Cant update DC112A to latest Firmware

Hi,

When I do a firmware check from within Netgear Genie it says it is the latest (V1.0.0.42_1.0.60) but when I check on the Netgear web site it says the latest is V1.0.0.62_1.0.60 which is 8 updates more. So I downloaded & extracted it & tried to upload it manually it says "This firmware file is incorrect! Please get the firmware file again and make sure it is the correct firmware for this product."

Anyone got a fix for this?

Thanks

    I know this has been asked before but I can't seem to find the answer.

    I have several 810s mobile hot spots. I bought a DC112a to extend the signal & added an external aerial & all was fine for a while then all of a sudden no internet. When I looked at the 810s mobile signal strength & the was just a circle with a bar through it. I found if I took it out of the cradle the signal returned so I connected the aerial to the 810s then to the cradle via the USB & again this worked for a while but then did the same thing. Take it off the Air Card & it worked perfectly (Mostly)

    I tried my spares & they all did the same thing. This is all post 2016 & I am sure all devices are the latest firmware. Upon checking 810 build date is Dec 2019 NTG9X40C_11.14.08.40 & I'm sure I updated the 112 too.

    I couldn't get it to work so I bought another & without going into it the above happened to the new one.

    As soon as any of my 3 or 4 810s are placed in the cradle the 810 loses signal.

    Original it was just too boost the signal but I have a few spare old routers they can be configured into wifi extenders but they need to plug into a LAN point to do this.

    Has anyone else sorted this out?

    Cheers

    After downloading the firmware zip file, do you extract the actual firmware image from the zip file?

      Yes but to be honest it was a long time ago. I stopped using it/them because of the signal fault but I want to start using the cradles again so I can set up some old router/modems I have that can be configured to be wifi extenders.

      I'm no computer expert but I've built, programmed, networked computers/laptops etc. for years. Back when dial up was new. 

      That's not to say I don't make rookie mistakes. The above reply by myself case in point. That was suppose to be another question, don't know how I managed that.

      Thanks CrimpOn

      Any other ideas?
