Hey all! Canadian here, on TekSavvy (uses Bell Canada's lines).

I'm in a subdivision, not a rural area and I'm not far from the transfer station. I'm on an ADSL2 service, 10mbps down, 1mbps up. Using a SmartRG SR505N in Bridge Mode as a modem, and a TP-Link C1900 as a wireless access point. The TP-Link is handling the PPPOE authentication.

The internet is driving me crazy. I used to run a TP-Link modem-router combo device, and about half the uptime was spent with ludicrous pings (>1000ms) and dead speeds, both wired and 2.4GHz wireless. Had to reboot it multiple times daily, many times, and it only worked for a short while. We figured it was the modem, due to some troubleshooting...so, we replaced it with the aforementioned hardware.

The issue has returned. Wired, 5GHz and 2.4GHz connections all are facing pings of 2500ms at times. It's intermittent, but still - absolutely terrible. Can't use the internet half the time. It drops after an access point reset, and letting it sit for about 5 minutes after the reset, but then it'll come back.

I ran a ping from various computers (homebuilt desktops, a Surface Pro 4), and also from the AP itself. They're all similar (2000ms+). I also ran a traceroute from the AP when the issue was occurring, but I didn't see anything out of the ordinary...don't know much about traceroutes.

There are 4 devices wired into the AP - a desktop, an HDHomeRun dual TV-tuner hooked up to antennas, a VOIP box, and the modem. I'm at my wits end. The entire family is. We don't know what to do. The goal is to eventually switch to VDSL 15/10 connection, but if this issue is internal then we'll never see any benefits anyway. Any help would be greatly appreciated...

Best regards,
Colton

Yeah, and they go through some configuration suggestions, get us to reboot the devices, and then the issue goes away, and we hang up, then it comes back.

We purchased all the hardware separate from the ISP, though. I don't know if the ISP is at fault here, I really have no idea - there's so many configuration options in a router or modem, networking is the one aspect of computing that really eludes me...I'm thinking the configuration or hardware is at fault, but I really have no idea on how to troubleshoot this.
