I see where newer Streams use a different chipset, and I also don't know if they cheapened down and added the other antenna or not.I have a DC7700 sff desktop that was running Windows 10 with a small glitch. Due to the age of your laptop, I suspect you only have a single antenna. As far as detecting if you physically have only one antenna, you would have to disassemble the laptop, as no software program that I now of would report that. The improvement in reception will also actually immediately become obvious by looking at the wifi icon in the taskbar. You can also use a terminal based wifi graphical signal strength program called wavemon, and recently I discovered a really nice gui version called LinSSID. You can then use the iwconfig command to look at the signal dBm level with each antenna option to see what works best. You can switch back and forth between ant=1 and ant=2 and ant=0. It doesn't hurt to try and see if you get an improvement, as you can always revert to the previous setting.
However, after selecting the proper antenna port my signal doubled and I went from displaying a couple wifi access points around me to an order of magnitude more. With Linux Mint 18.3 I noticed I could be a room away and still get a connection most of the time, so things got a little better. I forget what version of Linux I had, but I needed to be on top of the router to get a signal, and was forced to apply lwfinger's fix with a USB to Ethernet adapter. I bought my HP Stream in the December of 2015. Kyle_b wrote: "Is there a specific behavior I should look for to see if I need this fix?" (NOTE: the ips=0 command turns off power saving mode, which could turn off the wireless at an inopportune time). Also, unlike lwfingers fix, I notice that it is no longer necessary to reapply the fix after every kerenl update, so that is a huge bonus. Reboot and the new settings should be retained. Parm: ant_sel Set to 1 or 2 to force antenna number (default 0)Ģ) Add the Realtek driver with proper antenna port selected: All that is necessary now is to do the following:įirst check to see if the kernel already includes the antenna select option: It turns out that Lwfinger's Realtek fix is no longer necessary with Linux Mint 18.3 because the antenna select option is included in the latest kernel. I was able to fix the missing antenna issue causing a low wifi signal on the HP Stream 11 with Linux Mint 18.3 after finding a post on a Linux forum.
