Wireless dies?

Well, then, dump the entire output of

lspci

and

lsusb

and post them here.

Has to. Are you typing the command correctly? The | isn't a lower case L, it's the pipe symbol. If you just copy and paste what GG showed into the console, you should get a result.

Nope, no result -

jeremy@jeremy-GA-990FXA-UD3:~$ lspci | grep Network
jeremy@jeremy-GA-990FXA-UD3:~$

I copied and pasted.

Sadly that one doesn't give an output either.

You could use

lspci | grep Network

[/B]Set options for the mac80211 module in /etc/modprobe.d/modprobe.conf:

There's no modprobe.conf. The contents of modprobe.d are -

alsa-base.conf blacklist.conf blacklist-framebuffer.conf blacklist-oss.conf blacklist-watchdog.conf
blacklist-ath_pci.conf blacklist-firewire.conf blacklist-modem.conf blacklist-rare-network.conf dkms.conf

BTW I like your sig.

lspci | grep Network

Your wifi drivers have no user settable parameters (parm), so they either work or they don't. The auxiliary drivers (mac80211 and cfg80211) they call (which are called by all wifi drivers) have parms that can be set.

~$ modinfo -p mac80211
parm: ieee80211_default_rc_algoefault rate control algorithm for mac80211 to use (charp)
parm: max_nullfunc_tries:Maximum nullfunc tx tries before disconnecting (reason 4). (int)
parm: max_probe_tries:Maximum probe tries before disconnecting (reason 4). (int)
parm: probe_wait_ms:Maximum time(ms) to wait for probe response before disconnecting (reason 4). (int)


~$ modinfo -p cfg80211
parm: ieee80211_regdom:IEEE 802.11 regulatory domain code (charp)
parm: cfg80211_disable_40mhz_24ghzisable 40MHz support in the 2.4GHz band (bool)

The three most likely to help are max_nullfunc_tries, max_probe_tries and probe_wait_ms.

Set options for the mac80211 module in /etc/modprobe.d/modprobe.conf:

[FONT=courier new]options mac80211  max_nullfunc_tries=60 max_probe_tries=60 probe_wait_ms=3600000[/FONT]

Having the wait at 3600000 milliseconds (one hour) may be overkill. Play around with the settings and see if that helps.

lspci | grep 802

Is that the right syntax? It returns nothing at all. I get a new command prompt.

and what is your driver?

lsmod | grep 802

The results are -

mac80211 506816 3 rt2800lib,rt2x00usb,rt2x00lib
cfg80211 205544 2 rt2x00lib,mac80211

What's your wireless chip?

lspci | grep 802

and what is your driver?

lsmod | grep 802

This is on my desktop -

AMD 8-core FX-8120 3.1g 16M R

Gigabyte GA-990FXA-UD3 AM3+ R motherboard

16 gigs GSKILL F3-14900CL9D-8GBSR

Radeon HD6870

Internet is still up, and I can access it through the wireless router with my laptop.

In the Network managment settings dialogue, it shows the connection and says it's connected, when the connection has been broken. After disconnecting and reconnecting through Network Management, wireless works again.

The problem doesn't appear through regular internet surfing. It only appears when using Muon or Apt through the terminal.
