N450/CG3000Dv2 WiFi drop and Interface Lockup
Last week Time Warner Cable pushed firmware V3.01.06 to my N450 modem/router. Since the update, i can't go more than 24 hours without having to pull the power because WiFi drops ALL devices. After ...
I did a factory reset and have not been loosing connection for a few days. In the genie menu there is a place to backup your settings. After the reset you can restore the settings from the file you saved. The only thing it didn't restore was the user and password to access the router. The default is admin for user and password for password. Then you can sign in and change that. Still can't usb port to work.
It's been two days since I reset to factory defaults and reconfigured. So far my network connection to the CATV system has been stable as far as I can tell. (No outliers in pings to the Internet, speed seems normal, no connectivity issues I can trace to the modem.) My access to the GUI has worked consistently. I have never used the WIFI, so I turned it off as part of the reset/reconfigure process.
As far as pinging from the Genie diagnostics page goes, it is definitely buggy. If I ping a local PC, it reports no replies even though I can see the pings and replies on the PC in tcpdump. If I ping out to the Internet Genie reports timeouts but nothing shows up on the outside system. I can ping the outside system from the PC with no problems.
I am connected to TWC or whatever they call themselves these days.
I too am having this problem. I spent about 2 hours one day dealing with TWC and trying various things. When I talked to the Level 2 tech from TWC I was informed that the firmware updates get pushed from the backbone down to the device. So if the engineers decide that the V3.01.06 firmware is what the backbone is going to run off of then there is no way around it. You can do a factory reset if you want but it will pull down V3.01.06 again. I pointed out to him that the V3.01.06 firmware is shown as the Comcast configuration for the N450 (http://kb.netgear.com/app/answers/detail/a_id/25477/~/current-firmware-version-for-netgear-cable-modem-routers) but it didn't make a difference. Unfortunately, the N450 doesn't have an option to do standalone firmware update. The tech I spoke with gave me the option to do a full replace or get a wireless router and attach it to my modem. Guess I will have to get another brand of modem...
Mine is still working since I did the factory reset and is using the v3.01.06 firmware. I'm impressed that you at least spoke with a tech at TWC that understood that they (not Netgear push the firmware out). The last person I spoke with did say that there is no more TWC and they are in the process of moving everyone over to Spectrum (which they already did with my account). Since someone else on the forum confirmed that Comcast and Spectrum also merged, I suspect that is why they are using the Comcast firmware, although I am still waiting for a response from them to confirm that. It seems they obviously didn't work out all the bugs before they merged or transferred systems, but anyway, mine has been reliable and with faster Spectrum speeds for 6 days now since the reset. I did also do this after I received and email from TWC stating that my account is now Spectrum and with faster speeds. If the resets hasn't worked for some, maybe they need to confirm that Spectrum has transferred everything from TWC in their area and on their account. Not sure how all that works though.
