Using 2 Wifi Dongles: 1 For Internet, And 1 For Ez-Bs

Hey guys.

I discovered a pesky setting in windows that sets priorities on wifi connections.

Currently I have my ez-b on my wifi 2 connection, and my home wifi on my wifi 1 connection. Windows, as it appears, sets a random priority on each of these.

It appears to have set the ez-b connection as primary connection, but now, I cant use the internet on my home connection dongle! It has also happened vise versa.

I would connect my ez-b to my home network but we have in excess of 20 devices using that connection. With it already slow, I don't want another device slowing it more.

What my question is: How can you specify what wifi connection you want to use in say, the connection control in ARC ? Something like Wifi 2:\ ?

If I can figure this out, I wont have to constantly disconnect from the ez-b on my second connection to use the internet on my first one.

Thanks for any help I get! Tech

Change Network Interface Card (NIC) Priority in Windows

Question How do I change a network card's priority in Windows? Answer You need to ensure the network cards are in the correct order of preference in which the connections are accessed by network services. To change the priority (or binding order) of network cards in Windows when multiple NICs are on a machine, follow the below steps:

  1. Select the Start button and click Control Panel.
  2. Click Network and Sharing Center.
  3. Click Change adapter settings to open the Network Connections window.
  4. Press the Alt button on your keyboard; a hidden menu will appear beneath the location bar.
  5. Select Advanced | Advanced Settings. This window displays the order of preference in which network connections are accessed by network services.
  6. Select your Local Area Connection within the Connections section of the Adapters and Bindings tab. You will see current connections listed in the order in which they are accessed by network services in the Bindings for Local Area Connection section.
  7. Use the up and down arrows to the right to change the priority of the network cards. The network card that connects to the trading environment must be listed first.
  8. Click OK.

After the above changes of bindings for local area connection, the trader’s network card remains as first priority in the connection list.

p.s. one nic is attached by cat5 (1gb) to internet, other is 5g wireless connection to router or ezbs.

@Techno, I have over 20 wireless devices on my network and don't suffer any problems.

I have 4 Internal IP cameras, 2 External IP cameras, 1 IP room thermostat, 2 laptops, 3 phones (often more), 2 tablets (often more), 1 printer, 2 Nettop PCs, 3 Raspberry Pis, 1 CCTV DVR and 3 EZ-B V4s

That's 24 devices. Plus wired devices (8 of those).

I realise I have too much stuff for just one person...

Traffic on my network is always very high as everything comes from one of two NAS drives plus constant reading and writing to the MySQL server which happens every 10-15 seconds.

I suffer zero issues. Streaming HD (1080p) Movies from NAS drives to XBMC/Kodi is no challenge. Not even at the moment where I'm running on a backup router (since my DD-WRT one died last week) which doesn't have that good of a spec.

You will have less headaches with one WLAN and one WiFi NIC.

Connection to the EZ-B shouldn't slow down any other connections if you have decent hardware.

In fact, I've worked with offices that have 50+ wireless devices not including smart phones (so make that 100+ as I am sure by now everyone has connected to the WiFi) and have never had a complaint from any of them.


Rich, I have a cheap consumer router, and look to upgrade to a business router.

J, Thanks for the info! Got it working great! If you don't repost this as a tutorial, I will!


I agree with Rich here. I have 20 devices in one room of my house, and many more throughout the house. I do hardwire where possible and that does help a lot I am sure. My NAS is hard wired and bridged. My laptops are hard wired unless I take them to another room. My servers are all hard wired. I have wires by the beds so that the family can hard wire their laptops when lying in bed. The xbox's, TV's, BlueRay's, surround sound equipment, PS3's and PS4's are hard wired.

This leaves cell phones, tablets, robots, door locks, cameras, thermostat, glass breaks, window modules, garage door, power outlets, ceiling fans, and various other outlets in the house on the wifi. The Cell phones, tablets and robots are the most bandwidth on all of these, but this is nothing for the wifi AP's that are in the house. You can oversaturate the AP, but its pretty hard to do, however you will see a huge improvement when wired as it has far lower latency and far higher bandwidth. Wiring your more heavily used devices will go a long way if they are not yet.


@Rich and @d.cochran,

This is an issue,

not all Ez-robot users have the best routers, bridges, or network connections.

Or the ability to use and configure such.

Or the time and money to make changes to what they have.

To get their new robots (v4) working.

Just my two cents.



A lot of the time, people drop in a switch with WIFI and ignore the wired ports on the back of the router. These ports should be the first option and not the second. Switches to extend this can be found for a little as $19.

I have seen many people with their laptop sitting right beside their router, and I ask them how often they move their laptop somewhere else. They normally say never. A 6 foot cat 5 cable makes their lives so much better.

I realize that not everyone is going to run cables through their walls or is going to have an extensive network in their house. The statement was that there were too many devices on the network. The issue is that a lot of devices isn't an issue on a network. It is the configuration of the network.

The cat 5 cable costs a couple of bucks and even cheaper if you make it yourself. It might not be possible, but it is definitely the preferable solution.

@Techno, I'm currently running on my backup router which was issued free by my ISP. It's not the best router in the world by any stretch of the imagination. It's probably the worst gigabit router I've ever come across.

Even with this, I have no networking issues streaming 1080p HD content from my NAS (wired) to my laptop (which is old and only a 802.11 B/G connection) or to my HTPC (wired), even if I stream to 4 different instances of XBMC/Kodi and have my DVR constantly uploading detection video clips to my remote FTP server and having my IP cameras constantly uploading images every minute, and streaming to 2 instances of VLC on two tablets (one each).

My network is under a pretty heavy load. Yes some is wired (more than I thought as I forgot Xboxs, TVs, etc.) but there's also a lot of wireless going on too.

I agree with Mr Cochran though, wired is the way (which is why I've had CAT5E part installed for 4 years now... really should get that finished). However, it isn't a requirement.


I live in a large house and the cable put in the walls when my parents built the house are the wrong cables for Ethernet plugs.


I bought a cheap dLink router ($45 CAD) from Best Buy about 3 monts ago...(actually on DJ's recommendation)... it is SO much better than the crappy all-in-one I got from rogers... At any given time I have 10 or more devices connected and so far all my connections have been pretty rock solid (that includes all my ezb4s)... My wifi range has also increased dramatically....
