Arris G34 wifi going out but showing I have good connection with blue light still on.

We apologize for the inconvenience caused by the non-functional link. Could you please specify which link you attempted to access?

Could you provide the name of your internet service provider and the speed plan you are subscribed to?

Does the internet drop occur only on Wi-Fi, or does it affect the hardwired connection as well?

If the issue is only to Wi-Fi, then make sure that the G34 router is placed in an open area to avoid Wi-Fi congestion, which can lead to internet drops.

Does the internet drop affect only a specific device, or does it impact all devices?

My ISP is Cox and I have 1gb speed plan. I only use wifi so don’t know if its affecting hardwired connection. The interenet drops affects all devices. 

This is the link I was trying to acess http://arris.force.com/consumers/articles/General_FAQs/G34-G36-Cable-Signal-Levels. It seems like all the link I try on here don’t work though. 

I’m having the same issue. G34 modem router. Blue light is on and solid but no internet? I’m in Hampton Roads Virginia if that matters.

Since you're experiencing intermittent issues over the wireless connection, I recommend changing the Wi-Fi channels to reduce wifi congestion and monitoring the performance over the next 24 hours.

Have you activated the modem with your ISP?

Can you confirm if the Wi-Fi network is visible on your devices?

Have you already tried basic troubleshooting steps like power cycling the modem or performing a factory reset?
