Re: BT Infinity with Cisco Umbrella (OpenDNS)

Go to solution

Appologies Keith, I got this mixed up with another router I ordered some months ago. This query is related to the TP-Link TD-W9970. I couldn't recall the product name and searched my email and obviously pulled the wrong one out of the hat.

Dave,

The default wireless settings on the W9970 is automatic channel selection. Its quite possible its either switching channels, or there is interference on the wireless channel its using.

 

Its best to select a channel manually, channel 13 is usually quite good, or you can use a wifi app to find the clearest channel where your computer is located.

 

The sudden drop in signal quality is most likely interference, or the TP link changing channel itself.

Thanks Keith. I will change it and report back. Incidentally, isn't channels 1, 6 and 11 the norm?

 

Looking at the log, it's dropping out every 15 minutes regular as clock work. Strange.

The channels 1,6 and 11  which is often quoted, is a mis-conception, and is very misleading, which is why those three channels are always congested, and why people get dropouts on wireless.

 

1,6, and 11 are simply those which do not overlap each other. So if you had three wireless access points in your house, then spacing them on those channels would mean they would not interfere with each other.

 

There are 13 channels available, I am using channel 5 at the moment, as it has nobody on it.

 

I assume that Ethernet connections are not dropping?

 

If you think its DHCP renewals, you can reserve the IP address on the DHCP page. I see those on my guest network, from an iMac that my neighbour uses, but it does not affect the wireless connection.

This is what I see, but it does not cause any disconnections. The ones in bold are the IMac

Thanks Keith.

 

The DHCP messages have stopped since fixing the channel. I've not been on the phone much this afternoon so can't verify that's working now as well. I will let you know.

Then that may have been the cause, interference on the channel. I have never used auto settings on any router or wireless access point, I always manually select the best channel. Avoiding those common three channels, has always worked.
