My ISP insisted that my slow download speeds are due to my third party router. This is BS, right? (alien.top)

I live in Canada, and my ISP is Telus. I'm subscribed to their gigabit plan.

However, I only ever really get 250mbps. This is adequate, but I'd like to get closer to the speeds I'm paying for.

I get that peak times might have slower speeds, but I can do a speed test at 3am and it's the same. Hell, even if I was getting 750 I'd be happy.

Called Telus up, and the only thing the guy would say is its because I have a third party router and not their own. I have a TP-Link Archer C7 with openwrt. It's a gigabit router. My PC is connected to this via a gigabit switch.

My ISP does allow third party routers, I've been using it for years before upgrading to gigabit.

On the plus side they're sending out their newest router for free so I could at least give them the benefit of the doubt, but I'm suspecting I'm gonna get exactly the same speeds more or less.

The guy kept touting its "wifi capability", even though I don't use wifi for anything except cellphones. All my heavy downloads are on wired devices.

So am I correct in that the guy is talking out of his ass and I'm likely stuck on a 2 year term paying $30 more than I should be?

I ran archer A7( same as C7) with openWRT before. While the ports are capable of gigabit speed, its processor is not up to a task routing a gigabit internet. I was getting around 200mbps through wifi.

I suggest to test on your ONT whether you are getting a gigabit speed as promised.

This ^^.

I was having similar problems with a TP-Link C9. Tested with iperf

PC->router->PC, wired

iperf indicated that the C9 topped out at 432 Mbps. Other than a static IP address on the WAN port, the C9 was in the default config.

Update: I tested at the ONT - speeds are marginally better (about 100mbps more) but still nowhere near gigabit.

You're not going to get gigabit out of the C7 unless you use stock firmware, if even then. Stock firmware can use hardware offloading that openwrt can't, though it has some. Get a more powerful router.

Not using wifi, I know wifi speeds are slower. This is on wired.

I will try testing at the ont though

[–] [email protected] 1 points 11 months ago

The trouble is you need to enable flow offloading in LUCI, I believe it's under the firewall settings or else you'll be pretty speed limited regardless of wired or wireless. I believe the default for the C7 is to have it turned off.

hi ballisticks,

out of curiousity i pulled of my C7 and installed the latest openwrt (23.05.2).

With software offloading through ethernet im getting around 200mbps.

Some people built openwrt with QCA specific feature enabled hitting 900mbps, but that was a long way back then.

Let me know if you found a good build.

Jumping on here as well to say Yes, I have also encountered this. The ISP could be correct but OP will want to test and validate this.
