More Crappy Router Questions. Need Some Help

I thought a new thread would be best... Didn't want to deny someone of some well earned EZ-Bucks...

Have a problem... Similar to Dave's problem and I was going to add to his thread instead of making a new one... Anyway... Both my EZB4 will connect to the network no problem, however ARC can only find one of them at a time... meaning I cannot have more than one ezb4s connected to ARC at any given time. The scan tool will only find one ezb... usually the first one powered on... Long story short and judging by what Dave went through I am guessing its a router issue... I have an all in one router/moden ... an SMCD3GN from SMC.... I rent it from my local cable company by the way... So my question is should I turf it and just use a modem from them and then buy my own router?... Also need to mention that I barely get 30ft from the router when I start to get disconnect problems so range sucks...

Thanks Richard


Upgrade to ARC Pro

ARC Pro is more than a tool; it's a creative playground for robot enthusiasts, where you can turn your wildest ideas into reality.


Rats Richard R. I replied to your other thread.


If that doesn't work than your router needs to be upgraded to something from this era:)


You're a funny guy DJ.... My all in one is a few months old... Well, it could have been sitting in Roger's warehouse for the last decade or so... who knows... LOL

This time both got picked up in the scan, but most of the time only one does... I think I am going to take Docs advice and update my router anyway for no other reason but maybe to get me more range and more solid connections...

I have to give this one to Doc, but thanks for the video nevertheless DJ...:)

Thanks Doc!



Keep in mind that making new threads on existing discussions that cover the exact same issue is going to add confusion to new comers. When ppl search for help and they get thirty threads on the same topic - all pointing to one topic... It helps no one.

And it's an abuse of the credit system:)


Sorry DJ... Understand what you're saying so completely understood... I really didn't mean any harm here...


So Doc, I am looking at the ASUS RT-N56U on BestBuy's webside... You really recommend this? Has good range?

Thanks Doc


I would never expect harm from anyone in our community - specially you:)

I had the Asus RT-56. It was a great router! We don't use it anymore now that there are so many devices on our network. We now use the new Linksys WRT1900AC at the EZ-Robot Office. It is expensive but great for a large network. At home I use a $30 D-Link:)


Whew!, that's a relief... Thought you might ban me from EZ Robot... Without my daily EZ Robot fix, I might have to pull a Rob Ford and head for the local crack dealer and liquor store...:P

Thanks, more router research needed....

Cheers Richard



Robert R. So Doc, I am looking at the ASUS RT-N56U on BestBuy's webside... You really recommend this? Has good range?

I have two of them running here at my shop. One on each internet provider. Good range and they work well.

I'd always highly recommend any router that's capable of running (or comes with) DD-WRT firmware since this is possibly the most user customisable router firmware I've ever come across.

There are a lot of routers which the firmware supports, check out the database.

But any decent router will do. The main thing to check really though is if it supports static IPs based on MAC address, this will help a lot if you have a lot of robots running around the place which may be turned on and off a lot. It will pretty much eliminate the requirement for searching for the IP each time it changes since it'll never change.

I personally use a Buffalo WZR-HP-AG300H at home which is awesome (great strength & range, no problems picking it up when I'm all the way outside in the car tinkering around with things I shouldn't be) but it was expensive.

At work I use a Linksys WAG54GS router but work wifi is only really used for phones since all PCs are hardwired, still it gives no problems and great range (I know when my boss is almost back in the office as his phone connects to the WiFi which gives me chance to close the EZ-Robot website before he notices...)


Appreciate your help too Rich... I am at least now going to be able to make an intelligent decision on which router to buy...

Cheers Richard


I personally like a separate access point on my network and let the cable modem just be a cable modem. I have used Engenius access points with a lot of success. Something like this would go great and could be mounted like a fire detector in the middle area of your house giving you great wifi throughout. It is PoE so you can run one cable and be done. You just need to pickup a power injector to go with it if it doesn't come with one.

Engenius AP


I've got my new network set up as @d.cochran suggests with the Engenius access point he points to and a ASUS RT-AC66U Dual-Band Wireless-AC1750 Gigabit Router. Works real sweet and I have plenty of signal near the robot. This set up and static IP addresses for the EZB's in the router took care of all my connection problems.


Thanks guys... I have decided to go the route of disabling the wifi in my current all in one (just use the modem part) and going with a new router.... Deciding between a D-Link Dual Band Wireless AC750 Router and the one Robot Doc recommended ( ASUS RT-N56U )...

Thanks again Richard


... Ok, can't sleep so I have been thinking.... Is there any reason why I need to disable the wifi on my current all in one (router/modem setup) when I add the new router? Can't I just plug in the new router and run 2 wifi networks? And will that cause either or both of the networks to run slower due to any limitations with the modem?

Thanks Richard


You can run two WiFi networks. It would be a good idea to have each on it's own channel. Also use low used channels. Do a scan to see what other people living around you are using. YouTube videos will show you how.


If you run rwo, they need to be on different subnets or you will have conflicts with having two dhcp servers on the same network. Data may or may not be able to cross the networks (your new one will be able to get internet from the old, but devices on one may not see devices on the other. My fios router does allow cross device traffic, but technically 192.x.x.x traffic should not be routable between routers, so I consider myself lucky).


Thanks Alan.... No biggie, I will disable my current wifi and run exclusively off of the new one... At least until I learn more about network settings and such...


I normally leave them on the same network and allow them to hand off to each other. I actually have one of these on one side of my house and another on the other side. Somewhere in the middle, the device is handed off to the other access point. It is seamless and very quick. I can walk the the property line of my city lot and have 100% coverage from curb to the back fence and from side fence to side fence. That may be over kill for you but I plan on using it to build a mower one day and allow it to be on Wifi.


@d.cochran... That's the coverage I want too... I am also planning to build a robot mower at some point... Need a few more ezbs first...:)


If you have a large yard, Engenius also sells some outdoor AP's but unless you have 3 acres or so, this would be overkill. Check em out. We have gone to these in my office also. It is a sizable office (4 floors and about 2000 offices. They work well.


@RichardR, I have a suggestion to you. I remember reading somewhere that some wifi items would interfere with the ezb wifi. So, I disconnected all wifi units but the ezbs. Next, I connected and found both of the ezbs. They then worked as expected. I really did not need the other wifi units, so I just left them off.
