ad-Hoc network was created on XP Computer)

Welcome to Apple Discussions
Sorry, but the 169.x.x.x IP address is internally generated by the iPod (and iPhone) and indicates that a network has been detected but no IP address has been issued. Your friends iPhone was not connected to your ad hoc network either - it connected to the internet through the 3G network.
You should read through the Vista help screens on ad hoc networking for some insight how this works. You should be able to get some ideas there.
In the mean time, $40 or less will buy you a very capable wireless router with four Ethernet ports and will simplify your network tremendously. Having used Windows ICS for a long time, the addition of a router and a real network simplified things so much.

My iphone can't see any wifi networks

my iphone can't see any wifi networks ... i tried to reset network setting and reset all setting and update the ios system but no way

I, too, fear it might be a hardware problem . I removed all security from my router but still no networks appear in the list nor can I connect directly by typing in the SSID. Tried two routers: Apple Airport Extreme and a Linksys something-er-other provided by Bell.
I will give HP a call tomorrow and see if they can sort this out.
Thank you for your help/advice!
Edit: almost certain it's a hardware problem: I clicked on the Help button while on that "Scanning for networks" dialog during initial setup and as one of the "helpful" suggestions, it said my Mac address was 00:00:00:etc.

Can't connect to wifi network after iOS update

Can't connect to wifi network after iOS update.

This does not work in my case.
Situation: we have wifi at home using WPA encryption.
The iPod Touch 8GB connected seamless to this network and anything was ok. After some days i could no longer connect, the iPod told me "connection to network 'networkname here' failed". Deleting the network and reenter the (correct) passphrase was no help, but changing the SSID on the router was helpful: the iPod could connect again ... for several days.
Now things stopped working again. Resetting network settings did not help either.
The iPod can see the network, is asking me for the passphrase and after several seconds telling me: can't connect. On the router log i don't even see a dhcp request, but other laptops work fine with the same wifi network.
That's a mess, i cannot and will not change the SSID every some days just to get the iPod working again.

I changed the channel on my Belkin Wireless router now my ipod touch 1G can't find my wifi network?

A few hours ago I changed the channel on my Belkin Wireless router for the 1st time. It was either on auto, or channel 6 before, i'm not sure, but I changed it to 11, and now my ipod touch 1G can't find my wifi network. I tried changing it to 6, but nothing, and I also can't go back to auto. Can someone please help. I've already searched for the network, and it says "Cant find network". I've also restarted my router. I also added the MAC address, still nothing. Other than those things, I havent touched anything else. My ipod could connect before just find. My Wifi is not disabled, and it's not on private. I can connect with other wifi's fine. And I can connect to other networks with my ipod, I also held down the button on top, and the home button for 10 seconds to restart and nothing. I also reset my network settings. Please help!

Find the documentation for your router and look up "Reset to Factory Defaults." This process will put the router back to the way it was when you bought it.
