Hi,
I am equally VERY FRUSTRATED with Netgear C6300. There is another cheaper version of cable wifi router N600, but salesman from Frys convinced me to purchase C6300 (AC1750), because I have multiple devices, and iphone (5G capabilities), and 2-story house (distance), etc...All that sound good, the product looks very good too.
Bought 1st one on 7/4/2015, and activated with Comcast (Xfinity) on 7/11. The unit at first power up, without Comcast activation yet, the 5GB light comes on. But after activation with Comcast, Comcast said wait 15 mins, it will load latest updates. After several minutes, updates completed. Unit is working at 2.4G only, the 5G light did not come up. Then I called Netgear, after hrs on the phone, they had me do whole bunch of stuffs, including "ERASE", which is the reload factory settings.
After doing this, the 5G LED comes on, 5G was working. Few days later, I re-arrange my router area, which included powered off the c6300. After power it backup, then WHAT ??? the 5G light is OFF again. So, I repeated the "ERASE" operation, but no luck this time, I did other stuffs such as in the Internet section, there is "Reset to factory" (or somethign like that), I also hard-reset, using a paper clip, pushed down for 10 secs, I also did unchecked 5G, then checked it, and apply changes. A million things, anything to do with resetting back to original setting, the 5G was never able to light up again, at all. After calling talking several with Netgear, I returned unit back to Frys. And got the same c6300 model, but brand-new. Thinking something happened to the 1st unit.
Then 2nd unit got home, I powered it up, with Comcast cable connected. I know I had to re-activate the new S/N of this device. Thus I called Comcast, had me on music for 30 mins. All this time the 5G light was ON green. So I thinking, ok, may be 1st unit was really defective. After I enterred my Comcast acct & phone number, it re-actiavted my account with the new S/N. And once again, it prompted for waitin 15 for applying updates...Guess what ??? after the update from Comcast, the 5G light went OFF again !!!! I repeated verything I could, the 5G light could never lid up. Called Comcast, the lady told my Comcast only sent the command to set the speed of my internet to 25Mb for my purchase rate, and nothing else. I really doubted that. Comcast must have sent something, such as the version of Internet Hardware, or newer firmware to the modem, causing my 5G light to not function anymore. Unfortunately, I did not "backup the setting / config" prior to calling Comcast, so I don't have the original config to reload back to the modem. And the erase seemed it didn't quite reload as I though it wwould.
Now I am stuck, already 2nd brand new C6300, and no 5G light. I was so upset, that I could sleep last night, thinking of strategy how to deal with it. Neither Netgear nor Comcast can provide any good explaination, and cannot fix the problem.
I am hoping if there is ANYONE out there has similar issue, and got it resolved, please let me know. Other wise, I planned to return C6300, and may be buy N600 a lower model (cheaper), and of may be a different brand totally. Reason I want Netgear, becasue I wanted to use the READYSHARE USB drive feature....
Thanks
