after using wireless for a bit I get the following when I try pinging anything:
ping: sendmsg: No buffer space available

as sooon as I switch my default gw to my ethernet interface(different subnet OFC) things are working fine
# lscpi -k
04:00.0 Network controller: Realtek Semiconductor Co., Ltd. RTL8723BE PCIe Wireless Network Adapter
Subsystem: Lenovo Device b728
Kernel driver in use: rtl8723be
Kernel modules: rtl8723be
05:00.0 Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 10)
Subsystem: Lenovo Device 5024
Kernel driver in use: r8169

I can reboot so things get back to normal, the problem is always reporducible(I don't remember it ever working)

I expect you've seen this link but according to it, you may
have a hardware issue

according to this link: https://wiki.archlinux.org/index.php/Wireless_network_configuration#rtl8723be
disabling the module parameter => fwlps: using linked fw control power save
has fixed the problem
I have created the following file to modify this parameter when loaded:
/etc/modprobe.d/rtl8723be.conf:
options rtl8723be fwlps=0
======================================================================================

problem solved, thanks
