    A question on wireless home networking

    Back home in the Philippines we are using an "unlimited" plan wireless broadband called SmartBro. basically the speed as advertised is "up to" 384kbps. so far the speed (the last time i used it) was near that mark but the stability of the broadband was dependent on the signal coming from the cellsite of the network and how far you are. we are using the broadband on the 1st floor of our house and that is also where the laptop is located.

    my questions now is i want to buy a wireless router (like the one one i use here in the UK via TalkTalk) so we can bring the laptop downstairs. basing on the circumstances above would you advice me buying a wireless router? if yes would a high-end "G" router suffice or an an entry level "N" be much practical as i would think it can "compensate" for the low bb signal? and what router can you recommend? * i'm using Netgear's DG834G v.3 at the monement with TT.

    G if your close, N if your not so close

    nothing will help the incoming signal tbh, N will allow a better signal through a couple of walls.

    Re: A question on wireless home networking

    I take it this is to share the broadband across multiple laptops or devices?

    What kind of equipment do you have to recieve the broadband? is it a little USB stick?

    To share the broadband over a G or N network, you will need a router that can accept the USB stick (few are very far between), or set up one PC/laptop to share the broadband over the wifi network, meaning that laptop will need to be on all the time.

    Re: A question on wireless home networking

    the way i understand it is that it is a wireless broadband with an antenna/receiver installed on top of our roof that is pointed towards the nearest cellsite that in my knowledge is 3G even if it is advertised as "up to" 383kbps. they say it's an "always on" connection (like here in the UK) and we only have one laptop we are using and it is connected to the receiver/entenna thingy via a simple black cable similar to the one used in outdoor aerials.. i only want a suitable router so i can use the laptop wirelessly and bring it anywhere inside the house. that is what i know and what i want.

    Re: A question on wireless home networking

    How does this boradband get from the roof top reciever to your current laptop?

    I had assumed it was like the little adapters you get for all the mobile networks here for their Mobile Broadband service. But obviously not.

    Re: A question on wireless home networking

    the system works similarly like this:

    there is an outdoor antenna that is pointed towards the nearest cellsite and an indoor receiver of some sort connected via a cable then another cable that is then connected to the ethernet port of our laptop. that is setup of our broadband at home.


    further advice please...

    Re: A question on wireless home networking

    If I'm understanding you correctly, you have some type of wireless receiver downstairs, connected to a roof aerial, and to your laptop, with that latter link being via an ethernet cable to the ethernet port on your laptop.

    If so, and if you want to free the laptop from that cable link, then you need a wireless router and either a wifi capability in your laptop, or a plug-in wifi card for the laptop, probably either a PCCard or USB dongle.

    Any router you get is likely to several "LAN" ports, and one WAN port. The WAN (Wide Area Network) port connects you LAN to some sort of upstream network. In your case here, it's TalkTalk, but it could equally well be an ADSL modem onto Sky, or a cable modem onto NTL, or whatever.

    If that's the case, then all you'll need to do is buy a router, and instead of plugging your 3G receiver into the laptop, you plug it into the router's WAN port.

    Then, you can connect your laptop either to one of the LAN ports on the router via an ethernet cable (though that doesn't achieve much over what you already have), or you connect to the router via the WiFi link.

    And in that case, it pretty much comes back to what Gonzo said in the second post ..... G if you're close, and N if you're further away.

    I use G, and have no trouble up to two floors away and through a couple of walls. But it's not quite as simple as that. Wifi uses a relatively high frequency signal, and the higher the frequency of signal, generally the more susceptible to obstruction it is. Walls will reduce signal strength, but other things (like heavy meal equipment such as a big freezer) will reduce it a LOT more. Ironically, G tends to be more susceptible to water as an obstruction than N, so a water tank can be an issue too. N uses a 5GHz signal (and 2.4GHz), and that 5GHz signal finds it harder to penetrate obstructions like walls, but it also scatters on obstacles, so you tend to get more reflected/rebounded signals.

    I have been known to do site surveys for wifi installations, and you have to look quite carefully at the physical environment if you're going to get the best results, because precisely where you place routers (or bridges, repeaters, etc) can have a critical effect on the resilience and throughput of the network.

    You might find, for instance, that putting a router in one spot (say, in your lounge) will give you no signal at all in your bedroom, but moving it a few feet (so that that freezer isn't in-between) resolves the problem.

    If your home situation is such that everything is going to be within, say, 50 feet of the router and only one wall between you and the router with no other heavy obstacles, then G would probably be fine. The further away you get, and/or the more walls, floors and obstacles you get, the more benefit you'll get from N.

    But bear in mind, despite N's benefits (and potentially greater bit rate), the standard is not approved, so you'll need to be careful that whatever you buy for the laptop works well with whatever you buy as a router. Sticking with a single brand is therefore probably a good idea. And, as and when the standard does get ratified, it may not be in a way that works with the hardware currently on sale. At that point, you'll perhaps find it hard to get additional hardware that works. So, either be prepared to replace it all, or make sure that whatever you buy can be FULLY upgraded by flashing the BIOS or by a manufacturer BIOS replacement.

    Re: A question on wireless home networking

    my laptop is a Lenovo (bought 2008) and has built-in wi-fi on it. like i said on my last reply it is connected to this receive thing thru the laptop's ethernet cable.

    if i will be bringing the laptop downstairs in theory there would be only 1 wall that separates the living room upstairs (where the laptop is located) and the living room downstairs where i would want the laptop will be. and this wall is the one leading from the stairs.

    so, would a wireless router be the one i'm looking for? and will this router be the one to take the place of that receiver thing? and if yes, what exact make & model of router can you recommend?

    The router takes the place of the laptop at the end of the etehrnet cable coming from the 3G reciever.

    The only one I have actual experience with is the Edimax 802.11n Router that Scan have (can't remember the model number). But any boradband/cable router will do the job. Do not use an ADSL router or any other one with a modem integrated.
