I have 100Mbps Download speed and 2-3Mbps Upload speed.
HOTnet(ITC) is my ISP.
My router is TP-Link TL-WR940N.
I need to replace my modem because my modem is broken.
Is it ok to get a cheap modem like this https://www.amazon.com/dp/B01CH8ZNJ0/?
If i will get this modem https://www.amazon.com/dp/B016PE1X5K, will it be faster, handle more packets, better bandwidth or lower latency?
Oh and i need to know if those modems are compatible with my ISP(My ISP uses DOCSIS 3.0).

Everybody please i need your help, even though people already suggested, suggest too, do not ignore because people already replied, i'm still not sure.

The higher speed modems just support more simultaneous bands. Your ISP's communication with your modem (and vice versa) is spread among several frequency bands called channels. Most DOCSIS 3.0 modems support 8x4 or 16x4 channels. The TP-Link modem you've linked supports 8x4. The Arris 6190 you've linked supports 32x8.

Each channel will get you about 40 Mbps of nominal bandwidth, or about 20-30 Mbps in real-world use (due to noise and distance). So the TP-Link should be good up to about 160-200 Mbps down, 80-100 Mbps up. You only need the Arris 6190 if you want to exceed 1 Gbps down, 200 Mbps up.

Unless you're planning to upgrade to the higher speed service in the near future, I'd just get the cheaper one. The only thing to...

A higher grade modem is never a bad idea. However, the core of your internet speeds are going to be based on what you actually pay for. Not the modem. Normally ISP provided modems are good enough to provide the speeds you purchased. You will not get increased speeds over what you purchased by simply swapping out the modem.

Now if you are having internet issues where packets are being dropped or you are not getting the speeds you paid for. Then a modem replacement might be a good ideal.

You need to speak to your ISP about what modems are compatible. Some ISPs even replace it for free if you ask. (I know Specturm does this) Some ISP's wont accept 3rd part modems and others simply have restrict modems that are compatible on their network.

My current modem is dead now so i need another modem, for 100Mbps downstream, is there any difference between tp link(The amazon link i posted) and arris(The amazon link i posted), is there any reason to get arris and not tp-link or it does not matters because my internet speed only 100Mbps and cant reach any of them?

I would suggest an Arris. Here Specturm (use to be Bright House) mainly uses Arris modems. They are pretty reliable. I would recommend you look for a one step higher Arris modem that can handle the full speeds you get from your ISP.

However, I would get the modem number and call your ISP to make sure its compatible before you purchase it.

Is there any difference between the two modems?
Are you sure the arris will be better than the tp link even though i will never reach any of those speeds?
A one step higher arris modem will be DOCSIS 3.1, which is not necessary cuz i dont think my isp supports DOCSIS 3.1

The only thing to worry about is quality since it's a little-known brand (for cable modems). There's also an Arris/Motorola 6183 which is probably the most popular DOCSIS 3.0 modem in use today - 16x4 channels. I've seen it occasionally go on sale for about $50.
