A customer called stating that several arc fault breakers began tripping. I asked if anything had changed recently. She had just changed over to X-Finity for her internet service. I mentioned the possibility of interference from some electronic devices. I asked her to unplug the router and the tripping stopped.
Is there any sort of filter this modem can be plugged into to prevent tripping? Seems an unnecessary expense to try replacing breakers. This is a Siemens panel. House is no more than 10 years old.

I do appreciate any feedback

I must make an addendum to my initial post. I have just arrived at the customers home and it turns out that they did not unplug the Xfinity box. They had purchased wireless extenders. When they unplugged them the tripping stopped. Again, I ask are there any type of filters that can be used to prevent tripping?
 
take a short #18ga extension cord (3-4ft) and wrap that around a piece or iron (rebar or the like) then tape over the winding. using a iron ring is better, but try just a piece/length of iron, plug in each end, see if that helps. wrap the whole thing over about 3" length, it will make layers.

are they 2.4 and 5GHz extenders, or just 2.4 or just 5GHz ?
make/model of extenders ?

side note: why is there noise on the wires? poor device filtering, thats why. its like when your cell phone is communicating and you put it near a cordless phone that is in use you can hear the buzzing and clicking in the cordless phone.

so basically its interference and gfi agfi's are reacting to that noise on the wires. i think that is bad if they are UL listed.

Those extenders should have an FCC sticker on them stating they are Part 15 devices. Part 15 devices must NOT produce harmful interference. Since they are, they should be replaced and, if it were me, a complaint should be filed with the FCC.

Here is a sample of such sticker:

From Wiki:

Code of Federal Regulations, Title 47, Part 15 (47 CFR 15) is an oft-quoted part of Federal Communications Commission (FCC) rules and regulations regarding unlicensedtransmissions. It is a part of Title 47 of the Code of Federal Regulations (CFR), and regulates everything from spurious emissions to unlicensed low-power broadcasting. Nearly every electronics device sold inside the United States radiates unintentional emissions, and must be reviewed to comply with Part 15 before it can be advertised or sold in the US market.
 
These sound like powerline extenders that send the signal over the existing 120 volt branch circuit conductors.
 
If the house is 10 years old, why are there AFCI breakers?

??
10yr old homes were installing afci's, maybe as an upsell or some bs like that?
my own house is 10yrs old and has some afci's (ocpd's).
