Hello All, Wireguard setup from local server to a Google Cloud Instance server,both Debian Bullesye The local server acts as an ltsp server for thin clients running dnsmasq. After learning all the MTU settings curves on a WireGuard setup, everything works correctly,,,almost. On the bridge interface that has the internal nic and the wlan attached the ethernet to clients works fine. the wifi clients gets internet but very very slow When do a Google speed test the wifi client jumps up,to expected download speed ,just for a second then falls back down to almost 50kbps. Have tried manually setting the bridge to many different mtu's trying to see if this helped it did now Almost certain this has something to do with mtu on the wifi interface.Wireshark shows now,, no fragmented packets on any interface. This is an Intel wifi adapter.. hostapd.conf interface=wlp3s0 bridge=bridge0 driver=nl80211 country_code=US ssid=myssid hw_mode=g channel=6 /etc/network/interfaces auto bridge0 auto wlp3s0 auto enp2s0 iface wlp3s0 inet manual iface enp2s0 inet manual #iface wlp3s0 inet6 manual #iface enp2s0 inet6 manual #bridge setup iface bridge0 inet static bridge_ports enp2s0 wlp3s0 address 192.168.67.1 broadcast 192.168.67.255 netmask 255.255.255.0 post-up iptables-restore < /etc/iptables.up.rules post-up ip6tables-restore < /etc/ip6tables.up.rules # post-up ifconfig wlp3s0 mtu 1460 && ifconfig enp2s0 mtu 1460 # gateway 192.168.67.1 #bridge_stp on Thank You _______________________________________________ Hostap mailing list Hostap@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/hostap
