Do I need a router? 

Wonderful. Thanks for saying HI

Thanks Raynell. Appreciate the feedback. Thanks for watching. 🙂

Thanks for the feedback 😊

I’ll take that compliment 😊

Thanks Mr. P. Yes wifi is either built-in to the Router. Or, if you use an external Wifi antenna (formally called an Access Point or AP) then it will connect to one if the switch ports. In a rough sense, you can think of an AP as a wireless switch. Hope that helps. 😊

AMEN

If you truly only use one device, then you can get away with not having a modem. It's does raise some security concerns in my mind. But, if what you have is working for you then no need to mess with it. 🙂

Yes, I could fill in for Bob Odenkirk for voice-overs. 😆

If you have one device a modem is enough

Thanks for letting me know.😊

Andrejs, that's a great suggestion. Your assertion about cross-over cables is true. But in recent years it is less required to use a cross-over cable because the switches (even the dumb ones) now have an auto-sensing process to know if they are connecting to another switch or a host device. So, even if you connect two switches with a straight cable, it will most likely still work. But in any case a video on the process of adding multiple switches would be a good topic! 😊

Thank you for the feedback. :-D

So glad to hear that helps!

yes, you can do that. And, as long as you're ok with your computer being DIRECTLY on the internet with a public IP address, it does work. There are even some cases where you might want that - Gaming for instance (I'm not a gamer, but I'm just guessing) Thanks for asking that question. I'm sure others have wondered that too! :-)

@@NetworkAdvisor Cool thanks for your reply. You got some great informational videos. I always learn something new or I reinforce some previous knowledge by putting it into a different context. So thanks!

This was a great question, thanks for asking and thanks to Network Advisor for answering. Most informative .

You'd still need a router with wifi if you want to connect to the internet on your phone, though.

@@NetworkAdvisor is that dangerous ?

If the modem only has one port, then it's very likely it is only going to allow you one public IP address. I'm assuming if you have a switch it's because you have more than one network device. So, you need a router to convert that one public IP address into a private subnet so multiple devices can share that connection.

ahaha.. yeah.. just get one - they're only $25. :-D

Yes: that is what I meant. Or, in some cases - modem/router/switch. Thanks for bringing that up. 😄

@@NetworkAdvisor That really helps. I bet 19 out of 20 people do not know the difference in these devises.

If your internet modem only has one port, then you must use a router if you intend to use more that one device to access the net. But, some modems come with a router built in. In that case you will usually see 4 ports. The reason you need a router is that you ISP only gives one IP address. The router is what allows several devices to share that one IP address.

@@NetworkAdvisor Oh! Now I understood. Thank you so much for responding. Here switch create subnet ip from the router ip and gives many lan connections. Understood....

The simple answer is NO. The router treats all those ports as equal and will randomly assign IP addresses from a pool regardless of which port the machine is connected too. Now, a more complicated answer is that in commercial-grade routers and switches you can force IPs to a specific port. But since I assume you're probably asking in the context of a home or small business setting, then my first answer probably applies. Good question, BTW. 🙂

@@NetworkAdvisor thank you

Yes Alex , most modern, consumer-grade routers come with those 4-in-row switch ports built in. So if that’s enough, then you don’t need another external switch. 😊

And just to be extra clear. Most commercial, enterprise-level routers would almost never have that, so a switch(es) would definitely be required.

@@NetworkAdvisor sweet, thank you very much. I’m new to all this 👍

Generally, your internet provider gives you (or rents to you) a modem. And more often these days, the modem includes a built in router and switch.

yes, router is still needed (wired or wifi) if you plant to use more than one computer in the local area network.

That won't work: connecting a switch to the modem. The reason is that you typically only get 1 public IP address from your ISP. If you plug multiple devices to the switch (which in turn is plugged into the modem), the first device will get a public IP and not the other ones. A router allows you to share a single public IP address with multiple devices within the LAN (local area network).

@@JJFlores197 Thanks Jose. I believe my Motorola MG7550 is a combined Router-Modem. I will make sure before adding a switch to the system.

Here in the US, most of the internet providers will loan you a modem/router/switch combination unit. But, depending on your needs and how sophisticated you are, you may want your own router. 😊

@@NetworkAdvisor Right click the video -> "stats for nerds", next to "Current / optimal res" you'll see "1920x1080@15". You can also see the video is pretty jerky. Thing is, audio quality is SO MUCH MORE important than video quality, so you can get away with it.

ok.. let me check that out. I'm using a new camera (where I used to use a smart phone before). It's a Panasonic VX981. Thanks for the 411.

Glad I can help. 😄

Yes, I have heard that frequently ☺

11 11 if you didn’t use a router and it went straight from your modem to your pc would it make the speed any faster?

11 11 thank you bro.

I'm looking for a solution for the bandwidth loss due to use of several switch/routers. can you help please

Glad the information was helpful 😊
