[Kernel-packages] [Bug 1445840] Re: 10ec:8176 rtl8192ce 200-3200+ms latency on 802.11n 2.4GHz network with no load
Upstream long ago issued a patch intending to fix the originally reported issue for my hardware only. Also, recently upstream has revamped the driver. As I don't have the hardware anymore, I cannot confirm the results. ** Changed in: linux (Ubuntu) Status: Triaged => Invalid -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1445840 Title: 10ec:8176 rtl8192ce 200-3200+ms latency on 802.11n 2.4GHz network with no load Status in linux package in Ubuntu: Invalid Bug description: Fix patch: https://www.spinics.net/lists/linux-driver-devel/msg80063.html With a Asus PCE-N10 PCI-E Adapter Wireless N I have 10-20% packet loss on a 802.11n 2.4GHz network, 2-3200ms latency pinging just the gateway 192.168.1.1, with no network load on either the router or the WiFi chipset. The computer is ~4 feet away from a Verizon Jetpack MiFi 5510L connected to a power source, with no obstructions between them. Other clients (Ubuntu with different chipset, Windows) don't have this problem. With the router on battery only, Vivid live environment and mainline 4.x, situation has improved, but still get bursts of 2 packets with 300-450ms every 50-100 packets, with ~1% packet loss.

[Kernel-packages] [Bug 1445840] Re: 10ec:8176 rtl8192ce 200-3200+ms latency on 802.11n 2.4GHz network with no load
** Description changed: With a Asus PCE-N10 PCI-E Adapter Wireless N I have 10-20% packet loss on a 802.11n 2.4GHz network, 2-3200ms latency pinging just the gateway 192.168.1.1, with no network load on either the router or the WiFi chipset. The computer is ~4 feet away from a Verizon Jetpack MiFi 5510L connected to a power source, with no obstructions between them. Other clients (Ubuntu with different chipset, Windows) don't have this problem. With the router on battery only, Vivid live environment and mainline 4.0, situation has improved, but still get bursts of 2 packets with 300-450ms every 50-100 packets, with ~1% packet loss. + + Upstream post: + http://www.spinics.net/lists/linux-wireless/msg136921.html The following did not provide a WORKAROUND: sudo nano /etc/modprobe.d/rtl8192ce.conf options rtl8192ce ips=0 fwlps=0 Attempted to use older Asus provided driver from http://www.asus.com/us/Networking/PCEN10/HelpDesk_Download/ : sudo make make[1]: Entering directory '/usr/src/linux-headers-4.0.0-04-generic' gcc: error: /lib/modules/4.0.0-04-generic/build/include/linux/autoconf.h: No such file or directory gcc: fatal error: no input files compilation terminated. scripts/Makefile.build:49: *** CFLAGS was changed in /home/moniker/Desktop/Linux/HAL/rtl8192/Makefile.
