Upgrading Broadband Router

    Apologies if this subject has been covered previously

    I am considering upgrading/replacing my wi-fi broadband router/modem (a
    Netgear DGN1000SP as a supplied by my ISP some years ago) with something
    similar to the BT Home hub or better for stronger wi-fi coverage within
    the house and possibly better overall wi-fi experience. The Netgear
    seems to suffer a lot from 'resolving host' delays at peak times, which
    often clear if i reset the router/modem but that gets to be a PITA.

    Can anyone recommend a reasonably priced wi-fi router that might give
    greater wi-fi coverage and performance.

    TIA Ash

    Do you get the same "resolving host" problems when your computer is
    connected to the router by wire, with the WiFi disabled?

    If so, the router is not your problem, it is probably your ISP.

    I can't recommend a reasonably priced wi-fi router, but a Vigor 2830
    might perform better if you can justify the price.

    To repeat the gist of one of my earlier postings:

    WiFi performance is usually more dependent on the number and nature of
    walls through which the signal must pass, than the make & model of AP.

    Further, the maximum output power is limited by design, in order to meet
    the "license free" operating conditions. So, in principle no one AP
    will work any better than any other. Of course in practise some do work
    better, perhaps because they have the maximum legal power, or have
    receivers which are more sensitive, or use multiple antennae to work
    around obstructions.

    If you want to guarantee coverage throughout a building you should plan
    for an AP in each room connected by Ethernet cable to the LAN. Something
    less than that might work, but cannot be guaranteed. Placing the AP in
    the optimum location should help - but then you might require an
    Ethernet cable from the AP to your router.

  3. I've mentioned it before, but this is what I've got-


    I don't know how much like the BT Home Hub you would like it to be,
    but this one also contains two modems, ADSL and VDSL, so an upgrade to
    fibre only requires you to make a software change and you don't have
    to accept the default two box arrangement with a modem supplied by
    Openreach and a separate router. It hasn't given me any problems and
    it runs very cool to the touch, which must be a good thing.

    Sounds more like an overloaded DNS lookup problem to me.

    What happens if you note down a couple of numeric quad nnn.mmm.ooo.ppp
    addresses of "slow" sites and directly enter them into your browser?
    Or their DNS server.
    They have got noticeably better. My Victorian walls have chicken wire
    embedded in them to prevent the plaster slumping. They make a pretty
    good Faraday cage. Most recent router reaches all most rooms. High gain
    directional antenna and a dongle has a range of 200m in free air.
    (cantenna if you are into DIY and pringles)
    Mostly it is the phased multiple antennae allowing some beamshaping.
    Provided you don't have religious objections to ethernet over mains you
    can get decent performance with that to reach other fixed kit.

    Doesn't match my experience: only a very modest variation in range with
    various routers from a Netgear DG834G through to a Linksys EA6300 (using
    802.11n 2.4GHz). Speed at a given range is better, but I think due to
    "g" vs "n".
    Even if you drop the transmit power to keep the EIRP under the
    license-free limit, which is strangely rarely mentioned? ;)

    Such as a second access point, or a router acting as one, like Michael
    suggested since your post; there are combined units available but they
    may be less desirable due to restricting possible aerial locations. (But
    combined is neater, of course.)

    As for performance, in circumstances that are far from ideal but perhaps
    not unusual if you're having WiFi range issues - a separate ring,
    perhaps 30m of cable - with a pair of cheap 85Mbit/s units, I get only
    10-15Mbit/s throughput in one direction (I presume local interference).
    Not great for local connectivity but absolutely fine for Internet stuff
    with the probable exception of "UltraHD" video though.

  7. Draytek 2860, although that is business class and expensive.

  8. There are a number of options v , n etc. depending on whether you want Wi-Fi and / or phone sockets (for VOIP). These increases the price a little.

    AAMOI I have just changed my IP to BT ADSL (not Fibre, sad i know but
    their BT Sport package is very good at no extra cost).

    Since moving over the wi-fi speed has improved to 21Mbps from 15Mbps
    previously and the wi-fi coverage (with the Home Hub 4) around the house
    has improved noticeably too.

    It would appear i have benefitted from the swap which was what i was
    looking for in the OP

    You have benefited from the 'dual band' capabilities supplied by the
    later Home Hubs not by any stronger signals as these are limited by
    legist ration.

    This one is getting a bit silly.

    Wi-fi transmitter power is indeed limited by legislation but most
    routers run at rather lower power than that. The majority are capable
    of 250mW but don't do more than 100mW (or less) in standard config.
    Not a lot of good though if the other end of the link - a phone or
    tablet - can only do 10-20mW! In the comms business it is known as

    In terms of frequency bands, whilst the 5GHz band will not travel so
    far and has less radio channels, there are also drmatically less
    users, so clashing with someone else is much less likely. In terms of
    the 2.4GHz band there are 13 channels of which 11, 1, 6, and 13 are
    the most common defaults - and the vast majority of users don't have
    clue what it is about or how to change the radio channel. Shift your
    router to one of chans 3/4/8/9 and you will probably have little
    problem. If you have an Android smartphone download the free all Wi-fi
    analyser and it will show you graphically who is using which channel
    around you.

    13 is legal in the UK, but it's surprising the amount of kit that's
    reluctant to use it because it's not legal everywhere else.
    partially overlap with the users of channels 1/6/11 anyway.

    Thanks, i did already know the wi-fi transmitter power was limited by
    legislation but that wasn't what i was trying to understand which was
    how did the router 'dual band' capability improve my broadband
    experience which it appears to have done and your explanation seems to
    answer that at least in part regarding the 'range' if not the improved
    speed. Cheers

    Dual band routers usually handle the same network on both frequencies.
    However whilst the router is capable of two bands simultaneously your
    mobile/laptop or whatever is not. By default most will go to 2.4GHz
    and you will have to manually force it to 5GHz. Having said that once
    there it should stay there for your network.

    There is also another advantage of some routers - you can run them as
    two seperate wireless networks using the same Interweb feed. For
    instance in a small hotel or caravan site the 5GHz could be set up as
    a private encrypted net that is invisible to other users but which
    your equipment knows about and will prefer. The 2.4GHz net can be set
    as open with a different ID for your visitors to use. Encryption is
    simple and prefered and can have a different encryption code to that
    used on the 5GHz side.

    In other words the router uses one outside world connection but
    effectively runs two independent wireless networks.

    As a final point, there is a lot of other users around 2.4GHz - the
    new 4G ar 2.6, 3G at 2.1 and microwave ovens around 2.5 all of which
    can cause interference to relatively cheap receivers. 5GHz on the
    other hand is fairly interference free so even though the signal at
    any given point may be much weaker on 5GHz than on 2.4GHz the 5GHz
    signal will often be much more reliable.
