My roommates computers can't connect to the router!

Hey, so I've got this Cisco Lynksys E1200 and I've got internet going to it. When I first tried to connect to it my computor automaticaly set it up (giving the network a name, changing it from tehdefault "Cisco67809" to my perfered natwork name, etc.). The problem is that my rommates laptops cant seem to connect to it properly. I know their internet cards work because they have been able to access the internet via other nearby networks on occasion.
On the 2nd computor it skips the usual..."Conecting to network" attempt and instead just says it cant connect, but its so quick to say that it cant connect that it doesn't even seem to be trying, no request for password or anything! Yet we know the computor does try to connect to other networks, so why would it be so quick to deny a connection with our network without even telling us its "trying to connect"? It then gives the options to "diagnose the problem" or "connect to another network" but the diagnose function just says it can't do anything and gives no information about whats going on.
With the 3rd computor it does connect, or so it says "conected" but with "Limited Acess" and absolutly no accesss to actual internet content.
I have tried to fully reset the router multiple times, creating brand new networks, but the same issue continues to happen. I thought it might have decided my computor was the only one allowed to access it because on each reset I was using my computor to set up the network, but when I reset it and tried to have my roomate on computor #2 set up the router and network (aka change it fromdefault Cisco67809 to our own in house network) it did not allow him to set up the network from scratch as I had done twice.
Why is this router rejecting computors and what can be done to get them online? When I log in to the routers settings it says it is set to allow up to 50 users. So far we have my laptop, and Ipad, and an I touch conneted successfully. Why cant we get the two other laptops on it?

Hi,
Can you try to clear or remove the Wireless Network Profile from those computers that can't connect? Then, try to reconnect afterwards. Probably, those old profiles stored on other computer have different wireless settings. On the E1200, make sure that MAC address filtering and Parental Control are disabled. Access your router's setup page then go to Wireless > Wireless MAC Filter > then check if it's Disabled. For Parental Control, you can access it via Access Policy tab.
Hope this helps.
If everyone needs to believe in something, I believe I'll have another beer..

I can't connect to the router in my home. Things were working fine as usual - I attended school and connected to their WiFi network as usual. When I returned home I could not connect to my own home router. The Ipad seeks the network but nothing happens

I can't connect to the router in my home. The Ipad seeks the network but nothing happens. I went to school and connected to their WiFi network as usual with no problems. When I returned home I could not connect to my home router. The Ipad seeks the router number but nothing happens. I rebooted the Ipad a few times in the school. The numbers identifying the router, etc. on my Ipad no longer appear there.
TThe Ipad guide says to connect to the WiFi use setup but I can't find the setup program in the Ipad.
I reset the network settings to the factory defaults but this doesn't fix the problem.
What can I do to reconnect to my home router?

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

After software Update (2006-07), airport can not connect to the router

Hi,
I installed the software update 2006-07. Afterwards the airport extreme can not connect to the router anymore (NETGEAR). I use a WEP key, but even if I type the WEP Key, the airport does not succeed to the router anymore... I called Apple Care and they wanted that I install the firmware restoration. But even I didn't succeed to install the firmware restoration. On the firmware restoration web page (http://www.apple.com/support/downloads/firmwarerestorationcd12.html) is written that I have to turn on the computer and continue holding down the power button until the LED blinks rapidly followed immediately by a successive series of blinks (3 quick blinks, 3 slow blinks, 3 quick blinks). But after the LED blinks, there is not the successive series of blinks...
I know there is 2 questions in one message, but could you please help?
Thanks in advance.
Best regards,
Eric

my mac is accessing the internet fine, but my laptop (windows) can't log on to my wireless network and connect to the internet.
i've tried to change my internet sharing preferences under "sharing", "internet", but that does not seem to be the right solution. when i try to connect with my laptop, it asks me to enter in a WEP, ASCII code. i've read all through the help menu and it told me to enter in "applecomputer" as the password, but that doesn't work either.

I can not connect to my server via the VPN client i have attached the config. I also havve a bif problem i can't use the webb gui any more and idon't know why.
Thanks i advance

You would need to change the NAT from standard ACL to extended ACL as follows:
access-list 150 deny ip 192.168.1.0 0.0.0.255 192.168.0.0 0.0.0.255
access-list 150 permit ip 192.168.1.0 0.0.0.255 any
ip nat inside source list 150 interface ATM0.1 overload
no ip nat inside source list 1 interface ATM0.1 overload

Moved my laptop and now I can't connect to the router

I'm a novice at this - but that didn't stop me from setting up a wireless network - it was very easy, everything went fine and was working great for months. I took the laptop out of the house and used it at another location. When I brought the laptop home again it asked for a password - which do I use the passphrase or Key 1? Should I expect this to happen everytime I mobilize the laptop? My router is WRT54G. Thanks!

Connect to your router with a cable and name your network different. "linksys" is the default network name of a Linksys wireless router. Anyone you buys a Linksys router and just plugs it without changing it ends up with it. Maybe another neighbor bought a Linksys router as well. Thus, always rename the network name to something unique so that you can be sure that you connect to your network and not to somebody else's. Because the problem is: when your computer searches for wireless networks it only checks the name of the network. It does not show whether there is only one access point with that name or several. It could be a roaming network where several access points must have the same name or it could be just accident like several people running routers with the default name. Therefore: connect to your router with a cable, open http://192.168.1.1/ and reconfigure the wireless network name (SSID) on the wireless tab to something else. Connect to that network...

WRT120N works only on Vista computers - all XP computers can't connect

Could someone help me solve this problem please? I'm this close to smashing my Linksys router against the wall and swearing off Linksys for the rest of my life.
I bought the WRT120N wireless router for use with a Motorola cable modem. On WPA, NONE of my computers can even connect to the router. So I tried using WEP and my primary computer which runs on Vista works, but only when network mode is either G-only / B-only / BG-Mixed But three other work and personal laptops that are on XP are unable to connect to the network no matter what settings I change. I have tried disabling security, but the XP laptops can't connect to these networks as well. There isn't an error message or anything, it shows that it's connecting, and then disappears after 5 to 10 minutes, but the wireless icon shows its not connected. It may not be a Vista/ XP issue, but three laptops convinced me that it has to be more than a coincidence.
Network Mode: BG-Mixed
Network Name (SSID):
Channel Width: 20Mhz only
Wide Channel:: Auto
Standard Channel: Auto
SSID Broadcast:
Enabled
Under Wireless Security, the settings are
AP Isolation Disabled
Frame Burst Enabled
Authentication Type, Basic Rate, Transmission Rate, N Transmission Rate, CTS Protection Mode are all set to Auto
Appreciate any help that anyone can give. But appreciate if you could be specific as I'm not well-versed in all things IT.
Thanks in advance!

Befor you make any further changes on your Router, the First thing which you need to do is to Upgrade the firmware on your Router. Download the latest firmware for your Router from the Linksys Router and upgrade that firmware on your Router...
Once the firmware is upgraded successfully on your Router, then you need to Press and hold the reset button for 30 seconds...Release the reset button...Unplug the power cable from your router, wait for 30 seconds and re-connect the power cable...Now re-configure your router...

Can't Connect To The Internet Or Router

I have had my router set up for about three years. It's always worked perfectly fine until the other day. I think that the router just died, but I'm not sure and I want to try and fix this one before I just go out and buy a new one.
Basic Background Information:
Model No:WRT54GC
-The router is and always has been hooked up to a surge protector and there haven't been any other recent surges in my home.
-When the wireless router is connected to the computer (using a functioning Ethernet cable ) I cannot connect to the internet or the router. (I can't even put the IP into a browser and bring it up. I also tried the factory setting IP, just incase it actually did reset, and that doesn't work either.)
-When the router is plugged in I can't see it from any other wireless computer. (I also checked for any new signals and did not see any after I reset the router.)
-LEDs look like:
*Power = solid green
*Internet = solid green
*wireless = hard to tell - doesn't look like it's on at all
*all other Ethernet pluggins = solid green
What I've Tried So Far:
-I couldn't connect to the internet so I plugged the modem directly into my computer. --> The internet works.
-I tried unplugging the router, waiting, and then plugging it back in. --> I couldn't connect to the internet or the router.
-I tried the reset button. --> I couldn't connect to the internet or the router.
-I tried leaving the router unplugged all night and then plugging it in and starting the process all over again. --> I couldn't connect to the internet or the router.
-I also tried downloading new firmware, but since I can't connect to the router through any of my browsers I am unsure how else to update the firmware.
Thanks in advance for any help!

Try upgrading your Router's firmware and then you can reconfigure your Router from the scratch...
As you are not able to go online through router...you have to download the formware by connecting computer to the modem..
Go to website linksysbycisco.com/downloads.........insert model no of your router in serach tab......select proper version of your router........download the firmware file......save that file on desktop
Now reconnect the Modem to Router on Internet Port and from Computer to Router on Ethernet Port 1and now Press and hold the reset button for 60 seconds...Release the reset button...Unplug the power cable from your router, wait for 30 seconds and re-connect the power cable...
Now you can upgrade the firmware using TFTP utility...Download tftp utility.
Follow these steps to upgrade the firmware on the device : -
Double click the TFTP.exe file and click run.
For Server- Enter the IP Address of the router that you assigned. By default, the router is 192.168.1.1...
For Password- Enter the password you assigned the router. By default, the router’s password is “admin”.
For File- Click the triple “…” button and browse for the .bin firmware file...
Click Upgrade button to start upgrading. A progress bar should show up to show the progress.
Once the Upgrade is done press and hold the reset button for 30 seconds...Release the reset button...Unplug the power cable from your router, wait for 30 seconds and re-connect the power cable...Now re-configure your router...

Can connect to my house network, but can't connect to the Internet (other computers can)

Hello,
I'm experiencing a strange problem. Since I started my Mac Pro (cold start) some hours ago, I've lost the hability to connect to the Internet (Safari and Mail say I'm not connected). However, I can connect to 192.168.2.1 (my router) and see its webpage (it says it's connected to the Internet). If I use another computer on the same network, it can also connect to the Internet.
Weirder, if I go back to my Mac Pro with "no internet" and launch Parallels Desktop, then I can use WinXP to browse the Internet; I'm writing this post on my WinXP virtual machine.
This leads me to think there's a problem with how my Mac OS handles the networking. I have checked the Console, but the only related string I found is this:
16.04.13 22:03:25
kernel
SIOCPROTOATTACH_IN6: en2 error=17
As expected, Google doesn't reveal anything about that (and I'm connected with the first ethernet port). I've tried to restart my Mac, but the problem persists (exact same symptoms).
Could it be a DNS cache issue?
I don't see, other than a DNS problem, why I can't connect to the Internet with my Mac OS while I can on my virtual machines. If it was a driver problem, I wouldn't be able to connect to my router. If it's a DNS issue, where are the DNS caches located in order to clear them (I'd trash the folder)?
I could also reinstall the OS (waste of time, btw), but I'd really like to understand the problem, not just clear it and forget about it.
Or better than guesses, anyone already experienced this?
Any help welcome.

If it's a DNS issue, where are the DNS caches located in order to clear them (I'd trash the folder)
No DNS caches, it looks up the alphabetic and then uses the numberic from then on.
http://17.149.160.49
is Apple, Inc main US web site. It that works, and the alphabetic does not, you have a DNS probelm.

I can't connect with the Time Capsule.

Hello everyone,
Some years ago, I bought a Time Capsule. Until now, I didn't want to use it as an extern HD.
So I tried today.
I am using it for a year now, as main router. Several computers and iDevices are using it.
Because I had forgotten some things - and I hadn't wrote it down - I decided to reset it and configure it again.
Since then, the internet has become slower - and I my Macbook pro can't connect to the Time Capsule's disk.
In Finder's everything fine. Left, under 'Shared', I can see the Time Capsule as a HD.
When I click on it, I see: "No Connection". Then I select "Connect As", and I fill in the Time Capsule password.
It tries to connect a few minutes, but then I get the message:
"The backup disk could not be found. Make sure the backup disk is connected or open Time Machine preferences to select a different backup disk."
In the Airport Utility, there's a green light.
*My firmware has the newest updates
*I am using Snow Leopard
*I am using newest update of the Airport Utility
*Since reset, internet's fine but a bit slower.
Other Questions:
*Can I use my Time Capsule for other things than only Time Machine (backup)?
*Can I divide it in parts? (Backup, User)
*Can I backup multiple devices on it? (Macbook Pro, iMac, Macbook Air etc.)
Hope you can help me!

What actual model is the TC.. the A1xxx number from the rubber base mat???
As they age they become unreliable. Some earlier and some at 3year mark.
It greatly depends on the setup of the existing network.
I would recommend a downgrade in the TC firmware.. as with Snow Leopard there is no advantage to you in the later firmware.
Go to the airport utility and select firmware update.. hold down the option key when you make the selection and all the previous versions available for your model will come up. I recommend using 7.5.2
Do another reset of the device. This time a full factory reset.. and start the configuration again.
Ignore update to firmware requests.. turn off the reminder.
Set all names to SMB standard. short, no spaces, pure alphanumeric. TC name, wireless names, hard disk name.
For wireless I recommend you use wpa2 security with 8-12 character passkey.. pure alphanumeric.
Set to manual for radio channels and test 1, 6, 11 in turn for the best.
Depending on the broadband you use, the TC must be in router or bridge mode.. tell us more if you need help for this.
If you think the TC is slowing you down, do a test with direct connection to the broadband modem and give us the speed comparison.. direct and via the TC ethernet or wireless.. tell us which though.. wireless will always be slower than ethernet.
If you have issues still with the hard disk it might need some work.. older models the disk might need to be erased .. please open any time machine backup and run a verify.

http://pondini.org/TM/Troubleshooting.html
Other Questions:
*Can I use my Time Capsule for other things than only Time Machine (backup)?
Yes, but the TC is designed primarily for Time Machine.. if you store files, there is no method in the TC to back up those files.. do not make them the only store.
*Can I divide it in parts? (Backup, User)
You cannot partition a TC .. not without removing the disk. You can create a disk image.
Q3 http://pondini.org/TM/Time_Capsule.html
*Can I backup multiple devices on it? (Macbook Pro, iMac, Macbook Air etc.)
You can use multiple devices with TM. Be aware you need lots of free space for this to be successful. So you need to add up the total you want to backup on each computer.. and at least double it.

Can't connect to the internet with airport or firewire

I can't seem to connect to the internet with airport or firewire. I recently restored my old G4 mac mini PPC 1.42 (with airport and bluetooth) Tiger 10.4.8 with a new harddrive. I have it connected to my leopard mac pro, internet sharing is on (both computers), the systems are connected, however, the mini just can't connect to the internet. tried it also using airport, no go. network diagnosis seems to go in a constant loop.

works ok with ethernet connection though.
that'll work.

Updating firmware when I can't get an internet connection through the router

I am trying to update the firmware for WRT54G V8, but some of the instructions indicate I need to have the router connected and be connected to the internet. I cannot get an internet connection through the router. Can I upgrade firmware without being connected to the internet through the router. (I have had this router for about a year and a half with no problems until now.)

Yes, you can upgrade the firmware without an Internet connection.
To upgrade the firmware, first download the new firmware into a computer that you can wire to your router.
Next, power down your entire network.
Then wire the computer to a LAN port on the router.
Disconnect all other wires from the router.
Power up the router and allow it to fully boot (1-2 minutes).
Power up your computer.
Login to the router, and do the firmware upgrade (it will likely take several minutes).
Power down your entire network.
Next you need to reset the router to factory defaults.
To reset your router to factory defaults, use the following procedure:
1) Power down all computers, the router, and the modem, and unplug them from the wall.
2) Disconnect all wires from the router.
3) Power up the router and allow it to fully boot (1-2 minutes).
4) Press and hold the reset button for 30 seconds, then release it, then let the router reset and reboot (2-3 minutes).
5) Power down the router.
6) Connect one computer by wire to port 1 on the router (NOT to the internet port).
7) Power up the router and allow it to fully boot (1-2 minutes).
8) Power up the computer (if the computer has a wireless card, make sure it is off).
9) Try to ping the router. To do this, click the "Start" button > All Programs > Accessories > Command Prompt. A black DOS box will appear. Enter the following: "ping 192.168.1.1" (no quotes), and hit the Enter key. You will see 3 or 4 lines that start either with "Reply from ... " or "Request timed out." If you see "Reply from ...", your computer has found your router.
10) Open your browser and point it to 192.168.1.1. This will take you to your router's login page. Leave the user name blank, and in the password field, enter "admin" (with no quotes). This will take you to your router setup page. Note the version number of your firmware (usually listed near upper right corner of screen). Exit your browser.
If you get this far without problems, try the setup disk (or setup the router manually, if you prefer), and see if you can get your router setup and working.
If you cannot get "Reply from ..." in step 9 above, your router is likely dead. Report back with this problem
If you get a reply in step 9, but cannot complete step 10, then either your router is dead or the firmware is corrupt. Report back with this problem.
If you need additional help, please state your ISP, the make and model of your modem, your router's firmware version, and the results of steps 9 and 10. Also, if you get any error messages, copy them exactly and report back.
Please let me know how things turn out for you.

Problem with Safari **Safari can't connect to the server**

My internet is working fine, but I keep having to refresh the page because I'm always getting "safari can't connect to the server". Same thing happens with different browsers. I've read a couple things online and unistalled everything that I think is causing the problem but it's still happening frequently. Any help would be greatly appreciated!

Most school networks are closed networks. You can access their Intranet, with all the files and peripherals and everything, but you need to have a specific password or IP address to access any outside connection. I have an ibook G4 that's 3 years old. I used it in high-school to access AOL wirelessly. That was before closed and protected networks were prefered. It shouldn't matter if the school intranet is widows based or not. You need to access your own internet service sometimes in order to get any reaction. If you simply use safari, you might only be connecting to the schools intranet, which only links together the schools computers and keeps the system isolated. Also, you need to check your firewall settings, in fact, just turn off the firewall. The schools sytem is firewalled up the bum and you shouldn't get attacks anyway because you're running the mac os.
You might also try an alternative approach. Go into a computer lab, access one of the systems, then go to control panels and look up every connection you can find. Take down all of the info and then see which matches up with similar info on your mac. Then go to another pc and look up the same info again. Is it different? How? Then take that listing to the system administrator and show them. They may not know that a mac has a simpler interface than the pc, so you may have to do some prodding to get them to take a look. If they still tell you it wont work, you could try boot-camp or a virtualizer (to let you run windows alongside the mac os). If you use a virtualizer, you can get your own copy of windows and then share it's connection to the main system to the mac.

IMac can't connect to the network.

When I try to open safari (version 5.1.1) I get the message "Safari can't connect to the server."
iTunes can't connect either.
However when I go under system preferences> network, it says Wi-Fi is connected. And all the other computers in the house can get online fine.
I use this computer pretty much just for video/film work, and very rarely use it to go online, so this problem could've been going on for several months without me noticing. (At the moment I need to download some software.)
I've googled it, and seen other people with similar problems, but so far none of their solutions have worked,
Thanks in advance for any help!

In the networks pane of system preferences, click on assist me, and choose diagnostics. Follow the instructions to diagnose the problem network. This may provide useful information to continue troubleshooting.

I just returned from vacation in the states and I can't connect to the internet

i can't connect to the internet on my mac air. I know that the internet connection is good because other devices and computers are using it. I'm not sure if it is because I used my computer in the states while I was on computer. Can you help me get back on?

Run the Network Diagnostics assistant. How far do you get?

My roommates computers can't connect to the router!
