Network driver unstable in Arch

I got an Compaq presario CQ 57 currently running Fedora 20, 64 bit.

Everything works fine in F20 or in Windows. But when i install Arch 64 bit on it, i simply loose my internet connection or it get heavily unreliable. It is so bad i installed F20 instead of Arch.

The wireless network adapter is a RALINK card ( it is called when you download the driver to Windows )

Output of lspci -v

01:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller (rev 05)
	Subsystem: Hewlett-Packard Company Device 3674
	Flags: bus master, fast devsel, latency 0, IRQ 43
	I/O ports at 3000 [size=256]
	Memory at d0404000 (64-bit, prefetchable) [size=4K]
	Memory at d0400000 (64-bit, prefetchable) [size=16K]

	Kernel driver in use: r8169

	Subsystem: Hewlett-Packard Company Device 1629
	Flags: bus master, fast devsel, latency 0, IRQ 18
	I/O ports at 2000 [size=256]
	Memory at d4400000 (64-bit, non-prefetchable) [size=16K]
	Capabilities: <access denied>
	Kernel driver in use: rtl8192ce

So anyone have an solution to fix the unreliable firmware for my wifi adapter ??

Any help appreciated

Re: Network driver unstable in Arch

Are both F20 and Arch using the same module (kernel driver)?

02:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter (rev 01)
...
    Kernel driver in use: rtl8192ce

Also, use code tags. And pick a better thread title; "Unknown hardware problem" is just not an accurate description of your issue. "RTL8188CE unstable in Arch" would be better, IMO.

Re: Network driver unstable in Arch

Alphaniner has your most likely solution, find out what module Fedora is using but if you do a search on these forums for rtl8188ce you will find a plethora of posts about problems with this wifi adapter.  Performance seems to be quite hit or miss.  On my netbook which has the same rtl8188ce and uses the rtl8192ce module, performance is generally good.  There are many solutions or suggestions posted in the forums here.  Good luck.

The wireless network adapter is a RALINK card

Just to avoid any confusion, it's actually a REALTEK card - it even says so in your lspci output.

Re: Network driver unstable in Arch

Why did you narrow the focus down to the driver?   There are other possibilities, for example:  Arch provides several mechanisms through which wireless networks may be controlled.  Netctl, wicd, and Networkmanager services exist.  In addition, it is possible to run dhcpcd and wpa_supplicant as either services, or under the control of one of the more integrated services I mentioned above.  If you have configured your system to run more than one network management tool at the same time, disasters similar to those you describe canwill occur.

Re: Network driver unstable in Arch

That was my fault, at least in part. When Realtek is involved, I always assume it's the crux of the problem.

Boy, is not that the truth    But... if he is running the same driver in both distros, I would wager on conflicts between the upper level tools.
