Very slow internet rtl8192ce

Hi there,

I have one of these:

04:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter (rev 01)

and I've recently been experiencing very slow internet on my PC. I don't know whether it's related to a recent kernel upgrade or not:

[mike@mike-pc ~]$ uname -a
Linux mike-pc 3.19.3-3-ARCH #1 SMP PREEMPT Wed Apr 8 14:10:00 CEST 2015 x86_64 GNU/Linux

I have tried unsetting the fwlps and ips options on the module, and it is now set like this:

[mike@mike-pc ~]$ !50
systool -v -m rtl8192ce
Module = "rtl8192ce"

  Attributes:
    coresize            = "56303"
    initsize            = "0"
    initstate           = "live"
    refcnt              = "0"
    taint               = ""
    uevent              = <store method only>

  Parameters:
    debug               = "0"
    fwlps               = "N"
    ips                 = "N"
    swenc               = "N"
    swlps               = "N"

  Sections:
    .bss                = "0xffffffffa04ced98"
    .data               = "0xffffffffa04cc000"
    .exit.text          = "0xffffffffa04ca0ea"
    .gnu.linkonce.this_module= "0xffffffffa04ceb40"
    .init.text          = "0xffffffffa04d1000"
    .note.gnu.build-id  = "0xffffffffa04cb000"
    .parainstructions   = "0xffffffffa04cb978"
    .rodata             = "0xffffffffa04cb040"
    .rodata.str1.1      = "0xffffffffa04cba40"
    .rodata.str1.8      = "0xffffffffa04cb9a8"
    .strtab             = "0xffffffffa04d3530"
    .symtab             = "0xffffffffa04d2000"
    .text               = "0xffffffffa04c2000"
    __mcount_loc        = "0xffffffffa04cb7a0"
    __param             = "0xffffffffa04cbaa0"

Other computers/devices on my network are seeing much higher network speeds (15Mbps+), whereas this one computer is getting 1Mbps.

Please advise any further info I can give, this is driving me mad!

Yeah, Arch is funny like that...

# pacman -S wireless_tools

Yep, I was on it already:

Re: Very slow internet rtl8192ce

OK never mind, I thought it may have been the power management...

Have you tried the LTS kernel?

Re: Very slow internet rtl8192ce

OK, I've just switched to lts:

[mike@mike-pc ~]$ uname -a
Linux mike-pc 3.14.37-1-lts #1 SMP Thu Mar 26 21:16:17 CET 2015 x86_64 GNU/Linux

And I can see it is a *little* faster (3.82Mbps), but nothing compared to 27.08Mbps on my phone on the same wifi network (and physically next to PC).
