• 5 GHz WiFi on E2500 has stopped working

  I had my E2500 with 2.4 and 5 Ghz WiFis with different names, works very well for months until yesterday 5 GHz WiFi stop working and I got my PC back to 2.4 ghz. When I go to the page of the router-> status-> wireless networks in the 5 GHz network shows an empty address, channel by n/a and the width of the channel by n/a, while 2.4 has fill out them correctly. I tried using different settings for WiFi, but nothing has worked. I also tried resetting the device and update the firmware. How can I know that the 5 GHz interface is not faulty and the cause of the problem?

  I found a solution to my problem: I came back the firmware to the previous version (I had upgraded to the latest version 2.0 front) and now the radio works fine. It seems that the firmware has not been properly tested.

  Thanks for your help!

• Can't see the devices connected to 2.4 GHz WiFi

  I recently bought and set up a R6220-100NAS Netgear with the 2.4 GHz and 5 GHz WiFi signals available less than a month ago and updated to the latest firmware, when I ran my initial installation (although I don't know which version it is). I have 1 PC connected to my router and other devices (including my printer) are connected wireless.

  Since the installation of this new router, I noticed that I cannot print on my Canon PIXMA MX892. I was not able to solve this problem, as much as I would like, but so far, I've been able to determine that the printer is only able to connect to my network of 2.4 GHz, and I can't ping from my PC (ping to the IP address response comes back under the name of "unreachable" as opposed to the typical error "request Ping" can't find host).

  I tried ping my Smartphone when it is connected to the 5 GHz WiFi band and had no problems. When I spent my smart phone to the band of 2.4 GHz and ping its IP once again, I got the same message "inaccessible".

  Some tips on how I can still fix this and restore my print capabilities?

  Problem solved. I did a factory reset on the router (and manual reconfiguration) and I can now print and ping on two WiFi networks devices successfully. Looking at the configuration settings that I saved before the reset, it looks like isolation wireless has been activated for the 2.4 GHz WiFi network. It was set to '1' in the .cfg file.

  It was my suspicion from the beginning, but I couldn't find the setting in the router installation options.

  • I have the latest Windows 7 drivers for the WIRELESS card
  • The button on the front that enables / disables wifi and bluetooth is turned ON

  Also, I have a Dual Boot on the laptop with Ubuntu 10.10, and the problem also happens, so this is not a configuration / drivers problem.
  The strange thing is that the adapter appears in windows 7 (the device administrator) and Linux (lspci)

  I also checked the location Mini PCIe where the WIFI adapter is plugged in and it seems to be OK...

  So what the f * k that happens?

  I would be grateful any advice!

  I have fixed the CMOS of compensation.

  Thnaks.

• Accidentally changed wifi band setting, the wireless doesn't work anymore

  Hello

  So, we just installed a new router and everything was fine.  I had the idea in my head to change the band from 2.4 to 5, then find that my wireless adapter does not support 5.  Thus, the wifi does not work (even if it recognizes the my network shows 4-5 bar signal).  Normally, I would go back and change the setting, but I can't find it anywhere.

  I tried a system restore, but also by browsing my Advanced settings on the card itself, which doesn't seem to have something out there on the change of the band.

  The network adapter is a intel centrio (r) Wireless - N 2230.

  Intel website was completely useless, and their tech support does not meet the phone on weekends.  I'm 99% sure that changing this setting will fix the problem, but I can't.  Help, please!

  This can help

  Wireless card installed: (1 x 1) 802.11b/g/n and Bluetooth® 4.0 combo

  Hey guys!  I recently bought this laptop new. Wifi is always low enough on her because she has a 2.4 GHz adapter installed.  I want to upgrade the wifi card inside a wifi 5 GHz with the bluetooth combo card.

  Which adapter is compatible to safe installation for 5 GHz wifi + Bluetooth combo for my model? Help!

  Speed, according to Intel, 2 x 2 AC 7265 could reach the theoretical limit of 867 Mbps, while the AC 3165 1 x 1 433 Mbps

• Pavilion 17-ab077nz: 5 GHz WiFi only?

  New laptops (sold in Switzerland, insofar as this matter) speak 5 GHz WiFi only? I'm looking for a new laptop. Half a year ago I saw an ENVY 17-r187nz with 802.11a/b/g/n/ac, but now the specification of a 17-ab077nz Pavilion (which is otherwise almost identical) talking only about 802.11 ac.  Other new models also offer 802.11ac only. No more recent laptops provide is more possibilities Wifi 2.4 GHz? Having high speed at home is great, but I fear that, on a trip, 5 GHz networks will not be not always available.

  802.11ac works that in the band 5 ghz but 802.11ac compatible radios will return to 802.11n and if 2.4 ghz 5 ghz is not available.

  http://www.Trustedreviews.com/opinions/802-11AC-vs-802-11n-what-s-the-difference

  I've owned several 802.11ac laptops and never had a problem connecting at airports, Starbucks, etc. And they tend to be broadcast only on the band 2.4 ghz or 2.4 and 5 ghz.

• 5 GHz WiFi card update - Compaq Presario

  I just got a new router today and found out that it is a double router broadband and supports the 2.4 GHz and 5 GHz. I was wondering if I could update my existing WiFi card that supports only the 2.4 GHz and get one that will take in charge the 5 GHz band. Also if I have a 5 GHz WiFi card in my laptop can still connect to networks that support 2.4 GHz only? How much would cost a new card? And finally, if I can improve my card, how I put in my laptop?

  Data sheet:

  Model: Compaq Presario CQ57-33WM

  OS: upgrade to Windows 8.1 Pro

  Memory: Updated 6 GB of RAM

  Hard drive: 320 GB 5400 RPM

  Processor: FSB of 1333 MHz 1.50 GHz Intel Celeron processor B800

  Network cards:

  Realtek RTL8188CE 802.11 b/g/n WiFi Adapter

  Realtek PCIe FE Family Controller

  (A lot of WAN Miniports is also listed in Device Manager)

  Can I still switch my wireless card based on these specifications? It would be difficult to change? Let me know if you need more information on the computer.

  Also, if it ends up that I can't change my card or it is really hard to change, could use something like this as a last resort? Double USB adapter wireless broadband

  Any help is appreciated!

  Thank you!

  Hello

  According to the service manual this lappy does not support 5 GHz wireless cards. Most recent computers based Intel Mobile (Ivy Bridge and higher) support the latest maps wireless Intel including the last 7260AC one. Your laptop is older, so I can't say with certainty what will work or not. In this case I suggest to get some usb adapters wireless such as that of your link or one of them:

• 5 GHz Wifi unstable

  I recently bought a HP 15 Omen, running Windows 8.  Everything was fine until two days ago, when my 5 GHz wifi disappeared (I can always connect to the 2.4 GHz network, but it is considerably slower).  After Googling for answers, I went into

  Device management->

  Network cards->

  Intel (r) Dual Band Wireless-AC 7260->

  Properties.

  In properties, advanced, I changed the value of 802.11n for 5.2 GHz channel width... from Auto to 20 MHz only.

  So he resolved the problem, for about 30 minutes, then the 5 GHz network have abandoned once again and then reappeared after a few seconds.  And now it disappears at random, usually around five to six times a day.

  It is not a major problem that I can work around it, but it becomes a big trouble.  I would be grateful for any help anyone can give.

  The 5 GHz channel has a range that is much shorter than the 2.4 GHz due to its higher frequency channel. When your network is de-energized, you may even be unable to reconnect.

  To isolate the problem, you can check if another device of 5 GHz is the same problem as your PC. If Yes, then you need to downgrade to 2.4 GHz channel, or consider expanding your signal with a Repeater.

• iPad Mini location Service no longer works

  Last month, I've updated my Mini iPad for iOS 7.1 to 9.3.2 just to play PokeGO (the first time after 2 1/2 years of use without updating my iPad). After the update, the location of Services/GPS works fine on Apple and Google Maps maps with no signs of problems, I could even enter the game PokeGO (even if the game is buggy mess from the start).

  But one day when 9.3.3 update went live, he always ask me to update my iPad, but when I tried to open all cards, the location of GPS and Services no longer works. I tried to reset the router, turning the deactivation/activation of location Services, and then reset network settings and location on my iPad, but still not solved.

  And just recently I've updated my iPad to 9.3.4 because my theory is that the location/GPS will not work without having to install the last update, but I gave up that my iPad is already bricked because the location Services and applications required GPS are now rendered useless.

  Your iPad mini is a cell with GPS model if it is not the case, your location is only estimated from IP addresses and WiFi. That said, you should check the settings for applications, in order to ensure that access to the site is enabled. And if this is the case, turn it and turn it back on for each of them. You did such a big jump in versions of iOS it is difficult to know what security changes have been made. You should probably reconsider all your settings, as if it were a new configuration. Also, make sure that your applications are all updated.

• Apple TV 4 suddenly no longer works

  Since last week my Apple TV 4 suddenly no longer works, bought 27 December 2015.

  I already have things:

  1 charge of the remote control

  2 disconnected and reconnected the power cable, hdmi and ethernet (my wifi is unstable when I'm apple tv). After re - all of these cables, the device flashes 7 times and then shortly made a break.

  3. use a different power cable.

  4 searched on the internet on the significance of the 7 blinks, found nothing. Which for me is odd, blink-sequences usually have a meaning.

  5 purchased and attached a USB C cable to my iMac will hopefully restore via iTunes. But he does not appear in iTunes (updated).

  6a tried to put it into DFU mode by connecting the apple tv with the usb cable and pushed the home (tv) button and the button play-pauzé for 6 seconds. I was informed that the unit should Flash and then iTunes should recognize it.

  7 has tried to pair the remote control again, in case there's an accident and repeated all steps.

  8 has obtained information that the cable I use is supposed to be good.

  These steps did nothing, the only thing that happened between the last time that I used it and when I realized it has no function, is that they have replaced my for a "smart" electricity meter But I can't be sure that this caused all this 100%. The appliance was not turned on for the replacement.

  I see no option to manually search for the device connected to my iMac, and no indication that iTunes gets even a hint of a connection.

  Thanks in advance.

  It has a 12 month warranty - contact Apple or take it to an Apple store and ask for a replacement/repair.

  You talk as if you have tried all reasonable measures including the verification of the cable USB is correctly (no ony supply).
