C7000 – Nighthawk AC1900 WiFi Cable Modem Router--Losing connection once a day requiring full reset
Hello,
I purchased my modem in August 2015 and it was working fine unitl June 2015 timeframe when I started experiencing minor connection issues (internet drops for few minutes). However, now it completely drops once a day and the only way to correct it is to unplug the modem from the power source and to reconnect it. I did submit a warranty form to NetGear, but no one contacted me back in June-July timeframe. I am very diappointed with this product, which I bought through Amazon and I think I should go back to give it a low ranking. Additionally, I can't even find the firmware for this product to reload it to see it that would fix it. One problem that I noticed was that the region is set for Europe and is greyed out, but the box does not indicate that it was a European version. Please assist if you can prior to my anger taking over with what appears to be an over-priced and underperformed Netgear product. Thanks
