    AC-7265 Frequent disconnects/Painfully slow when connected

    JTLee9153

      Hello all,

      I've had my new laptop for about 2 months now, and there has been a wifi problem since day 1. My laptop is running Windows 8.1 with Intel DualBand Wireless AC7265.

      Here are the list of problems that I've encountered.

      1. I would have 5 bars showing on the taskbar, but the internet is painfully slow.
      2. It also just drops connection if I open 2 or more tabs with images in them, as if it can't take it and just decides to stop trying. None of my other computers, including a mid-2009 macbook pro, is having this kind of problem as they run completely fine, fast and reliable.

      I don't have these problems at my apartment, with the following conditions:

      1. The router is basically 15 feet away from the laptop with no walls between the laptop and the router.
      2. Comcast modem that doubles as a wireless router.

      I have problems in my actual house, where:

      1. The router is further away with walls between the laptop and the router. However, moving my laptop to 5 ft away from the router with no occlusion did not fix anything.
      2. Comcast modem that requires a separate wireless router (Belkin AC1200 Dual Band AC+).

      Any advice is greatly appreciated. Thanks.

          Hello JTLee9153,

           

          If you bought this computer with the Intel® Dual Band Wireless-AC 7265 already installed in it, the first recommendation would be to check with the OEM (Original Equipment Manufacturer) for the latest drivers and then test the connection. Once you have done that and you notice the issue persists, we recommend that you access this link that my help you as well to have this issue resolved.

          Intel® Wi-Fi Products — TechNote: Access Point Interoperability Issue with uAPSD

           

          Regarding the frequent disconnection, this is what you do:

          1 - turning off the power saving related functions can prevent unexpected disconnecting, sudden connections speed drops and the adapter working at its maximum performance. Go to control panel >>> Hardware and Sound >>> Power Options >>> Set the High Performance and apply the default settings. (Check the Change Plan Settings >>> Change Advanced Power Settings >>> Wireless Adapter >>> Power Saving Mode and make sure both On battery and Plugged in are set to Maximum performance).

           

          2 - Set the advance settings of the Intel® Dual Band Wireless-AC 7265:

          - Right click on Windows Icon and choose Device manager >>> Network Adapters >>> Intel® Dual Band Wireless-AC 7265 and right click and select Properties.

          • Select Advanced page to set the value of u-SPDA support to disabled.
          • Check value of transmit power and make sure it is set to 5. Highest.

           

          *Very Important: It's recommended to use 2.4HGz band for better penetration capabilities which improves the connection signal if there are walls or other solid objects blocking between the router and your laptop. Next, change the Intel® Dual Band Wireless-AC 7265 advanced settings in order to match the settings with the router.

          • Set the Wireless Mode, example : 802.11 a/b/g/n according to the support mode of your router.

          • Set the preferred band to Prefer 2.4GHz band (considering the obstacles such as walls... etc.)
          • Set the HT Mode for 802.11n compatibility. (VHT Mode is for 802.11ac compatibility).

          • Set the 802.11n Channel Width for 2.4GHz to limited 20MHz. This one has smaller bandwidth than 40MHz, but it has better penetration capabilities which improves the connection signal.

          Furthermore, if there no Bluetooth devices to be connected to your computer, turn it off because the wireless and Bluetooth* combo share the same wireless connection and antenna so turning off the Bluetooth can let the wireless connection has the entire usage of bandwidth and the antenna. Also, by turning off the Bluetooth*, it will help to decrease the signal interference since Bluetooth devices uses the same band.

          Lastly, setup these two properties as shown below can improve the quality of the wireless connection.

          • Set the value of Roaming Aggressiveness to Lowest.
          • Set the value of Ad Hoc QoS Mode to WMM disabled.

          We do hope this helps you to resolve this issue.

            None of this works.  I have all of this done with the newest 18.12.03 drivers dated 7/16/2015 and the performance is abysmal.  I can be 5 feet from my Netgear Nighthawk AC router and only get 54mbps.  Then I pull out my LG G3 phone basically anywhere in my house and I have 800+ mbps.  This is honestly one of the most disappointing wireless cards I've ever had in my life.  There are people in the intel forums saying intel should be sued. 

             

            It feels like everyone in the world except Intel is aware that this chipset either has subpar hardware or drivers.

              OMG, ditto, none of all their advices work at all and i just got aorus laptop and that came with that driver and oh my god! the wifi only works when i am near the router but doesnt work in my room.... on other devices in other rooms i get 72 mbps and on this laptop i get 2-5 mbps but near the router it works perfectly. A brick wall or something really prevents it from getting the download speed even though the signal bars are full. I think the solution would be to get rid of this driver and get an older version because all my other devices much further away are working perfectly and are running older drivers like 6000 series and this is a pain.

               

              Let me see if that solution i proposed works or not...

                I have another interesting issue - my AC7265 is connected with my router with 866Mbps while the maximum transmission speed with my NAS ~ 200mbps\

                Strangely but Macbook Pro achieves 600Mbps

                 

                Does it mean Intel wireless is ### or something is wrong with the config? Any advice?

                  Try and test your laptop with 7265 near the router and ser if it is getting full speed because i think the problem with it is that it has very weak signals so the download speed lessens with distancr so try and test with a very close range

                    This was my initial test - but it doesn't help, signal is full bars

                    As mentioned, Macbook is connected to the same 5Ghz network with same Mbps speed and achieving 600Mbps transfer  so definitely an issue with Intel...

                      i have changed 2 aorus laptops because of this internet issue and they say that there is no fault with the computer whatsoever but i said that i am getting crap internet on this and i am on my third laptop. I had to get powerline adapters because i think that the problem is with the adapter and when cabled it gives full speed so nothing wrong with the device or anything but this stupid 7265 driver sux and yeah it is an intel issue with this driver and many people have reported already which you can verify by surfing on other forums. try forgetting the internet and test again near the router but it will not achieve full speed llike i never get full speed unlike my 3 years old devices which work perfectly

                        This thing is a piece of junk, my LG G3 gets a faster connection to the router and the antenna is probably 1/10th the size.

                         

                        I have the newest newest driver and it is still stuck at 54mbps stated and probably 15mbps actual since i can't seem to download faster than 1.5MB/s

                         

                        I really hope broadcom comes along with a NGFF card and eats intel's lunch.

                          so is there any alternative to AC7265? anything?

                            It depends on which form factor you have.  If you have the mpcie you can buy an Azurewave AW-CE123H, if you have the m.2 ngff card there is no real alternative because there was only a limited run of broadcom cards and they're $160 on ebay if you can even find one.

                                Hi all, I tried setting the Wireless Mode to 802.11g and that solved my issue. It had issue with my TP-Link Archer D9 with 802.11a/b/g. Hope this help someone. Using Acer Travelmate P645.

                                  Update:

                                  Killer Wireless AC 1535 - Awesome adapter, works very well with strong throughput at range and no dropouts. (does not support channel 12,13)

                                  8260NGW - Have not tried yet.

                                  Broadcom BCM94352Z - Tried, not that impressed, worked ok, did not drop out, better impressed by the Killer 1535. (Did not support channel 12, 13)

                                    If you're using a bluetooth device, I think it's the fact that the adapter is trying to handle both bluetooth and the wifi connection - and as far as I can tell, it can't.

                                     

                                    I tested my download speed using my bluetooth mouse and it was 4.85mbps download, and 1.54mbps upload.

                                     

                                    Then I turned off the bluetooth mouse and plugged in a wired mouse and it went to 20.83mbps download, and 2.63mbps upload.

                                     

                                    After switching to the wired mouse I first tried setting "Wireless Mode" to 802.11 g as suggested above. It topped out at around 15.5mbps download speed.

                                     

                                    Then I switched "Wireless Mode" back to 802.11 a/b/g and got the higher 20.83mbps speed.

                                     

                                    This totally sucks because I bought an ASUS UX501 laptop in late January 2016 partially because I could conserve my USB connections by using a bluetooth mouse. Obviously this wifi adapter is not currently capable of handling both wifi and bluetooth in my computer. I'll keep checking for future firmware updates and hope they solve the problem.

                                     

                                    It is nice, however, to suddenly have my internet speed back.
