Marka aad iska diiwaan geliso adeeg internet oo cusub, waxa laga yaabaa in lagu siiyo modem iyo router ama hal qalab oo labada shaqo qabta. Runtii ma u baahan tahay inaad hesho modem iyo^{(and )} router si aad u isticmaasho intarneedka? Waa waqtigii la nadiifin lahaa dhowr fikradood oo khaldan.

Nadiifinta Macnaha "Modem"

Erayga "modem" waxa uu u soo gaabiyaa modulator/modulator. Waxa loola jeedaa aaladda loo isticmaalo in lagu dial-up internet , halkaas oo xogta lagu diro iyada oo la isticmaalayo khadadka taleefoonada naxaasta ah ee codadka la isticmaalo.

Modemku waxa uu qaadaa kuwa iyo eber ka ee u taagan baakidhka xogta laga soo diray intarneedka waxana uu u rogaa dhawaqyo dhawaq ah oo ka kor mara silig naxaas ah. Waxa kale oo ay samaysaa rogaal celis, iyada oo dhegaysata dhawaaqyada ka imanaya intarneedka oo ay dib ugu celiso koodka binary.

Modemyada casriga ah ee loo isticmaalo DSL , fiber, cable, iyo mobile data maaha modem marka la eego ereyga asal ahaan. Si kastaba ha ahaatee, waxa ay ka siman yihiin ayaa ah in xogta dhijitaalka ah ee kombiyuutarka laga beddelo qaabka habka gudbinta-tusaale ahaan, u beddelashada dareenka korantada ee garaaca iftiinka ee loo isticmaalo fiber optics.

Waxa ugu muhiimsan ee ay tahay inaad ogaato waa in modemku yahay aalad kugu xidhaysa internetka weyn. Waa meesha looga gudbayo LAN^(LAN) gurigaaga ( Shabakadda Aagga Maxalliga ah^{(Local Area Network)} ) ilaa WAN ( Shabakadda Aagga Weyn^{(Wide Area Network)} ).

Waa maxay "Router"?

Xogta shabakadu^(Network) waxay gasho oo ka baxdaa gurigaaga ama meheraddaada iyada oo loo marayo modem-ka. Weli, waa router u habeeya taraafikada shabakadda ee aalad kasta oo gaar ah, labadaba midba midka kale ee shabakadda gudaha iyo inta u dhexeysa aaladahaas iyo internetka.

Shaqada router-ku waa dhib badan tahay, qalabkanina asal ahaan waa kombiyuutaro u gaar ah oo leh CPU , xusuusta, iyo nidaamka hawlgalka. Waxaad ku xidhi kartaa furayaasha shabakadaha, PC-yada, taleefannada casriga ah, iyo aalad kasta oo Wi-Fi ama Ethernet ah router-ka, waxayna ogaan doontaa meesha laga diro xirmo kasta. Routers, ugu yaraan kuwa ka qaalisan, ayaa sidoo kale socodsiin kara codsiyada shabakada. Tusaale ahaan, waxay u dhaqmi kartaa sidii qalab VPN ah ama waxay maamuli kartaa kaydinta shabakada ku xidhan.

Inta badan router-yada waxay bixiyaan ugu yaraan afar dekedood oo Ethernet ah iyo ^(Ethernet)Wi-Fi , oo awood u leh inay isku xiraan oo maamulaan daraasiin ama xitaa boqolaal qalab. Haddii aadan run ahaantii haysan hal qalab oo kaliya oo aad rabto inaad ku xidho internetka adoo isticmaalaya modem, waxaad u baahan doontaa nooc ka mid ah router.

Fiber Vs. DSL Vs. Cable Vs. Modems-yada gacanta^{(Fiber Vs. DSL Vs. Cable Vs. Cellular Modems)}

In kasta oo aalado badan ay wadaagaan summada “modem,” lama beddeli karo. Inta badan modems-yada guryaha waxay leeyihiin deked Ethernet ah oo ku taal dhinacaaga isku xirka, laakiin aad bay uga duwan yihiin dhinaca internetka.  Moodeemka Fiber -ku waxa uu ku xidhaa xidhiidhka fiber-ka, ^(Fiber)DSL waxa uu ku xidhaa siligga talefoonka naxaasta ah, modem-ka xadhiga waxa uu ku xidhaa fiilooyinka TV-ga coaxial, iyo modem-ka gacanta waxa ay isticmaalaan calaamadaha raadiyaha microwave-ka.

Marka, macnaha guud, jawaabta "ma u baahanahay modem?" waa "haa" haddii aad ka guureyso nooc xiriir ah oo aad u guureyso mid kale. Modem-kaagii hore ee DSL kuma shaqayn doono isku xirka fiber-ka ama fiilada, tusaale ahaan.

Mararka qaarkood Modem-ku waa^{(Modem Is Already)} uu jiraa

Haddii aad u soo guurto guri dabaq ah ama guri uu ka jiro isku xirka "fiber", waxa laga yaabaa inaad hesho deked Ethernet duug ah, oo aad ku xidhi karto router kasta oo leh deked "WAN" ethernet ah. Si kale haddii loo dhigo, uma baahnid inaad iibsato modem sababtoo ah mar hore ayaa la rakibay.

Tani waxay si gaar ah run u tahay kiiska fiber-ka. Dadku waxay u maleynayaan "modem-ka fiber-ka" sida router-ka ethernet-ka ee ku xira ONT^(ONTs) -yada ( Terminals Network Optical^{(Optical Network Terminals)} ). Taasi waa aaladda u beddeleysa calaamadaha korantada ee Ethernet una beddela garaaca iftiinka.

Jidadka Fiber^(Fiber) -ka ayaa sidaas darteed kaliya router joogto ah, laakiin sida caadiga ah waxay taageero u leeyihiin heerarka Ethernet ee degdega ah. Ka dib oo dhan, haddii aad leedahay fiber gigabit ah laakiin aad ku xidho router taageera 100Mbps ethernet kaliya, waxaad luminaysaa 90% xawaaraha buuxa ee khadkaaga internetka!

Haddii uu jiro qalab leh hal ama laba dekedood oo Ethernet ah oo aan lahayn ^(Ethernet)Wi-Fi , waxay u badan tahay inaad eegayso modem kaas oo aad ku xidhi karto router si aad u balaariso shaqadiisa.

Faa'iidooyinka iyo khasaaraha^(Pros) ee All ^(Cons)-In-One^(All-In-One) Aaladaha

Haddii aad u baahan tahay modem nooca xidhiidhkaaga ah, maadaama mid aanu ku jirin qorshaha ISP -ga ama aanu horeba loo rakibin, waxaad soo iibsan kartaa qalab isku-dhafan oo ay ku jiraan labadaba modem nooca broadband ka ah iyo Ethernet iyo Wi-Fi router.

Waxa kaliya oo aad u baahan tahay unug dhan-in-hal sidan oo kale ah haddii aadan hore u haysan modem, laakiin haddii aad u baahan tahay modem, waxaa jira faa'iidooyin yar (iyo faa'iido darrooyin) inaad u socoto hal qalab oo wax walba sameeya.

Dhinaca togan ee isla'egta:

• Badanaa way ka jaban tahay laba qalab oo kala duwan.
• Kaliya waa inaad wax ka qabato hal hab oo dejin midaysan.
• Cilad-raadinta way fududahay maadaama ay jiraan qalab kala duwan oo yar oo ku lug leh.

Dhinaca aan-si- togan ee isla'egta:

• Haddii qalabku xumaado, ma lihid internet. Iyada oo modem gaar ah, waxaad weli ku xidhi kartaa ugu yaraan hal qalab oo qanjaruufo ah.
• Qaybta router-ka ee qalabku waxa laga yaabaa inaanay aad u wanaagsanayn, degganayn, ama aanay taageerin hawlaha horumarsan sida kaydinta shabakadaha ama VPN^(VPNs) -yada .

Arrin kale oo weyn oo ku saabsan adeegsiga aaladaha isku dhafan waa inay la xiriirtaa raadadka Wi-Fi . Maalmahan isticmaalayaasha badankood waxay rabaan Wi-Fi inay daboosho gurigooda oo dhan, iyo inaad ku nooshahay guri yar mooyaane, hal router malaha ma gooyn doono, taas oo ah hal sabab oo aad u rabto inaad haysato modem iyo router gaar ah.

Ka Kiraynta Aaladda-Dhammaan-Kaliya ee ISP-gaaga

ISP^(ISPs) -yo badan ayaa bixiya qalab loo dhan yahay oo ka kooban router iyo modem nooca xiriirkaaga gaarka ah. Haddii aadan awoodin inaad iibsato xalkaaga oo ayan ka dhigan kharash dheeraad ah oo dheeraad ah oo aad kiraysanayso bishii, wax dhib ah kuma laha isticmaalka qalabkan in muddo ah. 

Si kastaba ha ahaatee, ISP^(ISPs) -yadu waxay u janjeeraan inay ku xidhxidhaan aaladaha ugu jaban ee ay ku xidhi karaan adeegyadooda. Haddii ay tahay router-ka-off-the-shelf, waxaad ka akhrisan kartaa dib u eegista ku saabsan, laakiin mararka qaarkood qalabkan waa la beddelaa oo dib baa loo beddelaa, taas oo adkeyneysa in la ogaado inay wax fiican yihiin.

Sidoo kale, la soco in ISP^(ISPs) -yada qaarkood ay kuu ogolaanayaan inaad sii haysato router-ka mar haddii lacag laga bixiyo, halka kuwa kalena ay bixiyaan kiro saafi ah, taas oo macnaheedu yahay inaad dib u soo celiso qalabka markaad dhammayso is-diiwaangelintaada. Guud ahaan, way fiican tahay in la doorto ikhtiyaarka kirada-la-la-hawlgalayaasha haddii la heli karo.

Isticmaalka Modem oo leh Router gooni ah

Haddii aad hore u heshay modem oo aad weli u baahan tahay router ama aad u baahan tahay inaad soo iibsato labada shay, waxaa jira faa'iidooyin kala duwan oo lagu kala saaro labada.

Hal shay, waxaad diirada saari kartaa miisaaniyadaada xalkaaga router oo si fudud u iibso modem aasaasiga ah. Ilaa inta modemku ku socdo xawaaraha xidhiidhkaagu bixiyo, runtii wax badan oo laga raadinayo qalabkan ma jiraan.

Haddii aad leedahay guri weyn oo aad rabto inaad ku faafiso Wi-Fi-ga^(Wi-Fi) agagaarka, waxaad isticmaali kartaa isku-xidhka Wi-Fi-ga^(Wi-Fi) . Kuwani waa xalka la doorbido, laakiin waxaad isticmaali kartaa ethernet powerline iyo sidoo kale fidinta Wi-Fi . Haddii aad isticmaasho hal router, waxaad haysataa ikhtiyaarka ah inaad isticmaasho Wi-Fi-ku-^(Wi-Fi) celiyeyaasha, laakiin kuwani waxay la yimaadaan ganaaxyo xawli ah oo daran, mana ku talin karno maalmahan.

Waxa kale oo aad haysataa ikhtiyaarka ah in aad ku xidho dhibco galmo oo dheeraad ah (ama router duug ah oo loo dejiyay qaabka loo galo) si loo kordhiyo gaadhista shabakadaada iyada oo aan wax xawli ah la kulmin. Tani waa ikhtiyaar wanaagsan haddii aad rabto inaad lacag kaydsato marka la barbar dhigo xalka router mesh ama aad horeba u haysatay dhowr router duug ah oo ku jira armaajooyinka.

Soo koobid

Aan ku soo koobno ​​qodobbada ugu muhiimsan:

• Marka si adag loo hadlo, waxaad u baahan tahay oo kaliya modem si aad ugu xidho internetka.
• Modem-yada^(Modems) guud ahaan waxay bixiyaan hal deked oo Ethernet ah mana laha Wi-Fi .
• Waxaad u baahan tahay router si aad ugu xidho dhammaan qalabka gurigaaga modem-ka.
• Waxaad iibsan kartaa qalabka modem iyo router combo, laakiin waxay leeyihiin tanaasul.
• Mashruucyada shabakadaha mesh^{(Mesh network routers)} ama fidiyeyaasha laynka^{(powerline extenders)} ayaa ka sarreeya Wi-Fi-ku-celiyeyaasha waxaana si toos ah loogu xidhi karaa dekedda Ethernet modem-ka . Ka dhigista tan ka doorasha wanaagsan marka loo eego isku dhafka modem-router unit ee guryaha waaweyn.

Hadda waa inaad si cad u fahamtaa shaqooyinka kala duwan ee modem-ka iyo router-yada ay qabtaan, kuwaas oo ay tahay inaad u hesho baahiyahaaga, iyo siyaabaha kala duwan ee qalabkan loo isku dari karo.

Do You Need a Modem and a Router for Internet with a New ISP?

When you sign up for new internet service, you may be offered a modem and a routеr or one device that does both jobs. Do you really need to get a modem and a router to use the internet? It’s time to clear up a few misconceptions.

Clearing Up the Meaning of “Modem”

The word “modem” is short for modulator/demodulator. It refers to a device used for dial-up internet, where data is sent over the same copper telephone lines that voice calls use.

The modem takes the ones and zeroes that represent the data packets sent over the internet and turns them into sound frequencies over copper wire. It also does the reverse, listening to the sounds coming from the internet and turning them back into binary code.

Modern modems used with DSL, fiber, cable, and mobile data are not modems in the term’s original sense. However, what they do have in common is converting digital data from the computer into the format of the transmission system—for example, converting electrical impulses into the light pulses used in fiber optics.

The most important thing that you should know is that a modem is a device that connects you to the greater internet. It’s the transition point from your home LAN (Local Area Network) to the WAN (Wide Area Network).

What Is a “Router”?

Network data enters and leaves your home or business through the modem. Still, it’s a router that organizes the network traffic to each individual device, both between each other on the internal network and between those devices and the internet.

A router’s job is complicated, and these devices are basically dedicated computers with their own CPU, memory, and operating system. You can hook up network switches, PCs, smartphones, and any other Wi-Fi or Ethernet device to a router, and it will figure out where to send each packet. Routers, at least more expensive ones, can also run network applications. For example, it can act as a VPN device or manage network-attached storage.

Most routers offer at least four Ethernet ports and Wi-Fi, capable of connecting and managing dozens or even hundreds of devices. Unless you literally only have one device you want to connect to the internet through a modem, you’re going to want some type of router.

Fiber Vs. DSL Vs. Cable Vs. Cellular Modems

Although many devices share the label “modem,” they aren’t interchangeable. Most home broadband modems have an Ethernet port on your side of the connection, but they’re radically different on the internet side of things.  Fiber modems connect to a fiber connection, DSL connects to copper telephone wire, cable modems connect to coaxial TV cables, and cellular modems use microwave radio signals.

So, in this context, the answer to “do I need a modem?” is “yes” if you’re moving from one type of connection to another. Your old DSL modem isn’t going to work with fiber or cable connections, for example.

Sometimes the Modem Is Already There

If you move into an apartment building or home where there’s a “fiber” connection, what you may find is a plain old Ethernet port, to which you can connect any router with an ethernet “WAN” port. In other words, you don’t need to buy a modem because there’s already one installed.

This is especially true in the case of fiber. People think of “fiber modems” as ethernet routers that connect to ONTs (Optical Network Terminals). That’s the device that converts Ethernet electrical signals to light pulses.

Fiber routers are therefore just regular routers, but they usually have support for faster Ethernet standards. After all, if you have gigabit fiber but connect a router that only supports 100Mbps ethernet, you’d lose 90% of your internet connection’s full speed!

If there’s a device with just one or two Ethernet ports and no Wi-Fi, you’re probably looking at a modem to which you can connect a router to expand its functionality.

The Pros and Cons of All-In-One Devices

If you need a modem for your connection type, since one isn’t included in the ISP plan or wasn’t already installed, you could buy a combo device containing both a modem for your broadband type and an Ethernet and Wi-Fi router.

You only need an all-in-one unit like this if you don’t already have a modem, but if you do need a modem, there are a few advantages (and disadvantages) to going for a single device that does everything.

On the positive side of the equation:

• It’s usually cheaper than two separate devices.
• You only have to deal with one unified setup process.
• Troubleshooting is easier since there are fewer separate devices involved.

On the not-so-positive side of the equation:

• If the device fails, you have no internet. With a separate modem, you could still hook up at least one device in a pinch.
• The router portion of the device may not be very good, stable, or support advanced functions such as network storage or VPNs.

Another major issue with using a combination device has to do with Wi-Fi footprint. These days most users want Wi-Fi to cover their entire home, and unless you live in a small apartment, a single router probably isn’t going to cut it, which is one reason you might want to have a separate modem and router.

Renting an All-In-One Device From Your ISP

Many ISPs offer an all-in-one device that contains both a router and a modem for your specific type of connection. If you can’t afford to buy your own solution and it doesn’t represent a significant extra cost to your monthly rental, there’s no harm in using these devices for a while. 

However, ISPs tend to bundle the cheapest devices they can with their services. If it’s an off-the-shelf router, you can read reviews about it, but sometimes these devices are modified and rebranded, making it hard to know if they’re any good.

Also, be aware that some ISPs let you keep the router once it’s paid off, while others only offer a pure rental, which means you have to give the device back when you end your subscription. In general, it’s better to choose the rent-to-own option if it’s available.

Using a Modem With a Separate Router

Whether you’ve already got a modem and still need a router or you need to purchase both items, there are distinct advantages to separating the two.

For one thing, you can focus your budget on your router solution and simply buy a basic modem. As long as the modem runs at the speed your connection offers, there’s really not much to look for in these devices.

If you have a large home and want to spread the Wi-Fi around, you can use a mesh Wi-Fi router. These are the preferred solution, but you can use powerline ethernet and Wi-Fi extenders as well. If you use a single router, you have the option of using Wi-Fi repeaters, but these come with severe speed and latency penalties, and we can’t recommend them these days.

You also have the option of connecting additional access points (or an old router set to access point mode) to extend your network’s reach without speed compromises. This is a good option if you want to save money compared to a mesh router solution or already have a few old routers in the cupboard.

Summing It Up

Let’s sum it all up down to the most important points:

• Strictly speaking, you only need a modem to connect to the internet.
• Modems generally only offer a single Ethernet port and no Wi-Fi.
• You need a router to connect all the devices in your home to the modem.
• You can buy a modem and router combo device, but they have compromises.
• Mesh network routers or powerline extenders are superior to Wi-Fi repeaters and can be directly connected to a modem’s Ethernet port. Making this a better choice than a combination modem-router unit for large homes.

Now you should have a clear understanding of the different jobs modems and routers do, which you should have for your needs, and the different ways these devices can be combined.
