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.

  • 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.

  • can it work on wifi only

    IM considering getting a Apple Watch, but I was just wondering if it would be able to use apps like Instagram without my phone nearby and wifi only (that my phone is connected to front)?

    Also I don't know if wait for 2nd generation going, could anyone give advise?

    Thanks, Justin

    Hello

    A Wi - Fi connection does not work as a substitute equivalent / like-for-like for the Bluetooth connection.

    Apple Watch offers a number of features when the pair iPhone is not connected via Bluetooth:

    -Play music from a playlist synchronized on Apple Watch.

    -Use the watch for the time, as well as alarms, stopwatches and the clock.

    -Keep track of your activity (Stand, Move, exercise) with the application of the activity.

    -Follow the training with the application of the workout.

    -View photos of the synced photo album.

    -Use Apple pay for shopping.

    If your Apple Watch is within range of a wireless (2.4 GHz) network that your iPhone is connected to before, but your iPhone and watch are not currently connected via Bluetooth, the watch can connect to the network and you can also still:

    -Send and receive messages using iMessage.

    -Send and receive digital messages Touch.

    -Use Siri.

    -Make and receive calls if you have calls enabled Wi - Fi (depending on your operator).

  • Apple TV (4th gen) faster with 5 GHz WiFi with the ethernet cable

    When my Apple TV is connected to my network via 5 GHz WiFi it gives me a faster speed (about 120 Mbps) connections it makes when I plugged it on my network (about 45 Mbps) ethernet cable.  Why is this?  I thought that the ethernet would give me the fastest connection possible.

    The ethernet port on all ATVS (including the 4th generation) is only 100 Mbit/s. The actual speed depends on the quality of your network as the routers, switches and cables components and of course it depends on the length of your ethernet cable and if it is damaged in any way (folded or crushed). And finally, that depends on how fast you have actually measured, on your local network speed, or speed on your WAN.

    Hi all

    I have HP ENVY 4 1043cl model which has wifi Intel Centrino 2230. According to the maintanance user guide - this laptop supports only 2.4 Ghz wifi.

    I could replace my card by another wireless (which is not leasted in the user guide) that supports wifi 5 ghz? For example, Intel® Centrino® Advanced - N 6235 Wi - Fi and Bluetooth?

  • 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.

    Hello

    Just today, I noticed that my iPhone 6s was download continuously at the speed of the network via WiFi only when is plugged in the wall charger or the USB loader on the computer. As soon as I stop charging the phone, the download stops. I have no idea what download and I'm a little frustrated because my connection high speed/wireless home is capped.

    Sync to iTunes on WiFi and iCloud backups are disabled. I had subscribed to 9.3.2 iOS beta on the registration by registering with my Apple ID last week, but I haven't added the certificate so that it can download OTA or via iTunes. I have no update available on my Apple store as well.

    I noticed the slowdown on my cause of internet connection of desktop computers that my phone of summer download something on wifi while he is in charge and I also saw the use of the network by using "System Monitor" app on the App store.

    Kindly help me to solve this problem.

    Thank you

    I did a factory reset on by phone by "Erase all content and data" and chose to set up as a "new iPhone" after reset done. There are now only apple applications on the phone, I connected to wifi with the charger plugged and the problem persists. I wonder if it was to be an apple iOS update, I am on iOS 9.3.1 and 9.3.2 is still in beta, I'm not sure if there is an apple update going on in the background.

    Kindly help.

  • L50-B-1NM satellite - wifi only works near the router

    Hi just bought this laptop for my daughter Toshiba L50-B-1NM 15.6 inches processor Ci3 4 GB 1 TB and wifi only works if he was sitting next to the router.

    It will connect to the internet if the ethernet cable is connected, BUT for wifi, the laptop has been sitting almost touch the router. The rest of the House works well.

    Please could you help me before I take it back to the shop and eventually making a fool of myself.

    I'm really not good with technology so if you do not answer could you explain to me like a baby please ;) lol

    Thank you very much, totally disappointed at the moment because it cost me a lot of money for it :(

    Hi maria,

    I think you should consider a fact: the L50-B-1NM Satellite was equipped with an Intel 802.11ac + card agn combo Wifi/BT.

    802.11 AC is a new WLan standard that isn't taken care of by all old WLan routers.
    But of course, the standard 802.11 A / G or N must be supported by older devices correctly.

    I think first of all you must check if the wireless performance question isn't related to energy saving settings. I guess during wifi problems, the laptop uses battery power
    In this case we would use different power plan settings.

    Please check the settings that are in the advanced within the current energy saving Central WLan power settings.

    Where this doesn t help you solve the problem of WiFi signal weak, you should contact the authorized Toshiba maintainer to check the connection to the WLan antenna.

    It may be possible that the antenna isn't properly connected, which is originally a weak WiFi signal.

    Because the laptop is under warranty, it should be fix toll-free number.

  • I ordered a 3 wifi only iPad and they sent me a wifi + 3g by mistake without sim card

    I ordered a refurbished iPad 3 wifi only and they sent me a wifi + 3g - mistakenly - without sim card.  This is my first experience with a tablet of any kind and so I have a few questions:

    1. is there a reason I can't return the wifi + 3 g iPad for iPad wifi only?

    2. What is the difference between an iPad only wifi and the other with wifi + 3 g without a sim card?

    3. it would be an advantage to get a SIM for iPad?

    4. what could I do with wifi + iPad 3 g WITHOUT sim card that I can't do with the wifi only?

    Thanks - TP

    1 honesty

    2 WiFi + cell phone has GPS receiver and cellular material (obviously) to work with the cellular network.

    3. Yes, but you're dishonest.

    4. you can have internet access while you travel (for example: in your car, on the beach etc, where there is cellular signal coverage)

    I understand it's not your fault, but you should always contact the seller and inform them of the error. If they tell you to keep, jump up and down with happiness.
