my laptop with this wifi card:

06:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8723BE PCIe Wireless Network Adapter

    Subsystem: Hewlett-Packard Company Device 2231

    Flags: bus master, fast devsel, latency 0, IRQ 33

    I/O ports at 2000 [size=256]

    Memory at f0400000 (64-bit, non-prefetchable) [size=16K]

    Capabilities: <access denied>

    Kernel driver in use: rtl8723be

Have many wifi problems.

After some minutes, i can't navigate or use the mail or ping something, i simply disable and enable the wifi and all work again.

Actually i have ubuntu 15.04 for some reason, but the same happen also with 14.04 or 14.10.

I would do this echo "options rtl8723be fwlps=N ips=N" | sudo tee /etc/modprobe.d/rtl8723be.conf
and reboot to see if it helps.

If can change the router settings, see if the encryption is set to WPA2 only with no TKIP enabled, change it from auto channel to a fixed channel and see if it helps.

In 14.04, I recommend that the 3.19 backports be used as it fixes most issues with the RTL8723BE
