Poor WiFi performance

[scotts9219]

Lately I have noticed extremely poor throughput on WiFi. Running Ookla's Speedtest app gets .29Mb down and almost 2Mb up. I forgot the network settings for the local network and reinstalled it with no success. Testing with a laptop and an iPhone 6 gets 16Mb down. Anyone have any ideas?

It's possible you have a signal interference problem. You need to determine the best setup for your situation and configure the router and phone accordingly. To find the best setup try using WiFi Overview 360. The free version is probably all you need but the Pro version is cheap.

On dual band routers give the 5GHz and 2.4 GHz bands different SSID names. When setting up the 5GHz band usually it's best to set the router to use a channel well over 100. Over 150 if there's a clear channel. For both bands of course use channels with the least interference and best signal as indicated by WiFi Overview 360.

It could also be the TKIP problem. Set the router's encryption to AES, not TKIP or TKIP+AES. (You'll have to forget the connection, then connect again. And all other devices will have to be reconnected.) Also turn off IPv6 if your router has it.

An interference problem would affect both phones if they're at the same place.

I don't think TKIP or IPV6 apply in this case. The speeds he's getting are kinda poor with an Android, and worse on an iPhone and a laptop. But the OP said he's only noticed slowness lately. If it were TKIP or IPV6 it's unlikely to have started causing trouble out of the blue and on 3 very different devices.

No, if TKIP or IPV6 were responsible there would have been trouble all along - unless, of course, the TKIP and/or IPV6 settings have been changed lately. There's no mention of any changes to his network.

More likely the network environment has changed. Other surrounding networks were added or modified, microwave ovens, electric motors, any number of external factors might have been changed in some way.

So IMHO the OP should do some sniffing around the airways and see if that turns up the trouble. And I suppose it wouldn't actually hurt anything to fiddle with TKIP and IPV6. I've been wrong before. Just be careful and have backups.

Just to clarify, the laptop and iPhone are working correctly. They both are getting good numbers for network speeds. I have several devices on that network with no problems. The problem is isolated to my phone. I also noticed it has problems at other locations. I turned off switching between 5GHz and 2.4GHz to see if that helps (it didn't). I'm trying to eliminate as much as I can before going back to factory default.

I ended up doing a factory reset on the phone. Cleaned up my problem and looks like it might have cleared up other little problems. The last upgrade must not have gone as well as I originally thought.

Anyway, thanks for the ideas. Always appreciated.
