That isn't even close to the latest firmware, update it and see if it resolves, the Altalink (C8055) and Connectkey (7835) products at current levels are identical with exception to visual elements, the code base is the same, so assuming they are set the same way, if one works they both will.
If the firmware doesn't fix it the next step would be to check the time on the AltaLink (If it is off by 3 or more minutes it will fail to scan)
