MacMini - Wired connection works, wireless doesn't

I've got a perplexing problem here. From the time I got my Mac Mini (about 10 months ago, upgraded to Lion a week or two ago) up until this morning, the wifi connection has worked fine. Mysteriously, this morning after I finished some reports for work, it quit working. My Windows netbook connects to the same wireless router and works fine, as does my phone. The wifi indicator at the upper-right indicates that it is connected to my router. If I go into Network Preferences/Advanced and click on TCP/IP it has a valid IP address for my network. If I go into terminal I can ping the router and I can ping websites by domain name so it appears to be resolving addresses properly. I can ping other computers on the network. I didn't install any updates or anything prior to it stopping working. I was in google apps for a couple hours and it was working fine, I ran my kids to school and then when I got home this issue started. If I go into any app that makes use of the internet connection (web browsers, iTunes, etc.) they all time out and are unable to connect. I have restarted many times. Full shut down and let it sit for a couple hours. Turned off the wireless and turned it back on. Specified a manual IP address, returned it to DHCP...all the same behavior. If I connect an ethernet cable (also connected to the same router) everything magically starts working. Any ideas? Thanks.

1. On your desktop, click Start. Type cmd in the Start Search box, and then press ENTER
At the command prompt, type the following command, and then press ENTER:
ipconfig
or try this http://www6.nohold.net/Cisco2/ukp.aspx?vw=1&docid=ebe56f15763e4c27b44816c831d68f95_3997.xml&pid=96&s...
Look for IP address.
2. To check the your Internet IP address, on the router's page look for status tab. Paste here whatever information you have there. It will look like this, click here. Which shows 192.168.1.3.
I hope that clears it. :-)

WRT54G wired connection works wireless doesn't

I am having the exact same problem. When I plug my computer directly into the modem I can access the internet, but there is no connection when I plug my computer into the router and the router into the modem. Even when I have changed the IP address on the Setup page, the Status page still says 0.0.0.0. I have done all of the steps that you have instructed here. I also have AT&T DSL service.

Go here to connect via DSL service.

Actiontec MI424WR dropping wireless connection intermittently; wired connection works

I've had this router for about two years, with no issues.
Beginning on Saturday, our two laptops and phones began losing their connection to our wireless network, dropping the signal every 30 seconds or so. I tested the wired connection by plugging the laptops directly into the router, and both computers functioned properly - no issues connecting or staying connected. I have my Roku hard-wired to the router, and that also has had no issue, so it'd definitely a problem with the wireless signal to my devices.
Spoke to a CS rep, who had me first check the internet signal (green, blinking sporadically, which I was told indicated no issue with the connection), then had me reset the router and unplug. No dice. She said the internet signal seemed fine, and that "everything looked good on her end", whatever that means. They're sending a new router which I'll receive today or tomorrow, but I have trepidation.
Has anyone else had this issue? I saw alot of router issues on the forums, but wasn't sure if everyone was having this specific problem (just wireless connect issues).
Solved!
Go to Solution.

This turns out to be good advice. I changed the channel on my router settings to 11 (per an earlier post on a different thread), and I haven't had an issue since. Here's the original post: "01-21-2011 11:32 AM that type of problem doesn't sound like a router issue, but instead sounds like a wireless transmission issue. you may be able to resolve that fairly easily.. Try to change the wireless signal. you can do that in the router. open a browser, and go to http://192.168.1.1, user name is admin. and the password is most likely the serial number found on the service tag of your VZ router unless you changed it. Once you login successfully, go to the top and hit wireless, then on the left basic security. then go to option 3 which is channel 1, 6 and 11 and are the only channels you should try. So it will likely be set to auto, change it to 11 and put the check for keep settings even after reboot (Directly under the channel) and then hit apply., after you hit apply, test your connection out, if you notice a difference, leave it like that until the problem happens again, and if it happens again, go back into the router, and try channel 6, test it out. and then finally 1 if the first two don't work."

Airpot extreme 4th gen, internet connection works and doesn't work

I have this airport extreme 4th generation that worked just perfectly untill 2 days ago.
I have a modem from the Tel Company. From there a RJ45 cable goes into the Airposrt extreme.
The light is green.
If I open the airport utility, it tells me the internet connection works (green light) and sometimes doesn't works (orange light)
I first had problem with wifi on iPhone 4s (wife and friends), who couldn't join the wifi network anymore. They can see the wifi network, they type the password but can't login.
I had problems with my last gen MacBookPro, apparently for no reason. Sometimes it connects some other time it doesn't.
Same story with my iPhone5.
I also made an hard reset of the airport extreme but with no result. nothing changed.
Sometimes the internet connection is on some other times is off.
Now I want to understand where is the problem, can be the ISP, can be the airport that is damaged?
Thanks.

Router mode: Bridge mode
You do not have multiple public IP.. DHCP is the wrong setting..
One or the other has to be bridged.. the AE is currently the one bridged..
Or the modem has to be bridged.. pick on or the other.
Did you chack the modem logs?
What modem is it?
What do the lights on the modem show when the connection drops out?
Did you plug something directly into the modem and see if internet is still working when the AE stops working??

Slow Internet on wired connection, fast wireless on same network

Hi,
My Internet connection has just been upgraded from 2MB/s to 10MB/s. To confirm the upgrade I have used www.speedtest.net with Firefox 3.5.1 to test my upload/download speeds. I have 2 computers on my network which consists of a cable modem connected to a white airport base station with 128 bit WEP encryption in 802.11 b/g compatible mode. The 2 computers are a dual 2.8 ghz MacPro which is wired directly into the Airport base station by Ethernet and an iMac 1.83 Intel core 2 duo which connects wirelessly. Both machines are running OS X 10.5.7. The much faster MacPro only achieves a download speed of 5.7MB/s over its wired connection while the slower iMac achieves 9.8MB/s - very close to the advertised speed over its wireless connection. Both upload at the same 512kb speed. These are consistent speeds not one offs so I am wondering why the difference? The MacPro is my main machine so I'd like to have the best speed possible on that.
I have tried connecting the MacPro directly to the Cable Modem, bypassing the airport base station and get the same speeds.
Any ideas? What else can I try?
Thanks for reading all that, I've put in as many details as possible, I'm really stumped!
Thanks in advance,
Alan.

First, be sure you're not confusing "MB/s" (megabytes/sec) and "Mb/s" (megabits/sec). These will normally differ by (roughly) a factor of 10. The value of "9.8MB/s" over 802.11g is presumably actually "9.8Mb/s", as the higher value exceeds the maximum rate for that protocol.
Second, what type of Ethernet cable ("CAT-x") are you using? An older cable can cut your maximum data rate.
What speed do you see with the iMac if you connect it via Ethernet?

Had to reset router, wired connection fine wireless not working even w/out security

hi, after that freakin blackout that made my internet stop workin, i did a complete reset to my router, and reconfigured it all over again, now i can connect to the internet if im wired to it but if im wireless i cant (tried with other laptops, xbox and it wouldnt work) i even left the wireless without security but its the same, when i click on connect to my network, it hangs forever "connecting" and in the end it remains unconnected... BTW i have a button in wireless settings "Status SES Inactive" which in the first firmware version it wasnt there, and i dont know what its for and if i should use it (what is "SES"? its not in the help manual)

hi..
hmmm.....i hope i cn help u im not so sure if it will work but then try to do so....
access the set-up page...try 192.168.1.1 or if it will not prompt for a username and a password just in case that u r n a dsl connection use this 192.168.2.1...launch internet explorer and type 192.168.2.1 on the address bar u shud be promted with a username and password
leave the usrname blank and passwrd is "admin" if ever admin password will not work try to type in any password tht u can possibly use and after that u must be able to access the router's set-up page....
on the router's set-up page
click on wireless tab
change the ssid or network name to ur preferred network name like ur name or ur lastname...
after that click save settings and it will tell u if saving the settings is succesful.....
after that click again on wireless tab and click the wireless security tab
and then change the security mode to WPA personal or if ever u can't see the WPA personal click on WPA pre-shared key and type on the wpa pre-shared key box the network key for ur router it is like a password for ur network.....type in at least 8 characters....
and click save settings.....
and then close that window and try on ur wireless computer to view avaliable network and then refresh network list and look for ur network name and hit connect there the comp will ask for a network key type in there ur network key....
take care...
i'm not sure if it cn help u but just try to do so...

BEFW11S4 v4 - wired devices work, wireless devices cannot connect to the Internet

Greetings,
I have a Linksys BEFW11S4 Wireless, ver 4. I have a PC connected directly to one of the Ethernet ports, and have no problem with that connection. I have a DSL service from Verizon. All devices are running Windows XP.
My wireless Laptop, as well as other desktop with wireless USB adapter cannot access the Internet. It seems that I have a wireless connection between the router and these devices since my Laptop can see the SSID and the wireless network and connect to it. But when I try to launch IE explorer or use AOL, I am not successful.
The frustrating part is that the wireless laptop used to work just few days ago and I haven't changed any set-up or added any hardware. I have tried to re-install the router, and also did few resets...but nothing is working.
Any help would be greatly appreciated.
Thank you,
Elie

Elie,
From one of the wireless computer, wither desktop or laptop, try this to help isolate the issue:
fo to Start>run> type "cmd" then click enter
that would open MS DOS, type: Ping (your router IP address)
For Example, if the router IP address is 192.168.1.1, then type:
ping 192.168.1.1 then click enter
if it does not come back with a time out, then you your PC is connected to the router. If it did time out, then it is the wireless connection.
If so, check the wireless configuration on the router, as of SSID, security if any , etc.. and make sure that the wireless card in each desktop and laptop match those settings. Be aware that SSID is "case sensitive" so it has to match exactly the one in the router.
hope that will help you in troubleshooting the issue

Wired works, Wireless doesn't

When I connect my computer with a wire router is works just fine and I have no problem getting online but when tried to setup a wireless route it won't let me go online. All the lights are on (power, WLAN, Ethernet channel and Internet). What am I doing wrong?
Solved!
Go to Solution.

Did you setup security on the router. Did you set a unique SSID. Has this ever worked before. What Operating System are you using. What model router do you have.

Wired Connection Works, but Wireless won't connect

I just got the Wireless-N Broadband Router and I have my Home computer connected to it through a LAN connection. And I have an internet connection. But on my Laptop the only thing that my WiFi connection picks up is HPsetup (Is this my Linksys Router?).. The Hpsetup has a very low connection by my Linksys Router. And the signal fades in and out.

what Conection protocol does your Laptop use?
PreN, 802.11g, 802.11b?

AEBS and TC - wired connection, same wireless network

I need some advice.
I have AEBS and TC. Currently, the connection between them is "Extend wireless network". They are located on the opposite ends of my condo. I am doing some work on my unit and I have a chance to draw an ethernet cable between them. However, I'd like both of them to be the same wireless network, so that I have good coverage in and around my unit and have good speeds for accessing NAS units on the network.
Which ports would I connect with the ethernet cable and how would I configure the wireless network?
Thank you!

Main unit has eithernet cable from LAN port that connects to WAN port of second unit.
Second unit is set up in bridge mode. You should not use "WDS" or "Extend Network" These are only for wirelessly extending the network.
The second base station should be set to a "DIFFERENT" wireless channel, however the network name and security settings should be identical to the main base station.
As long as the base stations have the same network name, roaming will work between them.
Again, they need to be set to different channels so that they don't interfere with each other.

Time Capsule: Wired connection works but cannot connect via wifi to net

Hi all,
I've had a Time Capsule for a year or so. I've been having problems with connectivity over recent months and I'm not sure where the issue is.
I have plugged in an ethernet cable joining my MBA to the TC, and another from the TC to the wall socket. I can access the internet without any problems.
However, if I unplug the ethernet cable from my MBA (or indeed if I don't plug it in in the first place) then I cannot connect to the internet. I can still back up to Time Machine etc., but nothing can get 'through' the TC.
Also, if I turn Mobile Data off for my iPhone, I cannot then access the internet via WiFi through the TC.
Any ideas as to how to fix this? The TC is in bridging mode, which has worked fine before. All suggestions welcome!

Ok.. let me try again..
Going back to your first post.
I have plugged in an ethernet cable joining my MBA to the TC, and another from the TC to the wall socket. I can access the internet without any problems.
However, if I unplug the ethernet cable from my MBA (or indeed if I don't plug it in in the first place) then I cannot connect to the internet. I can still back up to Time Machine etc., but nothing can get 'through' the TC.
When you plug in via ethernet the MBA works but not by wireless..
Now add that to the new info.
The campus network relies on each PC's individual MAC address and then assigns IP addresses as required;
Is the MAC address actually registered?? Because the MAC address of the ethernet port of the MBA and the MAC address of the wireless are different.
If the MAC addresses are not registered.. how does the Uni know the difference between a computer and a router??
You are not allow to run a router that feeds DHCP into the uni system.. but they cannot know what you have behind the MAC address of the item plugged in. A computer or a router.
So the TC has to be in bridging mode - which has worked perfectly well previously
Try releasing the MAC address to the PORT.. because the uni might have decided they don't want hubs connected either.. therefore the address of whichever device that is plugged into the wall is registered at the switch and will not allow a change for a fix period.. that is one way to stop people changing stuff around.
Try powering off the TC.. when you use another item.. or change from ethernet to wireless.. then power up the TC again and then power up the device .. eg the wireless on the laptop.. If it fails, it is not the TC that is causing it.. because in bridge the TC is completely dumb. It has no ability to control the MAC address being sent to the main router. None whatsoever.
If your TC recently upgraded to 7.6.4 firmware.. though.. well it can do all kinds of nasties.. flash it back to 7.6.1 and factory reset it.. and hope it works as it did before.. if not the uni changed the system to prevent your TC acting even as a hub.

Yesterday my wired connection worked, today it does not.

As I said in the title, it stopped connecting successfully from this morning. Usually it got connected at boot, via systemd and [email protected]
Now not only it doesn't do that, but even running dhcpcd manually won't work.
If I try systemctl status [email protected] I can see that it failed. First the reason was that it didn't get an IPV6 address, now it says "Network is unreachable". This is so weird. At first I thought the reason was that probably the router does not support IPV6, so I added ipv6.conf.all_disable_ipv6 = 1 (something like this, I don't remember exaclty) to /etc/systemd.conf.
Now nothing works...
Please help if you got any suggestions! Thanks in advance,
rubik

Can't connect by wired connection

I just moved into a new house, and ordered a fios connection through Surewest. I bought a LinkSys E3000 Wireless-N Router, and my iMac is connecting fine to the internet wirelessly...however I'm not getting anything when it's wired to the router.
In network settings it says "connected" in the ethernet section, yet if I turn "airport off" I can't load a single page (despite it saying the ethernet is "connected"). My router also shows that there's an active connection. So I connected the data cable directly from the port (the one that's inside the house, not on the router) to my computer, and I still had the same problem. I don't even know where to begin with, I'm not sure if it's a problem with my internet provider, my router, or my computer.

Hardwire the connection directly from your fios to the computer.
Go to the Network Pref Pane and go to Location > Edit.
Add a new location.
Click Apply at the bottom of the Network window.
Restart the computer.
Go back to the Network Pref Pane -- what is the IP address you have for your ethernet connection?
If you still don't have an internet connection and the IP address is valid (not 169 or 10 or 192) then power cycle your fios connection (if possible). I turn my modem off for at least 30 seconds if not 5 minutes.
If that doesn't take care of it, try your computer at a different hard wired connection (work, school, Apple Store, etc.). If it works some place else but not at home you may want to call Surewest to make sure they are not using provisioning / MAC Address filtering.
Hope that helps.

Can't connect to wireless network from my e2000 router

My network was working fine, then my router turned off spontaneously. The power wasn't lost, everything else in the power strip was still functioning. I got it working again but now I can't connect to the wifi network on any of my devices. I've tried using a Wii, an iPhone 5 and a Mac running OSX 10.7.5
The wired connection works fine. I can see the network on my list, but when I try to access it it reads "Could not join 'network'. A connection timeout occoured."
Any ideas? Anyone else have this issue and fix it? Is it time to go out and buy a new router?

Yes, reset is fine. I do believe firmware upgrade can fix a lot of things.
I usually use 1, 3, 6, 9, 11 wireless channels for better wireless coverage.
I use inssider software to determine the best wireless channel to use.
I make sure to that cordless phones, microwave ovens and other wireless transmitters are at least 10 meters away from the router. I also updated my wireless devices as much as possible. I think that is the key to my stable network.

WRTP54G Intermittent Wired Connection

I am using a WRTP54G and am having intermittent connections to my wired connections only, wireless is fine. The connection will drop out for a second or two then come right back. Sometimes there is no issue for a long time, more than 3-4 hours and sometimes it will happen 5-6 times a minute. I contacted my VOIP provider Viatalk and they said that I should contact linksys. I went through the Ask Linksys link and it suggested looking at the MTU size. I ran the test they said to do to determine the correct MTU size and it showed it did not need to be changed the 1472 value worked fine. So I set it to manual anyways and put 1500 for MTU and still have the issue. Thanks for any help someone can give.
Message Edited by cianciolo on 06-22-2008 04:29 PM

I have already contacted my service provider and they know of no issueon their side that would cause this. They said to contact linksys. The router is not from my service provider so they do not do firmware upgrades for it. But It does have the latest firmware I upgraded it myself from the Linksys wesbsite.
