From Zero to Xfinity
Comcast subscribers who use the rented modem get to take part in the festival of wifi —
xfinitywifi. Comcast also blocks Samba which makes things hard because I would like to mount my remote development filesystem on my main Windows workstation.
If you are only interested in accessing Samba over Comcast internet, jump to Multi-WAN + Xfinity + Samba - Part 2/2.
I wanted faster internet at my second work location to supplement cellular tethering. As an existing Comcast subscriber, I am able to get internet using other Comcast subscribers’ broadcast
xfinitywifi hotspot networks.
Some adjacent tenants use Comcast and they participate in
I read Mike Solomon’s post on how he doubled his bandwidth with an OpenWRT multi-WAN setup and wanted to see if I could get a stable setup using two
I followed roughly the same steps as Mike and did some additional configuration to complete my multi-WAN setup and get Samba working with a Comcast internet connection.
If you haven’t read Mike’s post yet, follow up through his step 5 and come back for more multi-WAN action. After setting up our network for dual WAN with Mike’s instructions, we have the below setup:
1. Connect to
Go to Network > Wifi.
Scan and connect to a second
xfinitywifi network with your router’s second wireless radio.
The second wireless radio may be named

Use the sort buttons to the right to move your desired policy to the top of the list.
5. Edit network config for wan3.
Add the following to
config route 'default_wan3' option interface 'wan3' option target '0.0.0.0' option netmask '0.0.0.0' option gateway '192.168.1.1' option metric '30'
We now have the below setup:
Does it wifi?
Each surrounding xfinitywifi network provides about 16mbps/2mbps. I tested my setup and can get 32mbps/4mbps, confirming that load balancing across two wireless networks is working as expected.

- Samba connectivity in a restricted environment such as Comcast
- Setting up OpenVPN client on OpenWRT
- Setting up a split tunnel to maximize multi-WAN speed up
