Good afternoon. Yesterday I installed F20 in a toshiba laptop. But internet is very slow, its highest peak is about 150-200 Kbps, but the goes all the way down to 200-500 bits per s, and then goes up to 50 or 70 Kbps, and then again down. In Windows internet is OK, but not here. I haven't tried connecting through ethernet. Normal internet speed should be about 620 Kbps at peak. Network controller: Realtek Semiconductor Co., Ltd. RTL8188EE Wireless Network Adapter (rev 01)

EDIT: I also tested my speed in an online tester, but results are normal, it reach its highest speed, the same result as in windows, but pages are loading slow sometimes, sometimes load normal, youtube videos load slow and pause too much for buffering, torrent and downloads reach up to 200 KBps and then drop to say 1KBps or half a KBps, please hel!

EDIT 2: It seems to be something related to the updated kernel. Internet works fine with 3.11.10, but all of the above problems are with kernel 3.15.6

Try kernel 3.14

If the experience is persistent (not a temporary problem), there might be actually a bug in the latest kernel. It is helpful to check dmesg output for errors with regard to WiFi. You might also run journalctl -lf in a terminal window, then keep your normal browsing activities. When you felt a sudden drop in speed, check the window to see if there are error messages in it.

Finally, you can try some intermediate kernel versions (e.g. 3.14.X, 3.13.X) to see in which version the problem started to appear. It would help debugging the problem. But do the log checking first.

I have had the same problem (also a Toshiba with the RTL8188EE and Fedora 20 ) ever since 3.15. I have tried each new kernel as it has appeared in the repository to no avail, so I just boot back into 3.14.9. This was the last version of the kernel where I had no problems with regard to wireless stability/speed.

This seems to be a kernel issue and the only solution appears to be to wait for it to be corrected at that level. See a thread on this at

UPDATE: There was a bug filed at . Instructions can be found in the comments there on how to install the new realtek driver. I have just done so on the 3.15.10 kernel, and it works fine so far.

It might be better if you report a bug for it at redhat bugzilla too.
