Good morning from Canada! I'm having issues with my internet connection and was hoping for some advice from all of you at Tom's Hardware forums. I have internet with Shaw Cable in Canada. My internet connection is 1GB down and 100Mb up.
I have my Bluecurve modem (model is Arris TG3482ER3) in bridge mode. Directly connected to it is a Unifi USG-3P router running firmware 2.4.8. From their it connects directly to a USW-FLEX-Mini smart switch. From their I have multiple branching devices. Directly connected to first switch is my PC which uses a ethernet cable to plug into the switch. Also on same switch is a second identical switch. On the first switch the second device a UCK-G2-Plus (That is a unifi cloud key gen2) which controls the network and sets up the devices and updates firmware etc. The router has no custom configuration and has dhcp for both WAN and LAN on default. As configured IPV6 is disabled as it requires custom configuration and I had reset router and not done anything beyond set up wifi. I had a sweet custom configuration with separate VLANS for IOT devices etc but turned that all off for ease of testing out this problem.
Randomly the router loses connection to the internet and shows as having no DHCP lease. The internet goes down for about 4 to 5 min at a time. This happens randomly and can happen multiple times a day then not happen for weeks. Its an intermittent problem. The wan interface shows 0.0.0.0 and says no connectivity.
After talking to Shaw they indicated the modem was working and had a good signal. They said there was nothing wrong. The first thing they told me to do was reboot the modem. I had tried that but went through the procedure again with them on the phone. They said the logs they had access to indicated the modem had been running fine for months. I have called back complaining many times with them now telling me to disable bridge mode and use the modem as my primary internet to try and troubleshoot the issue. I have replaced the ethernet cables with new ones bought recently as a further troubleshooting method.
I have tried running Ping plotter which did catch the device when internet stopped working. It showed my ping to google as being about 1500ms and the connection stops somewhere in a google data center and never gets to google.com. At this time the router shows 0.0.0.0 and no IP and no DNS. I assume I lose the lease and it takes modem 5 minutes or so to give me a new one? I have tried doing hard reset on modem and all connected network devices and updating the firmware on devices. I never lose local access to router its only the WAN that goes down. The light for ethernet port on modem and router are lit up just fine so they are talking to each other but no joy! I can ping the router but have no access to modem while it is in bridge mode. The suggestion to just stop using my third party hardware and my problems will go away is sort of really making me mad.
I don't believe the hardware I have is faulty. I could be wrong. I do not have another router to check if issues persists. I originally bought the unifi hardware because the wifi with shaw was crappy and did not even go halfway down my driveway. Now it goes down the road. Also I could not set the router to use google or cloudflare DNS and it was locked to ISP DNS. I'm pretty sure if I disable bridge mode and just use the ISP equipment all of my problems will go away. But I will lose the ability to control DNS unless i configure it device by device. Also I can't set up VLANS or do a bunch of other things I want to do. Any suggestions to intermittent issues with DHCP lease being lost and taking 5 min to get one back for my router would be appreciated.
Upon further inspection I lose my DHCP lease every 1 hour and 10 min. It takes about 5 minutes for the lease to be given to my router. While that is happening the internet is of course down hard.
