Problems with unstable internet (hardware problems)
Problems with unstable internet (hardware problems)
When I launch Chrome, it claims no internet connection right away, then reconnects after a short delay. During gameplay in Magic Arena, launching the app causes intermittent failures—forcing me to close and reopen it before it stabilizes. Once connected, everything performs smoothly with fast speeds of 1000Mbps upload and download. After watching today’s video, I wondered if the issue stems from my Netgear GS-108 or perhaps the cable length in my walls. My home office is where I play games, but my modem, router, fiber optics, etc., are located in a closet upstairs. I use an ATT modem connected to the same Netgear GS-108 that supplies internet through the panel in my house. In my office, I have a Nighthawk R8000P connected via Ethernet through the wall, which is also linked to my desktop over Ethernet. If you need more details, I’ve been trying to solve this on my own without success.
Get the switch to split the internet across every room, so you can pick a direct connection to the modem rather than using Wi-Fi.
This setup links all areas via the switch, with the modem connected through it. Your office uses a router connected to the same switch, and your computer is linked to the router.
There are 8 Ethernet ports in the house, all connecting to a switch. I placed the router in my office for improved coverage and used the modem they supplied, which isn’t ideal. I’m aiming for MIMO performance. With only one port in the office, sending traffic directly to the router and then to the computer seems reasonable. Would it be better to route from Modem → Router → switch instead?
A modem functions as a connection point, so labeling it a "bad router" is misleading. Pairing two routers isn't advisable unless you set them up properly; otherwise, connection problems are common. If you can switch the device to bridge mode, connect your router straight to the modem and then the router to the switch. Set the router for PPPoE and adjust other settings as needed. Without bridge mode support, consider a different device that offers this feature so your router can sit behind it. For IPv6, ensure your router supports prefix delegation if you need it. You might not require the original device at all—your router could suffice instead. If you avoid using the router entirely, issues should disappear. The current wiring likely routes every client through the switch and then the modem; connecting the router directly after switching it on usually creates problems. What you should aim for is linking the router directly to the modem once in bridge mode, with the router connected to the switch, or ideally, skip the device and connect the router directly to the internet while configuring the switch accordingly.
Thank you for your follow-up. The issue is that Bridged mode isn't supported on the AT&T platform since they need 802.1x authentication from all gateways. It seems like testing might be limited, but MUMIMO appears to help. You may want to remove the router from consideration or proceed with the recommended steps.
Is there a connection available? Without the proper setup, linking the router might lead to issues, such as both the router and the faulty modem assigning IP addresses to clients. You likely won't succeed with IPv6 unless the problematic modem supports it. AT&T should follow established standards rather than using proprietary solutions, ensuring customers can use their own devices. If they hadn't mentioned this earlier, I would contact them and, if they decline, reduce their charges until they comply.
Removing the router fully resolved the issue for me. Appreciate the assistance! I also purchased a second switch for my office to act as a repeater for longer distances. Now I have four devices requiring a wired connection, and it's all working smoothly. Thank you so much!
