DNS? error preventing fileshare over WiFi

I have a WRT54G connected to a cable modem, a NAS, a Wireless Print Server and a new WHS. I am able to access the internet and each of the other networked devices when connected to the WRT54G via Ethernet. However, when connected to the WRT54G via Wi-Fi, the Internet is available but the shares aren't resolved by host name. The shares can be accessed by IP.
I'm stumped. Any ideas?

Try to upgrade the firmware of your Router. Go to website linksysbycisco.com/downloads.........insert model no of your router in search tab......select proper version of your router........download the firmware file......save that file on desktop
Follow these steps to upgrade the firmware on the device : -
Open an Internet Explorer browser page on a computer hard wired to the router...In the address bar type - 192.168.1.1...Leave the Username blank & in Password use admin in lower case...
Click on the 'Administration' tab- Then click on the 'Firmware Upgrade' sub tab- Here click on 'Browse' and browse the .bin firmware file and click on "Upgrade"...
Wait for few seconds until it shows that "Upgrade is successful" After the firmware upgrade, click on "Reboot" and you will be returned back to the same page OR it will say "Page cannot be displayed".
Now reset your router :
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...

Anyone still experiencing errors when syncing over WiFi?

I have upgraded to the latest version of iTunes and I still get this error... "An (iPhone/iPad) has been detected, but it could not be identified properly. Please disconnect and reconnect the iPhone, and try again." There are less errors than with the previous version of iTunes, but this error is still very annoying and causes the sync to pause until dismissed. Anyone have a solution?

Greetings,
That be normal, my friend. You can use the cable that came with the iPhone, or use WiFi, either way works fine.
Cheers,
M.

Can't get email over wifi at home, but can at work.

Okay, I think this is a problem with settings on my time capsule, but I can't figure out what. On my iPhone 5 and wife's iPad I can get email over the cellular network and over wifi at work. I can't get email over wifi at home, get a can't connect to server error. Also had a friend, who uses the same ISP, try with his android phone - same error, but works over wifi at his house. Since I can get email over cellular and wifi at work, I'm fairly confident that I have the server settings correct. Any ideas?
Thanks.

Was facing a similar issue with my friend's iPad (Latest one). Forcing the DNS Server to 8.8.8.8 (I think Google's DNS servers) fixes this issue. I had faced something similar on my iMac a long time back. Something a little strange about how Apple products do a DNS lookup? Not sure if it is an issue with the response time of the DNS servers as well..
In any case, the good news was changing it to 8.8.8.8 worked.. Luckily the iPad's network configuration tool allows you to navigate to the pane where you can see the DHCP supplied IP addresses and just go to the DNS field, delete what was present there and force it to this address.
The difficulty in coming to this conclusion was the fact that the browser works fine for all the sites we had tried. It is mostly the apps that had trouble, and the App store also was inconsistent in reporting details..

I am trying to download iOS 5.1 on my iPhone and iPad. Both times it tries connecting to the software update server and just hangs there. I've tried doing both over wifi and get error message. What do I do?

I cannot download the ios 5.1. I'v tried doing it through itunes after downloading the latest itunes. It says that my phone and ipad both have new updates and tries to coonect to update software server. That is where it hangs up and just keeps trying to connect but never does. Then when I try to update my devices over wifi, it tries and thens gives me a download failed message after a few minutes. What do I do?

This has solved loads of people who have this issue and have used an alternate DNS setting. Below are instructions for both iPhone OTA and on you Mac
If you are getting the error message "Unable to check for update" when you try an OTA (over the air update)
Change DNS Servers
Settings -> Wi-Fi
Click the blue arrow on your connected network
Delete everything in DNS and replace it with 208.67.222.222, 208.67.220.220
Try again
If this works, you will probably want to remove the WiFi network using "Forget This Network" and then reconnect to it to get your original DNS servers back. Alternatively, make a note of the original DNS servers before deleting them and replace it after you are done.
If you are getting the error message "Unable to check for update" when you try through iTunes
On your Mac
Choose Apple menu > System Preferences, and then click Network.
Select the network connection service you want to use (such as Wi-Fi or Ethernet, unless you named it something else) from the list, and then click Advanced.
Click DNS, and then click Add at the bottom of the DNS Servers list. Enter the IPv4 address for the DNS server.
You can use OpenDNS
208.67.222.222
208.67.220.220
or
You can Google Public DNS if you want
8.8.8.8
8.8.4.4
I have actually repointed my routers DNS so all my devices now point to OpenDNS servers

I can't connect to Internet anymore (WIFI or Ethernet). This was working perfectly before. I don't get a proper IP address from my ADSL box and it seems there is a DNS error when accessing the Internet.

I have an issue with my MacBook pro (MAC OS X 10.8.3) when trying to access Internet. I am behind an ADSL box (Orange). I have a PC on the same LAN which accesses Internet perfectly via the same Box.
On the MAC, I have tried WIFI and Ethernet. And have same issue on both. I have checked the IP address (the ADSL box is a DHCP server) but the MAC doesn't get a proper IP and network mask I tried a manual IP address setup and it doesn't get better. I have setup the DNS servers for my Internet provider, but I get DNS error. I have tried 2 Internet browsers (Chrome and Safari), both have the same issue.
I tried to put my MAC on a different ADSL box (I have 2 acccesses with 2 providers at home) and get the same issue.
I also noticed a havy CPU load on the mDNSResponder process (at least 30%). I have restarted it, but no improvement.
Last, I have repared the permissions.
From those trials, it seems that the problem is on the Mac side. But I am completelly without any new idea, so I need help
Thanks

Please read this whole message before doing anything.
This procedure is a diagnostic test. It’s unlikely to solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
The purpose of the test is to determine whether the problem is caused by third-party software that loads automatically at startup or login, or by a peripheral device.
Disconnect all wired peripherals except those needed for the test, and remove all aftermarket expansion cards. Boot in safe mode and log in to the account with the problem. Note: If FileVault is enabled, or if a firmware password is set, or if the boot volume is a software RAID, you can’t do this. Ask for further instructions.
Safe mode is much slower to boot and run than normal, and some things won’t work at all, including Wi-Fi on certain iMacs. The next normal boot may also be somewhat slow.
The login screen appears even if you usually log in automatically. You must know your login password in order to log in. If you’ve forgotten the password, you will need to reset it before you begin. Test while in safe mode. Same problem? After testing, reboot as usual (i.e., not in safe mode) and verify that you still have the problem. Post the results of the test.

How to prevent itunes from connecting to my IOS devices over wifi

I have a MBP retina that is set to sync (over wifi) with the iOS devices for myself and my wife: 2 ipads, 1 ipad mini and 2 iphones.
When I am launch iTunes in my other Mac - Macbook Air (mid 2010, 13inch, OS X 10.8.2), it will also start to connect the iOS devices - even though I am not using it to sync with my iOS devices.
How to prevent iTunes in my MBA from connecting to all the iOS devices in my house?
Thanks.

I configured all my iOS devices to sync with my MBP Retina (over wifi) - but the problem is that when I am using my MBA, the devices will also automatically connect to the MBA Itunes over wifi when I launch iTunes in the MBA.
Is there any way to prevent auto connection to the MBA?

Why does Time Machine not work over wifi but only via ethernet cable ?

Hi everyone,
It's been some time I have this problem now.
The first time I backed up my mac within Time Capsule with time machine, I chose to use the ethernet cable because the gigabit connection is much faster than the wifi for the first back up, but now, any time I want to update this back up, I need to connect the cable, cause "Time Machine can not connect to the Drive I picked" over wifi.
This is so annoying. Does anyone have a similar issue ?
Any solution ?
When I got this "error" I can use Utility Airport and get full access to the drive, even in finder. The only thing that doesn't work is TimeMachine connecting to the drive, even if it is detected by TimeMachine itself.
Thanks.
Riccardo

Typical Yosemite.
I suggest a full reconfigure of the TC.
Follow this list..
No files are deleted on the TC doing this although you might have to repoint your laptop to the backup.
Note.. even if TM does connect it will say it is going to do a new backup.. it is only when it starts that it discovers the backup exists and increments it.
Start from a factory reset. No files are lost on the hard disk doing this.
Factory reset universal
Power off the TC.. ie pull the power cord or power off at the wall.. wait 10sec.. hold in the reset button.. be gentle.. power on again still holding in reset.. and keep holding it in for another 10sec. You may need some help as it is hard to both hold in reset and apply power. It will show success by rapidly blinking the front led. Release the reset.. and wait a couple of min for the TC to reset and come back with factory settings. If the front LED doesn’t blink rapidly you missed it and simply try again. The reset is fairly fragile in these.. press it so you feel it just click and no more.. I have seen people bend the lever or even break it. I use a toothpick as tool.
N.B. None of your files on the hard disk of the TC are deleted.. this simply clears out the router settings of the TC.
Setup the TC again.
Then redo the setup from the computer with Yosemite.
1. Use very short names.. NOT APPLE RECOMMENDED names. No spaces and pure alphanumerics.
eg TCgen5 for basestation and and TCwifi wireless name.
If the issue is wireless use TC24ghz and TC5ghz with fixed channels as this also seems to help stop the nonsense. But this can be tried in the second round. ie plan on a first and second round of changes to fix this.. hopefully.. I will point out other steps that can be round2.
2. Use all passwords that also comply with 1. but can be a bit longer. ie 8-20 characters mixed case and numbers.. no non-alphanumerics.
3. If the TC is main router you can skip this point. This is only an issue when the TC is bridged.
Ensure the TC always takes the same IP address.. you will need to do this on the main router using dhcp reservation.. or a bit more complex setup using static IP in the TC. But this is important.. having IP drift all over the place when Yosemite cannot remember its own name for 5 min after a reboot makes for poor networking.
4. Check your share name on the computer is not changing.. make sure it also complies with the above.. short no spaces and pure alphanumeric.. but this change will mess up your TM backup.. so be prepared to do a new full backup. Sorry.. keep this one for second round if you want to avoid a new backup.
5. Mount the TC disk in the computer manually.
In Finder, Go, Connect to server from the top menu,
Type in SMB://192.168.0.254 (or whatever the TC ip is which you have now made static. As a router by default it is 10.0.1.1 and I encourage people to stick with that unless you know what you are doing).
You can use name.. SMB://TCgen5.local where you replace TCgen5 with your TC name.. local is the default domain of the TC and doesn't change.
However names are not so easy as IP address.. nor as reliable. At least not in Yosemite they aren't. The domain can also be an issue if you are not plugged or wireless directly to the TC.
6. Make sure IPv6 is set to link-local only in the computer. For example wireless open the network preferences, wireless and advanced / TCP/IP.. and fix the IPv6. to link-local only. Do the same for ethernet if you use it.
There is a lot more jiggery pokery you can try but the above is a good start.. if you find it still unreliable.. don't be surprised.
You might need to do some more work on the computer itself. eg Reset the PRAM.. has helped some people. Clean install of the OS is also helpful if you upgrade installed.
Tell us how you go.
Someone posted a solution.. See this thread.
Macbook can't find Time Capsule anymore
Start from the bottom and work up.. I have a list of good network practice changes but I have avoided Yosemites bug heaven.
Yosemite has serious DNS bug in the networking application.. here is the lets say more arcane method of fixing it by doing a network transplant from mavericks.

IOS devices and Exchange won't connect over Wifi

Neither my ipad nor my iphone 5 will connect with my exchange server over my wifi network. The problem is limited to IOS devices on wifi and Exchange. The phone will connect with exchange over the cellular network. My windows laptop works fine over wifi with exchange and everything else. The ipad and iphone will connect to wifi and have no problems with web browsing, gmail, etc. I've used both devices successfully for months and the problem started yesterday. I did not do any IOS updates yesterday.
iPad and iPhone are both on IOS 7.0.4
The message on the screen: Cannot Get Mail. Server error. Contact your server administrator.
It also says: Cannot Get Mail. The connection to the server failed.
What I've tried:
Resetting network settings (only tried on iPad, since it didn't work)
Powering off each device then turning back on
Powered down the wireless router and powered back up
Confirmed with the exhange hosting company (GoDaddy) that they've made no changes

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

Note - When troubleshooting wifi connection problems, don't hold your iPad by hand. There have been a few reports that holding the iPad by hand, seems to attenuate the wifi signal.
Some Wi-Fi losses may stem from a problematic interaction between Wi-Fi and cellular data connections. Numerous users have found that turning off Cellular Data in Settings gets their Wi-Fi working again.
You may have many apps open which can possibly cause the slowdown and possibly the loss of wifi. In iOS 4-6 double tap your Home button & at the bottom of the screen you will see the icons of all open apps. Close those you are not using by pressing on an icon until all icons wiggle - then tap the minus sign. For iOS 7 users, there’s an easy way to see which apps are open in order to close them. By double-tapping the home button on your iPhone or iPad, the new multitasking feature in iOS 7 shows full page previews of all your open apps. Simply scroll horizontally to see all your apps, and close the apps with a simple flick towards the top of the screen.

Exchange Emails over WiFi

For the last 3 days or so, I'm not able to get my exchange emails over wifi on my mac and iPhone 5 (mail app). The home wifi is working just fine as i'm able to connect and get all the other mails from gmail and hotmail but when it comes to my exchange account, I get an error 'can't connect due to network error'.
Although, I'm able to get my exchange emails over cellular data connection both on my mac and iPhone. Please suggest.

Hi Razmee,
Thanks for the reply. I've tried that but my IT guys are a nocturnal bunch of grumps. It's not officially a work appliance, therefore not officially their problem. The fact I spend my own dollars to improve my efficiency and contactability is lost on them.
Cheers

Syncing with iTunes over wifi doesn't work

My iTunes sometimes does not recognize my iPhone... but sometimes it does. When I click to sync it will start but it will get an error eventually like "Sync failed to start" or "Unknown error -50".
I am not sure why iTunes will not sync. It used to work, but lately it hasn't been.
I put a bunch of new music on iTunes yesterday from old CD's I had and when I went to sync it showed it did, but when I went to play my music on my iPhone all the songs were just grayed out so I couldn't click on them....
so I used to USB cord and it synced fine...
So can it not send that much data over wifi or something?
I'm using iTunes on my Windows 7 laptop. I also have an iPad it won't sync with either.
Thx.

Which application are you trying to use?
The manual mentions setting up an NMEA port where you post describes a COM port. In the printing world a COM port is a USB physical port or oldschool Serial port. These may not be the same thing which might explain why your app is not working.
Lookup your installed ports (WinXP):
1. Navigate to Start > Run
2. Enter "cmd"
3. Click OK
4. Enter "netstat -a"
5. Scroll through the list and review all available ports
If your port is not mentioned above by the port number you selected from the Wi-Fi over GPS screen then it is not active and will not be useful for your apps. From the manual it looks like the default port number is 10110.
I would check the support site for your application to see if it is compatible with NMEA. They might have more steps for you on how to configure your app to utilize the GPS over WiFi feature of the MiFi.

Can Time Machine back up to a Western Digital "My Passport Wireless" over wifi?

I bought a Western Digital "My Passport Wireless" external hard drive / NAS to use as a Time Machine backup for my new MacBook Pro. I plugged it in via USB, formatted it to HFS+, and ran Time Machine. All good.
This hard drive has a wireless chip in it, so one can connect to it via wifi, either directly or through a router. When I dismounted the drive and connected via wifi (via my router), my expectation was that I could run Time Machine and do periodic back-ups without having to remember to plug in the drive, etc.
I can see the drive and read/write to it. I am connected as 'admin', not 'guest'. It is named "MyPassport", both when connected via USB and via wifi. When I try to use the drive via wifi for Time Machine, I'm asked: "Do you want to stop backing up to “MyPassport” and use “TimeMachineBackup/TimeMachine” instead, or back up to both?" When I select "Use both", I'm then told: "Time Machine can’t access the backup disk “TimeMachineBackup/TimeMachine”. The operation couldn’t be completed. (OSStatus error 2.)"
Should it be possible for Time Machine to recognize the same archive, whether connected via USB or wifi?
If I cannot, can I at least back up a new archive over wifi. I recognize that the first go at this would take a long time due to slow wireless transfer speed. What does OSStatus error 2 mean?

So you think that you know better than Apple.
NAS is not supported by Time Machine, you can take all the risks you like but do not advise others to do so. It doesn't matter what WD say, they want you to buy one, Apple are the deciders of what is supported or not.
Here's what WD say:
Note: WD does not provide technical support for Time Machine related issues. For assistance with backing up to a WD NAS drive, using the Time Machine application please contact Apple. As the backup application is built into the OS, they are the only ones qualified to diagnose a Time Machine related issue.
Good luck.

MMS over WiFi not working after Sense 6 Update

A week ago Monday, the Sense 6 update hit my phone. Once loaded, I could no longer send MMS over WiFi, stream Google Play Music over WiFi, access my content on Google Play Books, or back up my pics to Google Cloud over WiFi. After several days of e-mails back and forth with HTC, it was determined that I had to perform a Hard Reset and lose all my information. This after clearing the cache, re-booting, various Safe Mode re-boots, etc. Nothing worked. I finally gave in and performed the hard reset. Now, the only thing NOT working is MMS over WiFi. I've tried other WiFi networks and still no MMS functionality. After about 10 minutes, I get a red triangle next to the message and an error notification, "Generic Network Failure."
This is going to start costing me money. Like so many of us, I no longer have unlimited data. Now, every time I want to send an MMS, I have to use my data plan. Not cool. I'm hoping that someone sees this and is working on the problem. I love my HTC One (M7), I really do. But, we're talking basic smart phone functionality. Without it, I'll be looking for another phone, and perhaps even another carrier. I'd prefer not to do that, but so be it. Please, Verizon, a little help?
For what it's worth, the MMS does this first. Notice the little MMS icon with the clock lower right...it just hangs there first...and sorry about the shoe pic.
Next, it does the Red Triangle thing...
And that's all I know. Perhaps someone here, or a kindly VZW employee will see this and take pity. Thanks!

I am having the exact same issue with my HTC one, which started immediately after updating to sense 6. Very annoying since I do not have unlimited mobile data plan, so I have to manually turn mobile data on each time I want to send or receive mms texts, including texts with multiple recipients. Did not have this issue before the update. Love this phone, my very first smartphone. But it is hard to believe that I was able to send pics over text with my old flip phone with no data plan. And now I can't with the HTC. I just can't have the mobile data on at all Times. It has become very inconvenient ever since the upgrade. Wish I had never done sense 6.

Can't access some sites over WIFI (app store and more)

HI,
Not sure really where I can post this, but hoping someone will have a lead as it's very frustrating.
I have a belkin N router, and for some reason over wifi some sites do not work. I cannot access the Appstore on 2 iphones, I get error message that can't connect. the weird thing is that my ipad has never had problems with this and always connects to app store without problems.
I tried resetting my router and disabling security, still doesn't help.
I'm at a lost, any help greatly appreciated.
Latest firmware installed. iPhone 4 and 5 have the probelm as does my MBP which has problems connecting to some sites.

Try resetting Safari, safari under safari menu, empty Chache. Safari preferences>privacy, remove all website data. Also safari prefernces>security>unclick enable Java, leave Java script clikced. You can have corrupted cookies(they will re-create) Hope this helps.

ITunes - syncing over WiFi with iOS 7

Ever since upgrading two phones to iOS 7, iTunes is spamming the console with constant disconnects:
[date] server iTunes[pid]: Entered:_AMMuxedDeviceDisconnected, mux-device:id
[date] server iTunes[pid]: Entered:__thr_AMMuxedDeviceDisconnected, mux-device:id
etc etc
This goes on for a while, about every 2 minutes, until iTunes hangs.
Originally, I'd set up these phones to sync over WiFi. After switching this off – only for the devices on iOS 7 – the above errors stop ocurring. Again, this doesn't happen with iOS 6 devices.
Running a Mac mini with Mac OS X 10.7.5.
Any ideas beyond switching off WiFi syncing – which is really inconvenient...

Thank you very much!

My Time Machine backups are significantly larger, and slower, over WiFi than Ethernet

My regular hourly backups from my Time Capsule began acting up a month ago. They were abnormally large (25-100 MBs) and took a long time--once, six hours.
I connected my Time Capsule to my MacBook Air through ethernet to repair the disk through Disk Utility, (I turned Airport off on the Air, but not the Time Capsule), and then to rebuild the Spotlight index for the Time Capsule.
Backups over ethernet work just fine now. The backup will happen in two parts, of around 200 KB each, and take two or two and a half minutes. But when I turn Airport on the Air back on, reconnect to the WiFi network, unplug the ethernet cable, and immediately start a new backup over WiFi, the two parts balloon to around 20 MB each, and the backup takes hours.
This is a backup over ethernet, which took 2 minutes, 21 seconds:

I live in an apartment building so there are a number of WiFi networks around.
Not to mention cordless phones, microwaves, etc., any of which can interfere.
On iStumbler, my network shows up twice--once on channel 149, with signal strength of 50-65% and noise of 15%--and again on channel 10, with signal strength of that wildly varies from 20% to 90% and noise of 20%. Other networks in the building are on channels 1, 2, 6, and 11. The graph of channel 149 is very smooth, while the graph of channel 10 is choppy.
It's probably using 149, as those numbers are pretty good. Press Alt/Option before clicking the Airport icon in your menubar to see which band it's using.
Watch the band it's using while running a backup. Try other channels in the area of 149. Unfortunately, it's a bit of a "hit and miss" thing.
Why are there two networks? Is that part of the problem? My Time Capsule is located about three feet right and a foot below my desk, so I can't think of a reason why it wouldn't be 100% for both channels.
It's a dual-band router. As I understand it, OSX will pick the best signal.
I really want to know I have a clean, safe, accessible back-up before I replace it though. Right now I don't trust the Time Capsule.
Do at least your last backup via Ethernet.
