The issue:
I can ping all devices on the network except the gateway (192.168.0.1) and in turn can not access outside of the network without proxying through another device.
The system:
Lenovo x230 Tablet with a Realtek wifi adapter running on Quantal:
Network controller: Realtek Semiconductor Co., Ltd. RTL8188CE 802.11b/g/n WiFi Adapter (rev 01)
The wtf:
I can obtain an IP from the router
wlan0 Link encap:Ethernet HWaddr e0:06:e6:c2:d2:e0

I can ping other devices:

I can not ping the gateway:

Things I've attempted:
Turning off fwlps, ips. Attempted to compile a driver from upstream(realtek.com) and even tried the latest daily mainline kernel for Quantal. Also tried latest compat-wireless and switching out firmware. Tested Windows 7 and verified the card worked. Tested slackware 14, Fedora, Arch and they all exhibit the same issue.
Has anyone seen this before? What really baffles me is that I can not ping the gateway. To verify I can ping the gateway from another system:
λ ~ → ping 192.168.0.1
PING 192.168.0.1 (192.168.0.1) 56(84) bytes of data.
64 bytes from 192.168.0.1: icmp_req=1 ttl=64 time=1.35 ms
64 bytes from 192.168.0.1: icmp_req=2 ttl=64 time=1.22 ms
64 bytes from 192.168.0.1: icmp_req=3 ttl=64 time=5.11 ms
This also doesn't happen outside of my network as I was able to use this laptop at UDS-R which kind of points to a router issue but anything without a Realtek adapter works :
I dont know if any Realtek developers monitor this site but has anyone run into an issue like this?
Thanks
