Wireless without modem or with modem?

Agera One · Dec 4, 2014

I'm using cable broadband internet (by which i'm accessing Tom's Hardware now). There is one ethernet (RJ 45) coming from over my house to get internet access. The ISP made some changes to my laptop and made a connection, so that this cable without any router can be used only in this laptop. I decided to buy a DSL router (by what means I found it as DSL router is by speedtest.net - both up and down are same). Now coming to the wireless router selection, I came across two kinds - Wireless with modem & without modem. Which one should I buy?

The one with modem is typically used for ADSL connections which uses RJ11 phone type plug. So generally any router with RJ45 WAN plug should do.

That's not what cable broadband means. Cable broadband is usually used to refer to broadband over a Cable TV (Hybrid fibre-coax) network. You've got internet via ethernet - probably not technically broadband.

I decided to buy a DSL router (by what means I found it as DSL router is by speedtest.net - both up and down are same).

Again, nope. DSL is broadband via a phone line. Most common type is ADSL, followed by VDSL. Both are heavily asymmetric. If your internet connection plugs directly into your laptop, it's almost certainly not DSL.

A DSL router is a way to refer to a combination of a DSL modem, a router, and sometimes (if the word 'Wireless' is in there) a Wireless Access Point.

You want a router with just a WAP builtin, no modem. If it says DSL or ADSL, avoid.

Tested just now:

At the time of using this connection in the 1st month, I contacted them and they said "you need a DSL router to share it to multiple devices". Also, I read it somewhere in google that DSL has symmetric up & down speeds - ADSL has high down speed and low up speed. So, I though I'm having a DSL connection. Is this not the way to find what type of connection I have?

DSL = Digital Subscriber Line, a set of standards for broadband over phone lines. You may be thinking of SHDSL, but you can get 1/1 over standard ADSL, it just means that you're being limited below what the line could provide.

Regardless, if you plug your broadband line into your laptop directly, it's not any form of DSL. I'm guessing they meant WiFi router.

I have fairly asymmetric speeds, but don't have DSL:

But I have a ADSL2+ router from my friend (he switched to a newer one). So I cannot connect to this one. I contacted ISP for "how to connect to router?", but after asking me to read what type of router I'm having in the label, I read ADSL2+ and suddenly they said, "Sir, you need DSL router to share the connection". I'm confused now.

Someone Somewhere · Dec 4, 2014

I think they're lost.

Do you know what the model number of the router is?

Does your internet connection currently go through a modem or router, or just straight to your laptop's ethernet jack from the wall?

Ra_V_en · Dec 4, 2014

Obviously they made a mistake saying so, ADSL, DSL or whatever they call it has RJ11 WAN plug while you need RJ45 one. Its obvious it wont work since the signal is not the same even you somehow manage to plug that tougher.

You can use something like this:

but not this:

Simple as that.

Tested again:

Okay, this is the router image (Indian govt. ISP made, local one but in good condition):

I can't get the image of the label under the router. But I'll text it here. (smartphone camera is dumb, lol)

ADSL2+CPE/IAD
MODEL: AN-1020-21 (and then there is Huge font saying) TYPE-II
Input: 12V/0.75A

Ultimately it's MANUAL: http://www.vmcsystems.in/images/product_image/brochure/1310963798ADSL2ModemRouterProductBrief.pdf

LAN 1 to LAN 4 ports are off RJ 45.
VOIP & DSL ports are off RJ 11.

There's no such thing as "WAN". But it was used with the phone line connection which had 512 Kbps down and very lower up speed.

This made me think, asymmetric speeds = ADSL & symmetric speeds = DSL :/

Someone Somewhere · Dec 4, 2014

OK, yes, that is a DSL router. I thought you said you had an RJ45 cable entering the house?

How is your laptop connected to the router? I think reconfiguring the current router should be enough to allow you to use other devices.

Symmetric DSL is typically only found in business applications. You've just got an ADSL connection with a heavily limited downstream.

Ra_V_en · Dec 4, 2014

False answers based on false informations :S

@UP you meant upstream ofc

and indeed its now even more uknown about this network scheme. Now im just guessing the laptop is working over wifi but who knows, maybe this router just sits there and do nothing.

Someone Somewhere · Dec 4, 2014

It's downstream that's been artificially limited; ADSL usually tops out at ~1Mb/s unless it's Annex M, in which case you might get a little more.

Someone Somewhere :

Sorry, you mean what they're saying is about a DSL router? or what I've posted is a DSL router?

I don't know even there is a router here (I'm so dumb now), but a long cable comes into the home from outside (along with so much cables, longer in length wounded in circles and tied to steel rods,

) But the cable I'm using to connect to the laptop is a RJ-45.

please provide us with further information, like:

which tariff:

is there another device between laptop and wall plug?

Someone Somewhere · Dec 4, 2014

What you've posted is a DSL router.

Can you post a diagram of how everything's wired up?

Ra_V_en · Dec 4, 2014

Well idk about any artificial limitations rather than standard limitation in coop with line quality.. and I'm confident its about upstream without even checking on wiki:
http://en.wikipedia.org/wiki/Asymmetric_digital_subscriber_line
From ISP point of view it maybe is a downstream, so even you are wrong you might be right

helpstar · Dec 4, 2014

The best thing I read:
"This service is offered for residential customers only and will not be connected to a wireless router nor is it allowed for Internet sharing. Connection offered only for desktops."

Agera One · Dec 4, 2014

helpstar :

But they said "you need to buy a DSL (loud and clear) router to share it to maximum of 4 devices without losing speed" I used this connection to multiple devices by mhotspot software in the laptop.

Someone Somewhere :

DSL? It's manual says its ADSL and there are no specs about DSLs in the manual?

Someone Somewhere · Dec 4, 2014

Ra_V_en :

Round numbers like that are typically a coded/profile-based limit on the sync rate, plus you would expect to see a corresponding decrease in upstream if it was due to interference or attenuation. Artificial, even if it's at layer one. Running at maximum line speed would result in a far more asymmetric result.

Upstream is normally 1Mb/s or less on ADSL, so isn't limited. They're limiting downstream, i.e. down from the internet towards the customer.

helpstar :

Hah. OK, not 100% sure if we're meant to help you get around it, but... I dislike clauses like that...

Is there an ethernet cable from the router to your laptop, or what?

Agera One · Dec 4, 2014

Yes, only one RJ-45 ethernet jack to get to the internet. No other cables.

I'll tell you something. Once I tried connecting this "RJ-45" into LAN 1 (I know its dumb) of the above posted router and turned the wireless ON. Laptop showed full Wi-Fi signal with warning triangle. But never can be accessed.

helpstar · Dec 4, 2014

please let the terms dsl and adsl aside. Nothing to do with your thing. You got a 1Mbps Internet.

Normally it´s connected like:
ISP -> Cable TV connection in your house -> cable modem with only one RJ45 plug -> laptop

the first thing to know, is it possible to deactivate the integrated modem inside your AN-1020-21 TYPE-II

is there another device between laptop and wall plug?

you have to do this first or no Internet connection will be provided.
