wi-fi and range extender - no internet

I switched from TW plan to Spectrum plan and Spectrum switched my hardware (modem and router both).  Now even my 2gh wi-fi will not reach my patio.  I now have a new Technicolor modem ( DPC3216) and a new Spectrum router which broadcasts in 2.4 and 5ghz wi-fi.  Problem is, the wi-fi signals from this new router do not broadcast as far as my old TW equipment, and I can't connect with my android (2.4) and iPhone7 (5ghz) telephones from my patio at the far end of the house.  My wife bought us a Netgear Range Extender AC1200 EX6120 and I cannot get it to work.  Both phones connect to the new networks (2.4 & 5ghz) quickly, but neither phone will connect to internet.   We can connect to the old network names OK and do get internet (but not out on patio).  I called Netgear support and over 2-3 hours we tried many things including factory reset on the extender, but Netgear (and I) finally gave up trying to get internet (we couldn't even find a way to download/install current firmware) .  We agreed that I should return the extender.   

1.  is this a common problem?

2. Should I try some other extender?

3. Does Spectrum offer an extender that would work?

4. This is an average size 1 story home install, and of course cost is a consideration.  Please let me know if I should do something different - and if so, what SPECIFIC router and/or extender  should I buy to work with my Spectrum modem?

Re: wi-fi and range extender - no internet

Do you have an all-in-one?  (Modem + WiFi Router)

Are you paying Spectrum for Home Wi-Fi?  (Would be a $5 per month adder on your bill.)

Is your router using a "crowded" channel?  (When you scan for wireless networks, especially ones on the 2.4 GHz band, how many of them are on Channels 1, 6, and 11?)

Re: wi-fi and range extender - no internet

New Technicolor cable modem from Spectrum.  New router from Spectrum.   Units are separate.  They were installed to replace old TW/Spectrum hardware because Spectrum REQUIRED that happen as part of changing from a TW "plan" to a Spectrum "plan".   I have phone, TV, and internet with Spectrum and I do pay for wi-fi.   I changed plans to lower monthly cost - I changed from TW's ultra (350Mbps) internet to Spectrum basic (230Mbps)  internet- speeds I quoted are via Ethernet to my desktop PC.   Wi-fi on 2.4ghz I get 30+Mbps.  On 5ghz my wife gets 120-170Mbps (iPhone7).   

Both 2.4 and 5ghz are being broadcast from new router and both signals are just fine from Spectrum equipment.  Have never had any problem with interference  - ever.  Problem is that the new router just doesn't broadcast the signals quite as powerfully as my old Spectrum cable/modem/router that was a single box.  Wi-fi signals no longer quite reach my patio as they did from my old Spectrum Technicolor cable/modem/router - so I wanted to use the extender to get the signals to reach further - at least to my patio.   I live in a single story house and there are not many wi-fi broadcasts from other homes that I can see. 

Spectrum router is broadcasting 2.4ghz on channel 1.

Spectrum router on 5ghz - control channel = AUTO,  current ctl. = 36

Re: wi-fi and range extender - no internet

Is the extender itself actually connected to the network?

Did you use the same passwords as the router for the new extender networks?

All LEDs on the extender are green?

Did you connect the extender via the WPS method or the browser method?

Can an ethernet connected device connect to the internet via the extender?

Re: wi-fi and range extender - no internet

The extender connects quickly to the router and my phone expansion of the connection  window shows that the connection is very good (but no internet).  Wife's phone connects to extender just fine on 5ghz.

Neither phone device/connection (my 2.4 Android phone and wife's iPhone7 on 5ghz)  is able to access internet using extender wi-fi signals.

Password is the same for both the old and new networks.  New network names are same as old but with "_ext" something-or-other added to the end of network name.  No problem with that - it matches what install guide shows will happen.

All LED's on extender are green.

Connected  with WPS - both 2.4 and 5ghz.

Connected the extender directly to PC via Ethernet to try to install downloaded firmware upgrade file.  Logged into extender from PC via that Ethernet cable but we (Netgear support and I) were never able to see anything to click on to get the firmware upgrade to install.  Did not see anything on Netgear's Network Genie to click on for firmware upgrade.  Not sure whether current firmware level is same as what came on extender which we just received new from Amazon.  Also connected via wi-fi with phone 2.4 to extender's app and couldn't see anything to click on to load firmware.

I don't think we tried connecting router to extender with Ethernet cable (if that is what you meant).  Also did not try to connect any device to extender (other than my PC) using Ethernet cable.  I don't think I have any Ethernet devices that I could do that with other than my laptop, and we did not try that.

Returned extender to Amazon for refund.

Re: wi-fi and range extender - no internet

Save yourself some money, and stop paying for "Home Wi-Fi" from Spectrum.  Buy your own wireless router - one with external antennas - and get control of your home LAN.  Your ruter will pay for itself.  And if the previous router you were using is owned by you - by all means use it.

 

For the 2.4GHz network, perform a site survey.  If everyone around you is on 1, 6, and 11, go for an unused channel half-way between the others..  i.e. - If 1, 6 and 11 are heavily used, I'd set my router to use 3, 4, 8, or 9.  You want to be the only WLAN on a channel.

 

Can't help you with the 5 GHz.  I have a router that uses it, but I don't.

 

In terms of Wi-Fi Extenders, I'd rather use an old router set up as an access point, connected via ethernet to the router, and put that router on yet a different channel.

Re: wi-fi and range extender - no internet

I do not own a router.

On my Spectrum bill I do see $5.00 for wi-fi service - is that for the router?   I do not see a separate charge for the Spectrum router device itself. 

I always rented from TW or Spectrum.

My worry was that when I had problems, that Spectrum would blame my owned router and me (not being a tech) would be powerless to argue with Spectrum's support.  At least with (only) Spectrum hardware and software I could always say to Spectrum "it's your stuff - fix it!".  

So, since I have no owned router, should I buy a router? 

And then the question is - what router should I buy?  I'm not a tech and I do not know which router would be best for my situation.  I know I need AC and dual band 2.4 & 5ghz.  I know it needs to be compatible with the Spectrum/Technicolor DPC3216 modem that I rent from Spectrum.   I know it needs to send more powerful wi-fi signals than the new Spectrum router I am renting now  (it is labeled as Spectrum, but no model number).   If it isn't stronger than the Spectrum router I have now  I will still have no good wi-fi signals on my patio.   What router should I buy?

And if I do buy my own router, do I need to contact Spectrum at all to get it going, or do I connect it with Ethernet cable to the Spectrum cablemodem, then Ethernet cable to my PC, and then simply log into it from my PC (Ethernet) and specify my proper network names and password for the 2 wi-fi bands?  And then maybe reboot the router to check out connectivity via Ethernet and wi-fi's.

Re: wi-fi and range extender - no internet

have to agree with @dstoffa here.

 

Sortof an Occam's Razor kinda thing... tring to integrate the wifi extender may be complicating things more than necessary, considering that is the only thing you truly have control over and not very savvy with the technology.

 

Grab one of the mid to upper tier Netgear routers.  Even their AC-1750/1900 models are prety robust, and the set up is pretty simple and for the most part automated.  My daughter's linksys went AWOL at her college apartment (3 hours away), and her trying to get help from them was an exercise in futility, as she pretty much just knows how to reboot it and how to put in the password for their PS4's, phones, etc.  Ordered her a $99 Netgear AC-1750 for her to pickup at the local walmart, and she got the apartment up and running in about 30 minutes from opening the box.

Re: wi-fi and range extender - no internet

This may be a simplistic approach, but is your wi-fi router centrally located?  It would seem to me that any commercially available wi-fi router should be able to cover a standard home. Now if your router is at one far end of the house and you are trying to reach the other end of your property outside you might be stretching it a bit. The router should be located in the center of the coverage area.   Also is your wi-fi router up off the ground?  There is a reason TV Stations put their antennas on the tallest structures available.  I would start here before going to any more complex and expensive solutions.

Re: wi-fi and range extender - no internet

@LGT  router is on a shelf, about 5' above the floor, about 3' from the desktop PC that it is connected to via Ethernet cable.  My desktop PC needs to stay in the front room office it is in now, which means that the router needs to stay near it so that a long room-room Ethernet cable is not required.  I can't be punching holes in walls and ceiling, trying to run new cables from room to room or thru the (impossible-to-access due to the truss jungle) attic.

The router has been located where it is now for many years with no wi-fi problem until Spectrum replaced the old Technicolor cablemodemrouter with the new Spectrum modem and separate router.     So the router is not centrally located now,  never has been,  and cannot be moved.  I need for wi-fi connected cell phones to work well on my back patio.  And yes, the signals need to pass thru 3-4 walls to reach the patio.

Apparently, I need a router that will throw the wi-fi signals a greater distance than the Spectrum router.  I have asked in this string for someone to tell me about a strong-signaling routers but  only RAIST5150 has replied.  He/she mentioned the Netgear AC1750 as being "robust" but I don't know, of course, whether that router would throw wi-fi signals as well as or better than my old TW Technicolor cablemodemrouter.  Hopefully someone who reads my post can recommend a specific router as being "one of the most powerful" (signal-wise).       

I have returned the Netgear range extender to Amazon because I and Netgear support were not able to get it to connect to internet - although it connected just great without internet to the 2 cell phones I tried - just no internet.  Spectrum does not offer a range extender.  I hate to go to a mesh system  because of cost - Google offers a 1 pack and a 3-pack but no 2-pack, and a 3-pack would be overkill at high cost.  Buying 2 singles would also cost too much.
