ebay usb wifi comparison , stick on the left has obvious advantage, an antenna after trying these out on windows and linux. was able to get solid signal very easily through 3 buildings and 100 feet. also had least disconnection issues.
Here we have some of the better priced routers on ebay. if you need a nice openwrt beginner router for your daily driver ide recommend archer c7 because of the dual band 5 ghz mode + the easy webflash option. pickup a c7 v2 router for under 80 dollars.
The cheepest more advanced option for a wrt router would be a a5-v11 $8 router with a usb hub and USB ethernet adapters.
A few pictures soon, maybe an adhoc writeup.
Add more USB ethernet ports if you want more.
If you want to setup a public hotspot consider using a openwrt tor router it gives you annonamys traffic for both yourself and public so the ISP wont bother you if someone misuses the service.
Quality of service pack can limit the download and upload speeds.
opkg install luci-app-qos
Another good way to minimize security risk is to block in/out udp traffic on router. also limit outgoing traffic with iptables makes running a vnc server harder to do in bursts.
iptables -A OUTPUT -m limit –limit 1/s -j ACCEPT
iptables -A OUTPUT -m limit --limit 10/s -j ACCEPT
- iptables -L –line-numbers
- –limit-burst 3
- –delete -D
# iptables -A FORWARD -p tcp –syn -m limit –limit 1/s -j ACCEPT
Furtive port scanner:
# iptables -A FORWARD -p tcp –tcp-flags SYN,ACK,FIN,RST RST -m limit –limit 1/s -j ACCEPT
Ping of death:
# iptables -A FORWARD -p icmp –icmp-type echo-request -m limit –limit 1/s -j ACCEPT
remove rule by doing
iptables -D OUTPUT -m limit –limit 1/s -j ACCEPT
