OS X :: Snow Leopard Does Not Allow Me To Connect To 802.11n Networks?
Sep 4, 2009
I have an Airport Extreme card with the Atheros AR5416 chipset in my Mac mini (late 2007 rev.) and it worked perfectly in Leopard.
I could connect to my roommate's Airport Extreme just fine on its 802.11n network. But with multiple tries installing Snow Leopard it just has not worked to connect to that same network.
Despite the antenna only being connected to the connector for 5GHz networks, I can connect only to 802.11g (2.4GHz) networks but not 802.11n (5GHz) networks.
If the network card was defective I would expect Leopard to have similar issues but it was rock solid. Right now I am using an Airport Express as a bridge through ethernet to get internet connectivity.
This is something I fully expect to deal with in Linux or even Windows with old drivers, but certainly not on Apple's own OS on their own hardware.
Has anyone else had similar issues with Snow Leopard? Whether you do or not, what chipset does your Airport Extreme card use? You can get this info from Apple menu -> About this Mac -> More Info -> Airport -> Firmware version.
From what I understand, Apple is still using both Broadcom and Atheros chipsets in their Airport cards, so I'm curious to see if it's an issue with Atheros chipset drivers in particular.

We have an Xserve (intel) with two ethernet ports running on OS X 10.6.8 server. It is connected to our network and sharing files with local users and authentication from our PDC (over an AD network). I need to setup a private network so that we can keep a few PCs off of our primary network (primarily to keep them from getting updates pushed or malware). Using the two ethernet ports, this should be do-able. It's practically automatic on a couple Windows boxes we have setup. However, when I plug a small router into the second ethernet port, I instantly lose the PDC communication on the other. I'm not sure if there are other issues at this point or not because there hasn't been a time when I can bring the system down (yet).

I am currently attempting to assist a lady who is experiencing many issues connecting to wireless networks and using VPN software to connect to our resources. I will provide as much detail as I can, however this has been an ongoing job involving myself and quite a few other support officers. I am, historically, a PC user. I can provide some basic Mac support, but only what I have been trained in. I am now seeking assistance, as I have reached the limit of my knowledge. An issue was raised with myself when this lady first called and reported that she was having trouble connecting her VPN client (from Cisco) while connected to a remote wireless connection.
I went through some basic troubleshooting (what errors are you getting, etc.) and eventually discovered that the client was using a static IP (Self assigned in Mac-speak). I was perplexed that the lady would be using this and asked some more probing questions. Turns out, the hotel that she is staying in does not have any wireless connections available and she is using next doors' (shady, I know). One of her friends informed her that the best way to connect would be to use this static IP (10.1.1.2). This means that multiple computers would be connecting to the same network with the same IP address. I informed her that static IPs are meant to be unique to all computers on the network and that having overlapping ones may cause conflicts. When she changed this back to DHCP, she then lost all network activity. the Airport device was turned on, but not connected to anything......................

I have a 2008 imac which has built in wireless. Is there some way to use the wireless to connect to internet while using the ethernet jack to connect to a different LAN so it can connect to a fileserver? Or if that isn't possible, can I join my LAN network to the one which provides internet access without having to change all my LAN addresses? My goal is to maintain a private gigabit LAN while getting internet from somebody else in my office.

I have an apple airport (age unknown), but it is one that looks like a mushroom cap. I have a network set up in WPA2 format. A nintendo DS user wishes to connect to wifi, but requires a WEP set up. Can I run both kinds of network or must a switch back and forth (since I like WPA2 more)?

wondering if its possible to connect to two wireless networks to combine their connections and get a greater speed. in the 2 offices at work we have 2 separate wireless connections. one for the sales team, one for the support team. now my mac picks up both of them fine and i can connect. but im wondering can i connect to both networks and get a faster speed? i have a standard macbook (white one). would i need to buy a secondary wireless device like a usb wireless device and install that and connect to each network with each wireless device?
if yes how would i go about joining them together for combined speed. if not then can someone fill me in? or can i connect my standard mac wifi device to 2 networks at the same time? im a mac n00b - since last august so go easy on me

Just picked up my first mac, a brand new 13" MBP - which is awesome. I also have an AirPort Express that I've set up to use to play iTunes wirelessly to my external speakers. The problem is, my internet connection is coming off of another router (I live in a dorm-style place, so there is one shared internet connection). So far I've been able to either play music on my external speakers, or connect to the internet, but not both.
Am I doing something wrong? Is it possible to do both at once?

I installed XP, via BC, on my older 20" iMac, and I keep getting an error message when trying to connect to my wireless network. My network shows that it is available, with full signal strength, but as soon as I try to connect to it, I get an error message saying that it may be out of range, and I should refresh and try to connect again.

I have a Macbook Pro running Leopard 10.5.5 purchased in early October 2008. for a few days I could get onto free wireless networks with Airport, however starting 2 weeks ago I cannot. there's no problem establishing an IP address. steps taken: talked to Applecare who told me I need new wireless card and told me to bring into apple store. apple store yesterday they told me it was a problem with the "preferred locations" function clogging things up so they cleared my cache and set everything to "automatic," unchecked box that says remember networks, and of course it worked fine. this morning it doesn't. once again I cannot get onto an open wireless network. also a new detail is that now when I connect my ethernet cable after trying Airport first I cannot connect, I need to restart computer 1st.

I'm looking to have 5 mac pros networked somehow to all work off the same external drive. I haven't bought the drive or network device yet. The computers will simply need to playback, copy and delete videos from this external drive.

My MacBook Pro (17" from mid 2010 running OS X 10.9.4) won't connect to some "open" wireless networks. The ones it has problems with are typically in hotels and are the kind where a login screen is supposed to be presented after selecting the network. Instead of getting the login page I get the message that I can't join the network and am prompted to cancel or run all the diagnostics (which aren't useful).
My laptop seems to be the only one in my family that has this problem. We've been places where out of 8 wireless devices (4 Mac laptops and 4 iPhones) my MacBook Pro is the ONLY one that won't connect. My wife's MacBook Air always connects like a champ. And my MacBook seems to work fine on most secured networks, such as here at home.
Info:
MacBook Air, Mac OS X (10.6)

I recently signed up for AT&T u-verse. As part of that service they provide you with a 2wire router. Initially my MacBook Pro (running the most recent osx) was connecting to this router fine. But, because i like the interface of my Airport Extreme router better, i decided to run a router-behind-router setup, to set up a network with my airport extreme. In other words, i ran a hardwire out of the 2wire router into my Airport Extreme, thereby allowing the airport extreme to disperse wireless signal as well. Therefore, there are currently 2 wireless networks in my house, one being dispersed from the 2wire router, and the other from my airport extreme. Both wireless networks are password protected in WEP-2.
Now i can no longer connect to the 2wire router. Everytime i try to do so, the system prompts me to type in the WEP password for the 2 wire router and upon doing so, it indicates that the password failed, the connection timed out, or that the connection failed. I've monitored the network preference pane as i'm trying to connect, and it invariably indicates that there is "NO IP ADDRESS" for the 2wire network. In fact, i can no longer connect to ANY OTHER wireless network which is password protected. It always gives me this same dilemma. The only password protected network i CAN connect to is my airport extreme network. Does anyone know what the hell is going on here? I'm completely baffled. I've gone so far as to delete all preferred networks from my system. Delete all network related passwords in the keychain access. and also to delete my network related preferences in Library ---> Preferences, to remove any 'confusion' the system might be having, but to no avail.

I have a wireless network router/internet thing in one room of the house and my g5 is in another room. I also have a PC laptop and that can connect to my home's wirless internet no problem. My G5 simply cannot connect or even sense my 2wire901 home network, but it can see other networks in my home area. I only managed to connect to my own home network once! And the 2nd time my 2wire901 can never be found. Get this; it has to be the mac. Coz my laptop is sitting right next to my mac in 1 room and it has no problems connecting.

Likely not useful for most of you - but for anyone who happens to use Juniper Network's Network Connect app for ssl VPN access, here's how to fix post SL install. Apparently, SL messes with perms and removes the 'Frameworks' dir.
[URL]
Code:
sudo chmod 755 /usr/local/juniper/nc/[version number]/
sudo mkdir '/Applications/Network Connect.app/Contents/Frameworks'
Tested, works like a charm.

I was running 10.5.8 on my Mac Pro, and I had file letters mapped in Vista to all of my Mac Pro's drives. Post-upgrade, I can no longer connect to any of the drives -- I can see the Mac Pro in my Network window in Windows, but double-clicking on the Mac Pro results in a password prompt in which no password is accepted. Obviously something has changed on the Mac. I've gone through the Network dialog boxes in 10.6, but can't find any culprit.

Other macs on my network have no trouble connecting, just the macbook pro, so it's not the router or ISP. This laptop previously had no trouble connecting to the internet on this network. It continually says ISP failed (airport, airport status and network settings are all green). Laptop running 10.6.8. I tried turning Configure IPv6 off, no change.

My Mac Mini Server with 10.6.8 Snow Leopard Server doesn't connect to the Internet.It can connect to the router either via Ethernet or Airport, but it can not get an IP address -- it always assigns itself a random IP address which is not in the correct range for the router.All other devices, including PC, iPhone and iPad can work correctly with the router.When I manually typed in the router's IP in Safari, 192.168.0.1, I can see the router admin page. But typing in any external IP nothing shows up.Thinking it might be the router's problem, I used iPhone 4S' tethering tried wifi, USB, Bluetooth tethering and the Mac Mini still doesn't have any Internet connection.I changed the DNS in the Network preferences, trying Google's public DNS 8.8.8.8, my ISP's DNS, and empty DNS.

I have a MacBook Pro running 10.6.8 and we got wifi at the house this afternoon. It will not connect, if I open network diagnostics the top four lights are green, internet and server are red. There are two other macbooks in the house(at least one also running 10.6.8) and two ipads, all of which connect with no problem.

I am able to see my server shares when I connect my bacbook pro via cable, but when i connect via wifi the network shares are not visible. a windows laptop connecting over the same wifi router can see the server shares. Does OS x 10.6 use a different port that I need to open on my wireless router?

I am running multiple services with the latest version of OS X 10.6 Server on my MacMini (web, mail, ichat, address book, etc.) . When I try to open my websites I get an "unable to find sever message". Everything has been working fine for the last 2 years and no changes have been made to the server settings, ISP, or DNS. All other services are working as they should. The server is hooked up to an Airport Extreme via a cable modem with a static IP. I have tried the following thus far:
1) restarted the server, airport extreme, and cable modem
2) checked the DNS via the web and my site addresses are pointing to my static IP address
3) turned Web services off and on again in Server Admin
4) checked the Airport port mapping to make sure Web Service (Port 80) was still open

I've just enabled Web Shareing, I think for the first time, on an old Powerbook G4. From the links in the System Preferances panel, I was able to see the 'computer' web site, but not the 'personal' one. Taking the problem to be that described in [URL], I followed the instructions in [URL]
Rather than the 403 I was getting, I now just see 'Safari cant open the page [URL] because Safari cant connect to the server macintosh.lan.'running the apachectl configtest commend. I did that, and got the following:
/usr/sbin/apachectl: line 73: ulimit: open files: cannot modify limit: Invalid argument
Syntax error on line 1 of /private/etc/apache2/users/James.conf:
Invalid command 'James/Sites/"', perhaps misspelled or defined by a module not included in the server configuration
how to get the sites folder running?

I use Citrix Web to access my office network. It was working fine on my iMac for several after I installed Snow Leopard. But today, I'm getting an odd error message. I log in, and then a box pops up that says I need to make sure that the remote server is listening on Port 1494. I am not able to connect to my office network. Has Snow Leopard changed anything so that another program is using that port? I have not upgraded my Macbook yet and I was able to connect, so I don't think my office network is the problem. I have tried Safari in both 32 bit and 64 bit, and I've tried more than one Citrix client. So there must be setting on my computer I need to change - if I could only determine what it is.

I have one of every type of the newest Macs: MacBook, MacBook Pro, MacBook Air, iMac, Mac mini, Mac Pro. Since upgrading them to Snow Leopard, none of them will connect to any wireless network -- regardless of the router (AirPort, Linksys, Cisco, etc.) and regardless of the type of security (open, WEP, WPA, etc.).
Every time I attempt to connect, I get the message that the "connection failed." Here's a 20 second screen recording of what's happening.

After extensive Googling, I need to take a break, and find out if someone with more experience knows what I can try next...
I'm not the best when it comes to Networks, or even router configuration. I'll just put that out there, in case I've missed something obvious.
My router connection (DLink 2640B) was working perfectly fine before I upgraded to Snow Leopard. Now I cannot connect to any wireless network, and I cannot connect to the router administration page, either
(192.168.1.1).
The internet connection still works fine on two other laptops. Also, I can connect this iMac via the ethernet cable.
I've tried deleting the files NetworkInterfaces.plist, com.apple.network.identification.plist, and preferences.plist; I've tried rebooting my router; I've tried creating a new network. Airport sees all the networks, tries to connect, then it just says that it fails.
