My Canon wifi printer suddenly stopped working on my Xfinity wifi. Shows connected but offline

@XfinityJodie​ HI Jodie.  No I don't have access to my landlord's account and they are out of town for the next few weeks.  I have the Xfinity app for my home (the problem address here is a small office that I use so while I do have an account, it's at my home address).

Something I should mention is that when the problems began (Saturday July 1, 2023) I lost the internet connection here for about 30 minutes around noon.  It was a few hours after that when I tried to print and couldn't.  After a year + with the same printer, I wrongly assumed it was the printer.

I have multiple devices at my office here that use the Xfinity wifi with no problems.  2 laptops, a smart TV, my cell phones, a smart bulb, a Blink wireless camera, Amazon Fire TV stick, Amazon Echo, Amazon Fire Tablet.  Everything works except for the printers.

And since my new Canon wifi printer needs to connect to the internet to install the software suite, I have to find work-arounds to use the scanner, etc.  Even though it also has a USB corded connection, Windows 10 detects it but directs me to the Canon website to download the software and since it "can't find" my printer, the download fails.

We have an Xfinity router with both 2.4 Mhz and 5 Mhz and both have unique SSIDs and I can't connect to either and believe that the 2.4 is the only one that "should" work anyway.

My landlord said there have been no changes to the router (permissions or whatever) and has her own gripe with the wifi dropping out way too often.

They won't be back in town for about 2 weeks so if the router needs a reset, I'm stuck

Are you able to process the update through your other connection? 

If you mean have I tried taking my printer home and connecting to my home address Xfinity wifi in an attempt to at least get the Canon software to install on my laptop, then no.

While that may solve the issue of downloading the software, I'd still be unable to use it at my office address' wifi because the printer will likely still show as "offline" and that's where I need it to work.

While I've been dealing with sending back, re-ordering new printers, scouring the internet for help with this issue for 3 weeks, I was also dealing with non-stop issues with Xfinity's so-called support text, chat and phone ppl because I also moved on July 1  and needed to suspend my home internet account for a month while I waited for my new place to be ready to move in (didn't want to pay for a month if i couldn't use it) and the guy "John" instead canceled my internet account thereby triggering a $25 per line service fee on all 4 of my cell phone lines.  3 weeks of nonsense and that finally got corrected a few days ago, but it was another Xfinity nightmare being on the phone, etc for hours at a time only to have the problem made worse each time.

This printer issue of mine isn't unique.  There are hundreds of similar issues online that I found doing a quick search and NONE had a suitable resolution.  Something changed with this wifi 3 weeks ago that's causing this.  Maybe the modem just needs a reset, but I can't access it to find out and I don't want to bother my landlods while they're on vacation.

Can you do a reset remotely if I give you the account name and address or do you need their permission to do something that basic and simple?

I think my landlord's son is in the area.  If I can get him to come by, can I tell him how to reset the modem?  Is it as simple as unplugging it for a minute or 2 then plugging it back in?

Please let me know.  Thanks

@Peacemaker02324, Is the account in your name or in your landlord's name? If it is in their name, this would be why you are having a difficult time logging in. We don't want to share any personal information like an address in a public forum. Are you able to reach out to them and have them reach out to us? I'm just trying to think of the safest way to go about this for you and them. 

@Peacemaker02324, I understand your issue. It makes it difficult to troubleshoot since we cannot access the account. We would have to wait for your landlord to reach out. I am sorry about that. 

I understand.  I do have a follow-up question tho.  I don't have access to their home but i do have access to all of the circuit breakers located innthe cellar.

If I were to cut/turn off the power at the circuit breaker to the room in the house where the modem is, then wait a few minutes and turn the power back on to that room and modem, would that work as a modem reset?

Or would I risk the modem not turning itself back on without being physically at the modem to press the WPS button or whatever?

If I end up having to wait 2 weeks for my landlord's return to be able to print again, might this issue be caused by the "Advanced Security" feature for the wifi?

At this point I'll take your best guess

@Peacemaker02324, I would not want to give you any advice on this either way. I am sorry about that.
