I still have the original problem I reported: Wifi works fine with original HP set up of computer but will not work if I try to install any other Debian/Ubuntu based OS or update Ubuntu to latest version. HP have obviously tweaked the installed version somehow to make it work. A Puppy Linux derivative worked as did Console Linux but they are the only ones I have found so far.

My 2 cents on this dreaded wifi+bt card. My system: Lenovo Flex 2 - intel i5 + 8GB RAM Ubuntu version: 15.04 (clean install) Previously when I was on 14.04 LTS, I had to create a rtl8723be.conf file and add the options to make my system stable. I did a clean install of UBuntu 15.04 a couple of days back. After which, I am able to connect to the wifi network without any extra setting. I made a few changes to wifi router though (Dlink N router) 1. Set channel to 1 2. Set frequency to 2.4GHZ 3. Set encryption to WPA+AES I have a stable connection, with no drops . I have a few issues though. 1. The wifi never connects when laptop is woken up ffrom sleep. Needs a reboot 2.

Fortunately, the modified driver also loads fine after rebooting. And it connects to my company WiFi. But besides than that, the driver doesn't bring any improvement. So WiFi still hangs and the system still crashes after module unload + reload. The crash is even at the same code position: halbtc_get_rfreg+0x23/0x30 [btcoexist] Of course, the exact binary address is different, as the RTL modules from the DKMS are of different size, so loaded to different physical addresses. But the crash still appears at the beginning of the function halbtc_get_rfreg in the module btcoexist. As "btcoexist" probably means "Bluetooth Co-Exist", I experimented with turning bluetooth completely off via: rfkill service bluetooth stop rmmod everything, that looked like bluetooth After that, the system no longer crashes after unload and reinsert of the rtl8723be module. So the crash (which still needs to be fixed!) and the WiFi getting stuck might be unrelated. I did a few more experiments with the "new" driver from post #20 with different access points: * Connect to a FritzBox 7490 works * Data transfer to that FritzBox fails from the very beginning, though. Not even a ping goes through. It is the uplink (from the card to the router), that is stuck. On the downlink, I can see broadcast packets coming through. * Tethering with Moto X (2nd gen.) completely fails. It doesn't even see the Moto X2. This is weird, because with the stock driver of the stock kernel of Ubuntu Vivid, that tethering works at least in the beginning (until the connection gets blocked). * After changing the broadcast channel in the X2 to 5 GHz then back to 2.4 GHz, it now sees the X2. Downlink and uplink speed are fine. * Tethering with a Nokia 820 works, too. I could even got a remarkable number of 50 MBit/s for downlink speed, despite that the W-LAN connection lists 72.2 MBit/s as max. speed.

@petzke I've tried all different driver options on my Yoga 2 13. Although wifi stability improved, I was never able to achieve fully reliable connection at all times. I've switched to an Intel ac wifi card recently, and wifi is much better now (although still not 100% reliable, but that's another driver's problem). I had problems with suspend-to-ram too, but the situation has improved: I'd praise kernel updates for this improvement.

[Bug 1461174] Re: Realtek Wifi card rtl8723be [10ec:b723] WiFi has an issue
Just a short note: I have problems, too, with this card on Vivid. Usually, in less than one hour after going online the connection just gets stuck. Sometimes, the connection recovers after a few seconds or minutes, and data flows again. Sometimes it doesn't until the wireless is switched off and on, or the machine is rebooted. The behaviour is very erratic and random. When the connection is stuck, turning the wireless off via kubuntu's NetworkManager graphical client takes quite some time (10 seconds or so). Fortunately, loading the driver with the option fwlps=0 solved the issue for me! Since I wrote the line: options rtl8723be fwlps=0 into the file /etc/modprobe.d/rtl8723be.conf , I've had 36 hours of trouble-free wireless experience. As it was hard to survive 36 minutes online before without that line, this is already a great improvement for me! Apart from the unstable WiFi, I was also fighting with unstable suspend- to-RAM on my Laptop (Lenovo Yoga 2 with 13 inch screen). Once in a while, the computer would just crash or hang, when turned to suspend-to- RAM by closing the display. In that state it still consumes battery, so the CPU is not turned off correctly then. When re-opened later, the display stays dark. That problem has also disappeared since I added the beforementioned option to the rtl8732be driver. So I assume from my observations, that with fwlps=1 (the default), the driver or the card or both after some time get into an inconsistent state with the following symptoms: A) No more packets are received and/or transmitted B) Turning off the wireless LAN and unloading the driver takes a rather long time (a few seconds instead of a fraction of a second) C) suspend-to-RAM crashes or fails, and leaves the laptop in an unusable state (display off) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1461174 Title: Realtek Wifi card rtl8723be [10ec:b723] WiFi has an issue To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1461174/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Realtek wifi adapter has bad compatibility, different hardware revisions might need different driver config. All we could do now is rebase to the latest on every new release, backporting is not safe.

Verified with the DKMS provided in comment #20, it looks good! tested with the "mtr ubuntu.com" command, with ~24500 packet sent, loss rate ~0.0% Thanks. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1461174 Title: Realtek Wifi card rtl8723be [10ec:b723] WiFi has an issue To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1461174/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
Re: [Bug 1461174] Re: Realtek Wifi card rtl8723be [10ec:b723] WiFi has an issue
Hi I did look into the bios to see that everything that might stop the adapters working was enabled. As regards bios update when I visited HP's support site no bios seemed available for an Ubuntu machine. There were downloads for win 7, xp, vista etc. Perhaps this machine works better with this older bios ?

Hi, as this bug is affecting many different platforms, I don't think it's a BIOS issue. Verified on 201403-14879 - HP 355 G2 Notebook PC, with 14.04.2 stock image installed The RTL8723BE wireless card is very unstable, it can connect to the Internet at the very beginning. But stop working after a few minutes (still connected), the "mtr ubuntu.com" command shows the packet loss rate is over 90% in 4000 packets. ** Tags added: blocks-hwcert ** Also affects: hwe-next Importance: Undecided Status: New ** Changed in: linux (Ubuntu) Status: Incomplete => Confirmed ** Tags added: 201403-14879 -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1461174 Title: Realtek Wifi card rtl8723be [10ec:b723] WiFi has an issue To manage notifications about this bug go to: https://bugs.launchpad.net/hwe-next/+bug/1461174/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
