Imgur images take too long to donwload

Question

Short description

Recently my ISP changed my modem/router and I'm experiencing now slow downloads in some sites (imgur.com, tenor.com for example), that worked fine with my previous router. I'm not sure if there is something wrong with my router's configuration or it's an ISP problem, and they would not be of any help providing me information.

More Information

I'm not sure what kind of information is useful in these situations, but these are some things that I noticed.

My internet connection plan is 25 Mbps download and 3 Mbps upload, and I verified this through fast.com and speedtest.net though sometimes it's slower, but generally it's high even when measured at the time when the aforementioned problem happens.

Ping is usually 10ms (stackoverflow.com) but for i.imgur.com it's ~ 160ms

I'm not sure what kind of method imgur uses to download images but I noticed that even small images takes too long to download.

Here's a Chrome "Network" panel screenshot:

I did also try using a VPN with same results.

Edit

I moved my answer here since it was not the solution. My ISP sent a technician to my home. He looked at the modem/router and said it was ok, and then reviewed the street box and said there was a problem there (he didn't give me too much detail and I'm not an expert) and that they'll be fixing it in the following days. Apparently there was too much signal noise which was causing a lot of packet loss. The next day I came home and noticed that the problem was gone. I verified that the ping and tracert values were still the same but I could navigate normally. After I couple of days the problem slowly come back, so I'll be reporting back to them.
