nslookup is fast (including for addresses I’ve not looked up before) and ping is fast (~10ms) to a range of addresses. curl google.com can take two minutes to return anything, but once established connections seem to give fast download speeds.

This is on a home Wi-Fi network (Compal CH7485E model router, 2.4 and 5 GHz, 802.11b/g/n), affects some devices (Mac OS X, Android phone) but not others (Windows, Linux laptops), and seems not to be affected by a choice of Wi-Fi channel or frequency. Changing DNS servers, e.g. to Google DNS, doesn’t help. Wired connections seem to be fine.

What could cause such behaviour?

    Please edit your question to add some more details. Such as the exact make and model of the Wi-Fi router you are using. – Giacomo1968 Oct 26 '15 at 12:17

    While I'm with @JakeGould here, if I'd have to guess w/o more information, I'd first check the WiFi standards supported by all devices. If your Mac and Android only support older standards than the other WiFi participants, it could be that the root cause is the way your router handles WiFi clients which support different standards. – Run CMD Oct 26 '15 at 13:28

    @ClassStacker Agreed. The issue could be something as simple as the devices that are working well are connecting via 802.11ac while the rest of the devices that are acting sluggish are connecting via 802.11n. This might make this question a [possible duplicate of this other question](http://superuser.com/q/898583/167207). [My answer on how 802.11n is a horrible spec says it all](http://superuser.com/a/898595/167207): 802.11n is horrible and issues like this are par for the course in man 802.11n setups. – Giacomo1968 Oct 26 '15 at 14:00

    @JakeGould thanks for those links. I'll try tweaking for that, and I'll be delighted to close as a duplicate if it works. – Joe Kearney Oct 26 '15 at 14:05
  • @JoeKearney Well, please read my answer there: The one big “tweak” one can really make when dealing with 802.11n nonsense is to get an 802.11ac adapter or a new device. It’s just horrible. But maybe an idea would be to see how problematic devices behave when connected at 802.11g? The 54Mbps speed might seem slow for a LAN but honestly that is as fast—or faster—than most home Internet connections. – Giacomo1968 Oct 26 '15 at 14:08

    That's actually whatI meant, I'll try dropping everything to 802.11g. – Joe Kearney Oct 26 '15 at 14:10

It's the normal behavior for this device. Unless there will be a firmware update, you just have to accept it or get your own device.
