Keep losing my wireless and mac addresses wont hold
For some reason, i could not delete or add any mac addresses to the aebs, which i have been using for the past couple years, so i did a hard reset on the unit. Now i have not added any security yet and the aebs keeps dropping my wireless connections. Any ideas?
To perform a Factory Default Reset......
Pull the power plug from the back of the AirPort Extreme
Wait 2-3 minutes
Hold in the reset button and keep holding it for 10-12 seconds while you plug the power back in to the Extreme
Release the reset button after the 10-12 hold period and allow 25-30 seconds for the Extreme to come back up to a slow blinking amber light
Before you start to reconfigure the Extreme again, power down your modem for 5-10 minutes, then restart it.

I bought a new MacBook Pro several months ago. I keep losing my wireless connection (my wife, sitting several feet from me has no problem with her iPad2). I find the quickest fix ix to turn Airport off and back on. Very annoying. Suggestions please?
What kind of wireless router are you using? more importantly which protocol are you connecting with? Are you and wife connecting using the 2.4Ghz band? or do you have a dual band router that offers the 5GHZ band? Are you both connecting vie 802.11 a/b/g or n?
The best thing to do is to go into SYSTEM PREFERENCES and select NETWORK, then select AIRPORT and click on the ADVANCED button.
Under the AirPort tab you should delete all the preferred networks and only add back in your network with the proper security settings and passwords.
If you hold down the option key on your keyboard while clicking on the airport icon at the top on your macbook pro. you'll seesome data that will tell you what band and mode you're connecting at, as well as in an indication of signal strength (RSSI) if you write down and post back that information it'll tell us what's going on. -
Satelite C660 keeps losing its wireless connection
Hi
We have bought the above laptop for our son for christmas and it keeps losing its wireless connection, we also have a Satelite L450 which is running fine (not losing internet connection) we have been onto our broadband supplier they have told us that as the wireless connection on our other laptop is fine, it is something to do with the C660, one of the drivers needs an update, unfortuneately I have forgotten the driver name but it is something to do with the modem, Our son is desperate to use his laptop.
Can anyone help?Had the same problem but with a different Satellite model - the signal was fine on another laptop in the room - the problem was the power management option / power plan - the link below says it all but in short if it is on balanced the default option the default means that it tells the router to go into a power save mode that it might not support.

My ipad3 seems to have connection issues. It is wifi only but keeps losing the connection and is really slow in loading pages - a bit like dial-up speed! My iPhone 4s and daughters' ipad2 have no problems at all. Any ideas anyone?
Look at iOS Troubleshooting Wi-Fi networks and connections http://support.apple.com/kb/TS1398

iOS: Recommended settings for Wi-Fi routers and access points http://support.apple.com/kb/HT4199
Additional things to try.
Try this first. Turn Off your iPad. Then turn Off (disconnect power cord) the wireless router & then back On. Now boot your iPad. Hopefully it will see the WiFi.
Go to Settings>Wi-Fi and turn Off. Then while at Settings>Wi-Fi, turn back On and chose a Network.
Change the channel on your wireless router. Instructions at http://macintoshhowto.com/advanced/how-to-get-a-good-range-on-your-wireless-netw ork.html
Another thing to try - Go into your router security settings and change from WEP to WPA with AES.

My imac keeps losing ISP, INTERNET AND SERVER but still has WIFi
my iMac keeps losing ISP, INTERNET and SEVER but is still connected to the Wi-Fi and when I tern on the mac i have to connect it every time and it is on preferred net work its the Olney one then after I connect it works for about 20 min then stops and I got to network preferences and click on ASSIST ME - DIAGONSTICS and it shows ISP INTERNET AND SEVER ALL IN YELLOW.
Open System Preferences Network pane. In the sidebar, if you see things you do not use for networking, remove them (you can add them back later if they are ever needed). For example, if you don't use Bluetooth or FireWire for networking, remove them from the list of networking services. To do this, select the item on the list and click the minus sign at the bottom of the sidebar. You can leave Ethernet on the list.
NOTE: Bluetooth and FireWire networking is not related to their use for connecting devices.
Also, click on the gear icon at the bottom of the sidebar, and select Set Service Order. Make sure Wi-Fi (or AirPort for older Mac OS X) is at the top of the list.
Apply the change (and maybe restart your Mac as well). See if that makes any difference. -
IMac keeps losing ISP, internet and Server but still connected to wifi
My Imac keeps losing ISP, Internet, and Server but is still connected to the Wifi. To recnnect, I have to go into Netwrok Diagnostics - assist me. This is happening every twenty minutes or so (sometimes less). Can anyone help? I might add that we have recently moved house and never had this problem before.
Wifi problems seem to crop up a lot on here and unfortunately there doesn't seem to be a 'one fix' solution.
However, sometimes any one of the following can help although, unfortunately, not always. In no particular order:
Check wifi security - if it's WEP change it to WPA or WPA2 (preferably, as it's more secure)
Change the wifi channel on the router
Create a new Network Location: http://support.apple.com/kb/HT5289
Reboot the router
Also take a look at this link and the links within the article for other ideas. They mainly reference Lion, but still seem to be relevant to Mountain Lion:

The wlc permits choose radius Call station ip type MAC or IP, but not both.
Thanks you,If you are using dot1x then no, the mac address is sent since the client does not receive an ip address till authetication succeeds.

I keep losing my tabs and history and I have it set in FF to save my history. It doesn't happen all the time just randomly but still annoying. I read all the help and everything that they said to check was fine. I also don't get the icons on every tab like I used to. some have it some don't. I have a tab up for Yahoo and it used to show the Y and now just an empty box. but Facebook shows the F.
I can live without the tab icons but it is really annoying when I lose all my history and tabs.Firefox > Tools > Options > Privacy > History

MAC Authentication
Add a MAC Address to ACS
Complete these steps:
1. From the ACS main menu, click on the User Setup button.
2. In the User text box, enter the MAC address to add to the user database.
Note: The MAC address must be exactly as it is sent by the AP for both the username and the password. If authentication fails, check the failed attempts log to see how the MAC is being reported by the AP. Do not cut and paste the MAC address, as this can introduce phantom characters.
3. On the User Setup screen, enter the MAC address in the Secure-PAP password text box.
Note: The MAC address must be exactly as it is sent by the AP for both the username and the password. If authentication fails, check the failed attempts log to see how the MAC is being reported by the AP. Do not cut and paste the MAC address, as this can introduce phantom characters.
4. Check the Separate (CHAP/MS-CHAP) box.
5. Enter a password for CHAP/MS-CHAP (this password should be different from the MAC address).
6. Click Submit. -
How to set the IP and MAC address in C program?
My working environment is Sun250 Server, Solaris 7 operating system. I encountered a problem ---- How to set the IP and MAC address in C program to make the system change it IP & MAC at runtime?
Any idea is welcome! Thanks!Hi
As a simplest possible solution, you can use the system command
to run ifconfig that can set both the mac address and the IP address of the system. You will have to use setuid though.
Or you can use the DLPI calls ( do a man DLPI or search for a
Sun documentation on the same at http://soldc.sun.com) to write
a pure C program.

Client Identifier and MAC addresses
Hello Everyone,
I am migrating my DHCP services from an old SUN server to an OES Linux server. In the old SUN files, my client identifier and mac addresses have a leading pair. So if my mac address is 00:30:C1:57:44:09, it is entered in the SUN files like this: 01:00:30:C1:57:44:09. My question is, do I need to enter that extra pair in my host records for OES Linux DHCP? If I do or don't, does it matter?
The reason I'm asking is that many of my older printers and even some of the newer ones are not picking up an address from the new DHCP server when the old one expires.
Thanks,

Whilst I've seen this with NetWare-based DHCP the DHCP on OES Linux uses
different objects and is provided by ISC DHCP which does not have this -
my DHCP hosts are configured just with MAC address.
If you examine a dhcpHost object in ConsoleOne - clicking the Other tab
should show the dhcpHWAddress attribute has the value "ethernet
01:23:45:67:89:ab" (where 01:23:45:67:89:ab is MAC address).

Just printers or other types of devices too?
If printers, particularly HP ones, check that they're set to pick up IP
details via DHCP and not BOOTP. Yes should still work but we've seen
problems here.
