I have this problem with my laptop running Debian Jessie.
I cannot gain any kind of network visibility on it from devices in the same network. I can't ARP the laptop, but the strangest thing is that if I ping from the laptop going out to somewhere else on the network, -then- I can communicate properly with the laptop from the same host that the laptop pinged, for a short period of time.
My laptop can ping anywhere out onto the network, but can't be pinged unless it pings first.
All devices are on the same subnet, share the same default gateway.
Using Wireshark shows me that it literally is not receiving any ARP requests from anywhere on the network. My computer isn't detecting the request.
My iptables have no restrictions, so it can't be a firewall problem.
My router also has the lowest security values.
I'm convinced that it's somehow related to
because that post exhibits exactly the same symptoms as my own setup, although that one specifically references Ubuntu's broadcom drivers, while I'm using Debian's Atheros drivers.
The output of lspci -knn shows network/driver setup:
04:00.0 Network controller : Qualcomm Atheros AR928X Wireless Network Adapter (PCI-Express) [168c:002a] (rev 01) Subsystem: Quanta Microsystems, Inc EM303 802.11bgn Wireless Mini PCIe Card [AR9281] [1a32:0303] Kernel driver in use: ath9k
Is this an issue with Debian? Is there any process I can do to fix it? I'm not too familiar/knowledgeable as far as handling drivers in Linux.
After uninstalling the
network-manager package, the system ceases to have this problem. I've read reports of strange things happening when both the
network-manager and the
wicd packages co exist on the same system. I'm still observing the system now, but as of the current moment, everything seems to be functional.
