• Questions of signals (s7 edge LTE - iPhone 7 Plus 4 G/E)

  Hey guys,.

  I know there are a lot of posts on this topic but I can't really find the one that corresponds to this...

  So I moved from s7 Edge for iPhone 7 more.  Since the switch, I have signal problems. Where, normally, I LTE 3 bars on my edge of s7, I now get 4g and E even on my iPhone 7 more. What is going on!!!  BTW, I'm on T-Mobile.

  Thank you

  Hey Greggaa,

  Thank you for being a part of the communities of Apple Support.

  If you get a poor cellular signal where you used to get full LTE signal, then it might be an update available for your iPhone carrier.  Please follow the steps in the article to check this update:

  Update the settings of your company on your iPhone or iPad

  Take care.

• iOS 10 no signal problem

  I have an iPhone 5s (model 1533) and after the update to iOS 10 I can't get a signal, I tried a full restore and update and also reset network as well as the obvious reboot. First, he would get a signal a little while but if I tried to make a call, it would go directly to no signal, it also seems to have the power of the weak wifi signal too, related? Must say that I had a lot of problems with my apple stuff recently, at the end of my home! All ideas welcome please?

  I had the same problem on Verizon.  I fixed mine by going to settings, cell and disable roaming data and then on again.  Its happened twice so far, as well as a few other bugs.  iOS 10 is probably the worst launch of iOS.

• Why my MB Air decreases the wifi signal

  My 2012 13 "core i5 MacBook Air running different operating systems will remove the wifi signal and it is getting worse. someone at - it a reason why?

  How your MacBook Air running different OS version? However, the Wi - Fi signal fell to each version?

  This always was a problem or just started to happen? Up to now, what did you do to try to solve?

• The dual SSID Signal interference

  I have the cable and Internet provided by AT & T.  I mainly had Comcast when you live in different parts of the country.  I am owner of an Airport Extreme and Time Capsule I used previously to set up the network internal in addition to the SSID broadcast material of the cable company.  I never had a problem before using AT & T.  I noticed that the Internet speeds both the provider of cable and speed on the internal network have been seriously degraded.  I was unable to stream movies.  After several attempts to solve the problems with AT & T and myself, I found the problem: it seems to be interference of signals between AT & T and Airport Extreme material each broadcasting separate SSID in very close to one another.  I got the Apple hardware, and the problem was solved immediately.  While I'm happy to have it fixed, I don't miss the advantage of having the internal network using Apple devices.  What are my options?  Is it correct that I can't use the Apple devices to extend the SSID signal emissions equipment AT & T?  I think the problem might be solved, perhaps, if the two gateways were not close to one another, but I do not have another spot to plug the Airport Extreme.

  Is it correct that I can't use the Apple devices to extend the SSID signal emissions equipment AT & T?

  Unfortunately correct.

  Apple routers work that to extend another router from Apple... no other brand is invited to the party.

  I think the problem might be solved, perhaps, if the two gateways were not close to one another, but I do not have another spot to plug the Airport Extreme.

  Separate the two routers as much as you can... I always recommend 6feet or about 2 M. If they are closer than this really a wireless should be turned off. Only for this case deactivate the ATT router instead of your apple.

  There are enough wireless channels to run 3 wireless routers close to each other.

  Sometimes the automatic separation of channels does not work and you need to get and change physically.

  Use wireless diagnostics (many versions available, but it is built into Mac OS since the Mountain Lion)

  There are a bunch of tools... the actual diagnosis is not particularly useful in my experience.

  

  Open scan.

  

  You will need to click on it to see the whole thing.

  Now, I have a few questions... first, I'm not showing noise... This is just my configuration problem. But you should see RSSI (signal level), noise, channel, band, width and country.

  Watch channels... My installation has some problems because most of the 2.4 ghz is using channel 11.

  The diagnosis tells you even what channels to use.

  

  I can open airport utility and select one of the units in issue. Click the icon from the airport... Click on edit in the preview.

  

  Go to the wireless tab.

  

  Click Wireless options

  

  Change the automatic 2.4 ghz regardless of the channel you want.

  

  Save and update from the airport.

  Especially for 5 GHz, I think that your stay on auto should be fine. It is more short-range and isn't usually a big problem.

  Note also the signal strength really counts... things go wrong if you don't have enough separation and the signal strength is low.

  2.4 GHz, there are only 3 channels Alcan... 1, 6, 11

  Although Diagnostics of scanning you will offer between channels... do not be fooled that this corrects the problem.

  Read the wiki for wireless lan.

  https://en.Wikipedia.org/wiki/List_of_WLAN_channels

  Channel 6 for example is actually peak signal to 6, but it covers 4 to 8.

• No signal iPhone 7 more

  I was able to find an iPhone 7 more black well, worked all day, slept and next morning no cell report real message was no Service.  I tried resetting network services, remove the SIM card, reset the phone.  I tried same sim in another phone and it works.  Seems to be a similar issue to those who have the problem of airplane mode.  There is now no point on the phone that I want and I'm stuck with a dead paper weigh.  Any ideas?

  I have a similar problem. I have an iPhone 7 Verizon and it also loses the signal while driving. It says no Service. Restart the phone temporarily solves the problem. I called Verizon and they have other reports and said that Apple is aware of the issue. I hope it's just a software fix!

• I have an imac 27 "... on power there is no signal to startap, usb ports are not working and its deadlock with the logo of the Apple with the circle of rotation... Help, please

  I have an imac 27 "... on power there is no signal to startap, usb ports are not working and its deadlock with the logo of the Apple with the circle of rotation... Help, please

  Wake the computer to your Apple store or Apple authorized service for the service provider. He probably suffered a hardware failure.

• The music does not open even when no signal.

  I have a spotty cell service where I live. When at work and I am in one of these areas of service not, my music even will not open. I saved music to play offline, but the screen is not yet open. (If I'm in a 'dead zone') no cell signal) does not even open the music.  It searches only. I can't open until I again service.

  Really? Argh! It will be a nightmare when I travel through the mountains of Colorado.  Looks like I'll be getting my Nano out of retirement.

• IPhone 6s signal problem

  I bought 6 s 2 weeks ago.

  I found my 6s signal strength is less than 6 s of my friends, with the same telco provider.

  We put our phone next door. And my 6s has shown more low-power signal compared to theirs.

  Can I know how to check?

  Or is my issue 6s quality?

  I use case TPU of military. The seller case used force to push my 6s in the case initially.

  The team would cause damage to the antenna and the cause of my weaker signal?

  Please help and advise. Sincerely, I'm looking at your comments.

  Another way to test is to make sure that the two devices are out of the case and test. It is very possible, the case that you use, and by your own admission, your phone was forced to, causes the degradation of the signal.

• Problem with the complete signal of roaming

  Hi all

  My iphone 6s had served 10 months and very well, starting this week, I continue to have this (loading icon displayed next to the 3 G icon) roaming issue once every day what all my apps have no data carrier suddenly then the signal is full(4/5-dots), my phone is only able to find roaming after flight mode reset. Someone knows how to solve or having the same case with that? is this problem just iOS?

  -seems to happen after I have updated to iOS 9.3.5

  -I am using network of 3 / 4 G in Hong Kong

  -J' I reboot my phone twice and still get

  -C' is *.

  BR

  If the signal is good, but you don't get downloads of data, you must contact your service. They might be limiting your speed down.

• Video signal splitter unrecognized DVI - two different devices! Why?

  Looking for answers - replaced a motorized DVI splitter that has worked well for over a year - using HDMI > DVI

  adapter to connect Mac Mini i7 2012, OSX 10.8.5, HDMI port, to the Aluratek DVI splitter.  Configuration below - worked fine for about 2 weeks.  Then came after a few days of inactivity - computer but the display mode 'sleep'... would not wake up. removed the splitter and connected live - monitor (s) work well.   This same issue is why I replaced a divisor of model "TrippLite" - impeccable/no questions for 12 months, and more with this one.    The separator indicates its getting the video signal from the Mac... and video shows displays connected... but see monitors/don't receive it no signal.  I tried to lower the display resolution - no impact.  Have reset NVRAM, SMC several times... reconnected, the range cable several times... tired MiniDisplay Port Adapter > DVI... no luck.  ANY IDEAS MUCH APPRECIATED!  It's in a studio where I need to have dual - in a second workspace - splitter necessary because the distance to the extreme-monitor is too long for a splitter - liabilities

  Technical support said mfgr this Mini graphics card can possibly work for "a while" then stop recognizing the defendant of... How do I?  If we read a single monitor, directly - connected is too much coincidence for a second separator developed the same problem as the other we had - I don't know if there is some thing in the Acer monitor settings that would have an impact on anything whatsoever but I doubt - this new separator 'fixed' the old man a problem after it was connected - and now signal is not recognized through it after a few weeks.

  

  If you have a multimeter, check voltage on his block of POWER & with 2 will check for a ground loop...

• Iphone6 constantly searching for signal

  IVe had my iphone 6 during almost 2 years and recently it just started constantly looking for signal.

  Things I did to try to fix it myself;

  -Reset my phone 10 + times

  -held power and the "home" button to reset 10 + times

  -Reset network settings

  -Went to my service provider and have obtained a new SIM card

  This news is always looking for signal

  -Put my SIM in another phone... I have full signal bars

  ... Is this a hardware problem, the device itself?

  Check if you have completed these steps. If you can not connect to a cellular or cell - data Apple Support Network

  Otherwise, make an appointment at the Genius Bar at the Apple Store nearest to have verified material.

• After updating my iPhone 6 (9.3.4) the WiFi signal becomes very low! I did everything, but the problem does not stop! I don't a not update my other devices & their very good WiFi signals. Please help me solve this terrible problem...

  After updating my iPhone 6 (9.3.4) the WiFi signal becomes very low! I did everything, but the problem does not stop! I don't a not update my other devices & their very good WiFi signals. Please help me solve this terrible problem...

  Here's a tip for the user on the problems of Wi - Fi. Suggest from the top and bottom. Maybe one of them will help you.

  (1) restart you device.

  (2) resetting the network settings: settings > general > reset > reset network settings. Join the network again.

  (3) reboot router/Modem: unplug power for 2 minutes and reconnect. Update the Firmware on the router (support Web site of the manufacturer for a new FW check). Also try different bands (2.4 GHz and 5 GHz) and different bandwidths (recommended for 2.4 to 20 MHz bandwidth). Channels 1, 6 or 11 are recommended for 2.4 band.

  (4) change of Google DNS: settings > Wi - Fi > click the network, delete all the numbers under DNS and enter 8.8.8.8 or otherwise 8.8.4.4

  (5) disable the prioritization of device on the router if this feature is available. Also turn off all apps to VPN and retest the Wi - Fi.

  (6) determine if other wireless network devices work well (other iOS devices, Mac, PC).

  (7) try the device on another network, i.e., neighbors, the public coffee house, etc.

  (8) backup and restore the device using iTunes. Try to restore as New first and test it. If ok try to restore the backup (the backup may be corrupted).

  (9) go to the Apple store for the evaluation of the material. The Wi - Fi chip or the antenna could be faulty.

• New wifi router installed. Why do connect to sites but lose the connection as I browse even though Windows said excellent signal. To deactivate/activate

  New wifi router installed. Because then I can usually connect sites OK but when getting around a site or to another, I lose connection even though Windows said signal is excellent. Toggle heals the problem temporarily. Two tablets under the same roof using wifi even have no problem. There is no consistency in when the problem arises in any session. It happens in Firefox and Thunderbird. Close and restart the program does not help.

  I tried the reset and it was not good. Then I learned that my wife had a similar problem with his ipad I did what I should have done at the beginning, I restarted the router again. Hey presto, problem solved.

  Now, I'm off to eat some humble pie. Thank you, guigs2

• Weak signal with airport Extreme

  Hello, we have an Airport Extreme tour in our condo. The signal is that two of our rooms is low. Is there a way to increase the signal? Not Apple or any other extenders of sale of business or boosters?

  Thank you

  Another extreme airport would be the perfect match to extend the signal of your "main" AirPort Extreme, but an AirPort Express pourrait point be good enough for your application, if the budget is limited.

  Ideally, the second airport would be located in the middle of the area where you need more wireless signal strength and then connect to the 'main' airport using wired Ethernet wired, permanent.

  It is possible to have the second airport to extend the first using a Wi - Fi connection... IF... the second airport is where he can receive a strong signal from the first airport.  A good location is at halfway between 'primary' airport and the area that needs more wireless coverage.

  Remember that when you extend wireless like this, there is always a loss of about half of the potential wireless speed on the network, then the result will be a network with the best range, but reduces the maximum speeds.

  The more you have line of sight between the airports, the network will be operated. Or, another way of saying the same thing, is the 'extension' airport to expand the speed of the signal it receives. It can make the stronger... wireless signal but can't go faster.
