Then I saw there were no lights on my wireless access point.  This was not good news.<\/p>\n<p>I couldn&#8217;t fix it quickly and running a cable was not an option either as it would have meant leaving the house unsecured all weekend.  So, I just had to accept that I had no DNS, no DHCP, and that the mail server would be offline for the weekend.<\/p>\n<p>When I got home last night, I set up a temporary (wired) connection and thought about how to fix the Wi-Fi &#8211; it seemed I had a few options:<\/p>\n<ul>\n<li>Buy a new DC power adapter for my D-Link DWL-2000AP+ &#8211; inexpensive but the D-Link was a cheap access point &#8211; a new DC adapter could cost almost as much as the unit is worth and if the power adapter has blown up, the main unit could be next.<\/li>\n<li>Buy a new access point (and optionally move up to 802.11pre-n) &#8211; a new access point could be good, but pre-n equipment is still quite expensive &#8211; and I&#8217;ve never been that happy with pre-anything standards, even back in the days of 56Kbps modems.  Add to that the fact that I have a mixture of 802.11g and 802.11n equipment (mostly built in to computers) &#8211; and the &#8220;g&#8221; kit would slow an &#8220;n&#8221; network down to 54Mbps.<\/li>\n<li>Replace my individual router and access point with a combined wireless-modem-router (like the Netgear DG834G that one of my friends lent me &#8211; a left-over from his disastrous encounter with Virgin Media&#8217;s ADSL &#8220;service&#8221; &#8211; or one of the Draytek devices that I&#8217;ve heard so many good things about) &#8211;  but <a href=\"https:\/\/www.markwilson.co.uk\/blog\/2004\/07\/preventing-denial-of-service-attacks.htm\">my Solwise ADSL router<\/a> is still going strong (aside from the occasional reboot) and I&#8217;d have to reconfigure all my firewall rules.<\/li>\n<li>Dump Wi-Fi in favour of <a href=\"http:\/\/en.wikipedia.org\/wiki\/HomePlug_Powerline_Alliance\">HomePlug AV<\/a> technologies &#8211; potentially faster (at least faster than 802.11g) but also quite expensive, still a relatively immature technology and, based on most of the reviews I&#8217;ve seen, highly dependant upon the quality of the wiring in the house.<\/li>\n<\/ul>\n<p>In the end, I decided to splash out on a new access point &#8211; and this time I got the one that I thought about in 2005 but didn&#8217;t want to spend the money on &#8211; a <a href=\"http:\/\/www.netgear.co.uk\/wireless_accesspoint_wg102.php\">Netgear ProSafe WG102<\/a>.  I got mine from <a href=\"http:\/\/www.broadbandbuyer.co.uk\/\">BroadbandBuyer<\/a> for a touch over \u00c2\u00a380 (the added bonus was that they are only 7 miles away from my house, had them in stock, and I could collect) so by late morning my Wi-Fi was back online and the temporary cables down the stairs were gone and the garage door was closed again.<\/p>\n<p><img data-recalc-dims=\"1\" decoding=\"async\" src=\"https:\/\/i0.wp.com\/www.markwilson.co.uk\/blog\/images\/wg102.jpg?w=700&#038;ssl=1\" alt=\"Netgear ProSafe WG102\" \/>After having set this up, I realised that this is what I should have done first time around &#8211; Netgear&#8217;s ProSafe range is aimed at small businesses but is still reasonably inexpensive &#8211; and so much better than the white plastic consumer rubbish that they churn out (or the D-Link access point that I&#8217;ve been using).  The WG102 is well built, has a really straightforward web interface for management (as well as SNMP support) and supports all the wireless options that I would expect in a modern access point, including various security options and IntelliRF for automatic adjustment of power transmission and channel selection. I&#8217;m using WPA2 (PSK) but the WG102 does include RADIUS support.  It&#8217;s also got a nice big antenna and I&#8217;ve switched off 802.11b to prevent the whole network from being slowed down by one old &#8220;b&#8221; device.  I also use MAC address filtering (easy enough to get around but nevertheless another obstacle in the way of a would-be attacker) but the best features are the ones I haven&#8217;t implemented yet &#8211; like multiple SSIDs and VLANs for granular user access.  If I put a VLAN-capable switch between the access point and my router, I could provide a hotspot for my street but still run my own traffic over it&#8217;s own VLAN.  I guess VLAN-hopping would be a potential attack vector but my Wi-Fi traffic would be encrypted anyway and there&#8217;s another firewall between the wireless network and my data.  If that switch supported <a href=\"http:\/\/en.wikipedia.org\/wiki\/Power_over_Ethernet\">Power over Ethernet<\/a> (PoE) then I could even manage if the WG102 lost it&#8217;s power supply (it has PoE support too).<\/p>\n<p>The WG102 is certainly not the least expensive access point I could have bought but it seems to be money well spent.  It includes a bunch of features that are generally only found devices intended for the enterprise market but comes at a small business price.  I should have bought this years ago.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Two-and-a-half years ago, I upgraded my wireless network in order to move to 802.11g and to implement some half-decent Wi-Fi security but, last Friday, just as I was packing up the car for a weekend away, I noticed that my PC had lost contact with the mail server.
