bufferbloat and router
I have a severe, intermittent latency problem which netalyzer suggests is probably due to buffer bloat in the router. Are there any suggestions? Perhaps a wired router with smaller buffers? Recycling the router helps sometimes but not always.

I had that.
The trouble in my case was that the broadband was being "upgraded." Coming in 3 km (2 miles) on a phone line I had first 2Mbit, then 3, then more. The line was good for 2Mbit. I ended up with a lowest connect speed of 2.3Mbit which went on and off like you describe. There's error checking in most routers - check it out. I ended up with the following choices 1. Continue paying for crap service. 2. Switch back to the more expensive isp attached to the phone company who owned my line in the hope they would fix it. 3. Do something else. I chose 3, and never looked back. On principle, I wouldn't do 2. |
Already checked that. It's not the problem.

The isp says it's not their fault.

Which ISP are we talking? Many ISPs will claim it isn't their fault in the hopes you'll believe them, regardless of truth behind it.

The isp is speakeasy/megapath. Their tech ran a check and it came out all right. The various on line dsl tests come out all right, yet pages often take forever to load. Not always. I found netalyzer through a link at wired .com, if I remember correctly. Sorry if I left anything out. It seemed to me that I had only one question.
