I have a newer laptop that has a wireless card that is apparently not supported well. It is a Realtek RTL8188CE. I had a poor connection via wifi (even when I was only 3 feet away from my router). So, I dug and dug, and found the proprietary driver.
It would not install, so I looked and found the driver which @FreedomBen fixed and put on GitHub (https://github.com/FreedomBen/rtl8188ce-linux-driver). I installed it the first time on the default kernel (LM17), and it worked pretty well. The TX Power was boosted to 33dBm.
I ended up reformatting the machine and installing the 3.16.1-generic kernel to gain some of the benefits. Then I installed @FreedomBen's driver again. It installed fine, however the TX Power was set to 27dBm for some reason.
I tried some different things that I found online (I used all 3 options here: http://www.blackmoreops.com/2013/10/27/ ... h-of-wifi/) and it seemed to set my TX to 30dBm as intented... HOWEVER, I discovered that after a short time (less than a minute), the TX Power returns to 27dBm... Also, the instructions to make the changes apply at boot failed apparently. I checked the power right after startup, and it was at 27dBm.
So my question is How can I set the TX Power of my wireless card to 30dBm at startup? Any and all help would be greatly appreciated! Thanks in advance!

Are you sure you executed the last part of that site too (Setting changes automatically at boot)?

Hi,
first thing would probably to set your country to a less restrictive one like BO.
But I'm a bit surprised at the values, from the manufacturer of the chip I have these values as max (2x because it has a dual antenna)

depending on if you use n or g you would have a max output of 33 or 29, so 27 seems ok if n.I don't see how a software can overcome physical limits.Wi-Fi:802.11b:17 dBm +/-1.5dBm (11Mbps)
802.11g:15dBm +/-1.5dBm (54Mbps)
802.11n: 13dBm+/-1.5dBm (HT20 MCS7)

Yeah, I'm not too sure how it did, but I was definitely at 33 before. And it stayed at 33 for the entire time. So Idk. I just need a way to boost my connection until I can get comcast to send me a new router...

Okay. I will do this as soon as I get home. I'm at work at the moment. Thank you Pat!
