Using Realtek 8732be on a HP Stream 11 is extremely slow

I have looked at the results of your wireless script.

You have two error messages. Error: nmcli (1.2.0) and NetworkManager (1.1.93) versions don't match. Force execution using --nocheck, but the results are unpredictable. This has been reported as bug 1590335 by another user, but a reboot fixed it for them.

[24359.876232] usb 1-2.1: firmware version 0x4330 and device bootcode version 0x4802 differ
[24359.919778] zd1211rw 1-2.1:1.0: firmware version 4605.

This appears to show the incorrect firmware is being loaded onto a USB wireless device.

However your actual problem appears to be Realtek Wifi Card RTL8723be Not Working Properly. Follow the steps given in the solution there.

If this solves your problem please click on the tick mark on the left to show your problem is solved. If not repost the output of the wifi script, preferably after resolving the other two errors. The first should dissapear after a reboot. The second wont appear if you remove the USB device before running the script.

I have looked at the results of your second run of the wireless script. Lets look at a few fragments:

    UP BROADCAST RUNNING MULTICAST  MTU:1500  Metric:1
      RX packets:700903 errors:0 dropped:0 overruns:0 frame:0
      TX packets:388503 errors:0 dropped:0 overruns:0 carrier:0

      RX bytes:956196276 (956.1 MB)  TX bytes:35329540 (35.3 MB)

This shows a wireless connection working perfectly and receiving nearly a gigabyte of data. The next fragment

      Rx invalid nwid:0  Rx invalid crypt:0  Rx invalid frag:0
      Tx excessive retries:10090  Invalid misc:95221   Missed beacon:0

Shows that the wireless adaptor is performing under difficult circumstances. It is as if it is being jammed.

This shows the jamming is coming from an access point called HP-print-C3-Deskjet 2540 series. I would suggest changing the RF channel of either the access point or the printer so they are on different channels. At the moment they are both on channel 1. The only other channels being used are 6 and 7 so you have plenty to choose from.

The printer is acting as an access point because you have pressed the wireless direct button (see page 53 of the user manual). You should have connected your printer to your router following the instructions on page 49 of the manual. The user manual is available online here

I have a brand new HP Stream 11-r001nd. I am able to connect to my network, but it is too slow. Even when I put my laptop and the router right next to each other it's too slow to watch a youtube video (if the webpage from youtube does load at all). On Windows 10 this problem didn't exist.

In this youtube video it shows that using version 14.10 the speed was acceptable. But that version is not supported anymore.

Please run the ubuntu forums wireless script (github.com/UbuntuForums/wireless-info) and paste the results into paste.ubuntu.com then edit your question to include a link to it

I've pasted the outcome of the script in the link paste ubuntu above

I tried both, but I didn't succeed... still not working. Do you think after all these tries, I should run the script from steve Roome again?

I've run the wireless script from ubuntu forums again becouse I can't see any connections anymore from my internal wifi card, after all my tries to fix it. This is the new outcome of it: paste.ubuntu.com/18377793

Please give more detail about what you tried and what the results were.

I definitely can't reconstruct everything I did, but I can log it from now on. I tried your solution, pilot6's solution, and today I found this (ubuntuforums.org/showthread.php?t=2261702) on the ubuntu forums, and tried all the sugested solutions in the thread. As far as I remember did all the scripts do a lot without rumbling error or fatal in between all the abracadabra, and some did even say succeed at the end. Nevertheless, it's still not working. I also have no clue how to give you more detail of the current situation.

By the way, that printer access is becouse it is connected to my home network to be able to print from every device.
Thijs almost 8 years

How can I change the channel of that printer? becouse if it can speed up my connection... that would be great. (the first time I came back to my question, I was just too excited that the onboard wifi connection worked, even better than my extended usb wifi adapter, so I didn't look any further)

After I totaly ruined my ubuntu installation by trying out lubuntu and xubuntu layers on top of my ubuntu layer, I had to redo the process. And I can now tell for sure that the given solution at the other thread (askubuntu.com/questions/717685/…) did solve the problem. I did try it on a fresh installation, and it worked perfectly fine!
