I know there's a lot threads about this Realtek rtl8723be wifi card and how it dropping etc. However, I got my card "work" and now I can at least connect to it but that's it pretty much. The connection speed is awful, fast.com shows 700Kbps if I'm lucky. Should be around 10Mbps

I have investigated this around a couple of months and done pretty much all the suggestions what people have suggested around the web. I have downloaded: https://github.com/lwfinger/rtlwifi_new and read https://github.com/lwfinger/rtlwifi_new/issues/28 - which contains a lot of information about this issue including disabling secure boot, windows 10 fast boot etc. etc. etc. etc. and tested the speed with all different rtl8726be options.

So... after months of struggling I would like to ask does somebody, who lives on this planet called Earth, really have Realtek rtl8723be wifi card with a fast connection?

I really hope I'm missing something obvious and could get this work.

EDIT: Rtl8723be WiFi incredibly weak - the question is all about antenna setting, which does not fix my issue. Have already tested the speed with set 1 and 2. Btw, I opened my computer and saw that the wifi card has two antenna wires, what does that mean? I have seen before only one antenna wire inserted into wifi card.

  • @pomsky see my edit Apr 11, 2018 at 7:43
  • So you don't see any change in connectivity/speed after switching antennae? Have you rebooted after changing ant_sel value?

  • @pomsky yes I have, also have tested if there is any difference if I unload and load the card with sudo modprobe -rv rtl8723be and sudo modprobe -v rtl8723be + I have tested by shutting off the computer because on some thread I saw that someone told that only rebooting is not enough. Not sure how solid that information is. Apr 11, 2018 at 7:50
  • @pomsky on my phone fast.com shows 740kbps at the moment and my laptop shows 51Kbps. Apr 11, 2018 at 7:57
