I have recently been having ping spikes over 5Ghz wifi (no problems on 2.4 GHz), they happen at night after 5pm and I get one approximately every 30 seconds, they are also in groups with 1 minute intervals (see picture).

I have checked for interference using inSSIDer and I have set the channel so that it is in the middle (see picture).

I have no devices in the house that operate on the 5GHz Frequency.

Router: Huawei HG659b (isp supplied: Spark NZ)

Does anyone have any ideas on how to fix this problem or what might be causing it.

Thanks

I have standard house lights on, but this issue has only started within the last few weeks, it worked fine before and I haven't changed anything in the house.
