Multiple Routers in One Cement House
If you're stuck supporting 2. If DHCP is on this router then it will fill in the gateway automatically. Ask your question anytime, anywhere, with no hassle. If you don't have existing gear that you can salvage - it's cheaper and easier to just purchase one of these. A very useful answer, thank you.

Problems With Two Wireless Routers In The Same House

The Best Wireless Routers of 2018

Another annoying issue is that every time the power is cycled on the Verizon router, or Verizon pushes down an update, I need to go back in to the web interface and re-enable the coax network. The benefits are great though, the Linksys routers seem to be a lot more powerful, handling more connections and speed than the Verizon router. Also with the custom firmware, they support better throttling of certain protocols, and have a bunch of other features.

Just my two pennies. It's a free wireless utility that shows you hotspots, signal strength, and channels for networks in range. Some of your signal strength issues could be from interference from neighbor's Wi-Fi, it's really easy to identify what channel you should use. It gives you a real-time graph similar to your Wikipedia graphic showing what channel each access point is on.

It's been a lifesaver at my house where we have a dozen Wi-Fi networks in range. With WDS or a repeater the second access point is basically receiving the WiFi signal from the main router and retransmitting it on a different channel. In Scott's solution he is taking a router and tricking it into acting like an Access Point, so the backhaul to the rest of the network is wired not wireless.

That is a much better solution as you are effectively doubling your total WiFi bandwidth. You can eliminate about half the steps if you just use an Access Point instead of a router, but if you already have a router sitting around then disabling DHCP is an easy trick to save you from having to buy yet another device.

Scott I set up a Wireless Distribution System WDS about a year ago using two Linksys routers one downstairs and one upstairs and it has been working flawlessly ever since. I simply added a range extender to support wireless access in a 3 floors house. However I am thinking about doubling them with wireless routers that do NOT hand out ip addresses but add extra security protocols: Monday, September 13, 5: However, as you point out, folks have piles of standard routers lying around their houses, as I did, so it's a reasonable solution.

I updated the post, just to be clear. This is not a repeater, it's a second AP plug directly into the first's hub. Sveasoft released Alchemy v6. It runs the phone and TV at my house also, but I just asked folks, gave them a heads up and rebooted.

Still, it IS a valid alternative as you rightly point out. RHertzler - Only if you know your neighbor's wifi security password. Monday, September 13, 9: You'll get an IP no matter which AP your wireless associates with.

I did this years ago I guess as you get older you loose your hearing range. I am surprised you use DHCP for everything. I have my DHCP set to start at. This is especially nice because since I did this I never see the "another device already has this IP" since the routers I have seem to loose there DHCP lease tables on restart.

Glad to see you are embracing teh Wifee! Tuesday, September 14, Test with Google OpenID that steaming pile Tuesday, September 14, 4: Scott, Have you found any problem changing from wifi zones with an iPhone or a Windows Mobile?

I have a similar wifi configuration in my company and if I change wifi zones with this kind of devices on, they stop working and I have to turn off them to be able to reconnect.

Wednesday, September 15, 1: Wednesday, September 15, 7: A couple of thoughts: You can get an inexpensive power-line based extension point to bridge two or more wireless routers even if they don't support WDS and if you don't have a hardline between the two. Many newer wireless router vendors now simplify this process by selling range extenders and access point gear.

If you don't have existing gear that you can salvage - it's cheaper and easier to just purchase one of these. Friday, September 17, 3: Thanks Scott, this was really helpful. I've been wanting to do this for a long time. Just never got all the settings quite right. Saturday, September 18, I configured two of my linksys routers as you specified above, but when you move between the routers, it doesn't pickup the stronger signal.

I was hoping it would be able to automatically switch at some point. The only way I can get it to switch to the stronger signal is to manually disconnect wireless and then reconnect. Did you run into anything like this? Do you have any insight into how to make your laptop pickup the stronger signal?

Sunday, September 26, 4: It seems to me that you could avoid making any changes to the first router if you assign the second device an IP outside the usual DHCP range for that device -- say, Sunday, September 26, 5: But then I'd need to change the subnet mask from Wednesday, October 20, I need to set up a wireless network in a large room that will receive several guests at a upcoming symposium.

I searched the web how to solve any problem of signal coverage that may appear and several websites, suggested an approach like yours: With the problem of signal coverage solved, a coworker brought another worry: Would it work for roaming clients?

Thanks in advance for any help. Thursday, October 21, 6: Hey Scott, Thank you so much! We had been trying to figure out how to get wireless internet up to our Tiny House from the main house at the Buddhist Retreat where we live.

The plans you laid out worked perfectly along with a ft. Cat6 waterproof cable dropped into a conduit! Anyway, just wanted to say thank you! Friday, October 29, Hey Scott and others , Great article -- thanks! Everything works fine, except that my devices won't get an IP address assigned if they connect to the secondary router first. If they connect to the primary router first and I carry them to the area covered by the secondary, they keep their connection to the 'net.

Any ideas on how to make the secondary router acknowledge an IP address request and forward that? Sunday, November 21, 3: I have a second 3Com router, which would seem a free way to boost the signal.

However, I'm a little unsure of the best way to configure it. Wednesday, December 01, 8: Are you looking for wireless internet availabilty in your area? Now you can find wireless internet providers with the best price and all local and special discounts.

Check out the details of wireless internet at http: Monday, December 20, 6: That way if one of them tanks, you're still getting a local IP to attempt connecting and diagnosing. Wednesday, December 22, 8: Link them on the internal side, as below, if you like, but it's not important.. You could go with two separate SSIDs, and essentially two completely distinct installs, but there's some benefit to sharing one broadcast domain.

It'll work like a dumb hub with sprinkles, giving you the AP extension and a few ports, but in a bridged setup and not a NATted setup -- because if you're hooking 2 to AP 1, your hosts connecting to 2 will need to traverse the NAT in 2 just to get to 1's internal-side LAN clients, which is no good if you're doing any peer or serving from a host on 2. Saturday, January 15, 5: I intend to replicate this setup in my home in a few days.

I do have a follow-up question, though. In the above case, what channel would that be? Sunday, March 13, 8: Great source of information everyone One of the entries will be the router and will list a gateway IP address. Within the console will be a wireless setup menu, and that is where you can change the channel.

Doing that will probably reset the router. When it comes back, go to the control panel on your PC for the wireless card it may be controlled through Windows or through the manufacturer's own utility. Look at the list of nearby networks. If you see yours, select it, set up a profile and connect. If you do not see it, usually because you have set it NOT to broadcast its ID, then you will have to open the existing profile for it and edit the channel number to the new setting.

That's it, and good luck. In the US, a Wireless G router uses part of the 2. If you have not told your router what country you are in during setup, you may not see any choices other than channel If you see only one competing network, on channel 11 for example, the best performance for you will be to go to the other end of the band, channel 1.

If there are many different networks in your range, spread over a lot of channels, look for a channel which is not used and does not have a strong signal competing on either the channel just above or the channel just below. The other thing to watch out for is that the 2.

If you get phone interference and you can set the phone channel, try to avoid that channel or to change the phone channel. If you cannot change the phone channel, try setting your router to channel 1 or channel 11 to avoid the middle of the phone band. Shopping for a new car this weekend?
