  • The D-Link DWL-800AP+ as a wireless repeater to extend wireless range – Part 7

    So, according to D-Link there is a short list of access points that the DWL-800AP+ will repeat for. They are all d-link branded access points. It seems that there have been firmware updates to improve the compatibility with more models (of d-link access points.) Some of the incompatibilities have been with WEP encryption from what I’ve read.

  • The D-Link DWL-800AP+ as a wireless repeater to extend wireless range – Part 6

    Ok, so here’s the synopsis… I’ve spent the last few articles setting up a D-link DWL-800AP+ as a repeater for a linksys WAP11 (v. 1.1) As of the end of the last entry I had a bit of a problem with WEP but that seems to have been resolved now and here I am to fill you in on what went wrong. It was really a simple mistake. When I copied and pasted over from the linksys….

  • The D-Link DWL-800AP+ as a wireless repeater to extend wireless range – Part 5

    So, I set a WEP key on the linksys (WAP11 v. 1.1) and it promptly disappeared… it stopped responding (over the WIRED network) to my wap11gui admin tool. I quickly realized that part of the problem is from having two network cards attached (both in the 192.168.0 range)… disconnect the usb card and reconnect. Then I use the “security” tab to enable WEP (128-bit)

  • The D-Link DWL-800AP+ as a wireless repeater to extend wireless range – Part 4

    Ok, so now I had to add the new D-Link’s MAC address to the list of authorized MAC’s in the Linksys WAP11 (v. 1.1) For this, I call on wap11gui. Used to (since I use linux), I would have to suffer through a Windows boot on the laptop and balance the laptop on the edge of the bed and connect through usb to the linksys… now I can just administer it from my desk. Nice… Anyway, I log into that and Visit the “security” tab and “Authorized Mac”, and add the d-Link DWL-800AP+ to the list.

  • The D-Link DWL-800AP+ as a wireless repeater to extend wireless range – Part 3

    So, now that I was “in” the DWL-800AP+ it was time to see if I could set it up as a repeater. I visited the “wireless” tab of the web based configuration and chose Repeater mode instead of AP mode and saw that I would need the Mac address of the access point that I wanted to “repeat” signal from. In this case it’s the old Linksys WAP11 v. 1.1 So, I opened up a console and (as root) did an arpping 192.168.0.250 (the ip address of my Linksys AP). Got the reply back and typed it in.

  • The D-Link DWL-800AP+ as a wireless repeater to extend wireless range – Part 2

    For starters, I hooked the D-link DWL-800AP+ up and connected it through a crossover cable to my usb network card. That way I could access it exclusively on one adapter and look online for information with the other adapter, which came in quite handy. The first thing I found was that by default the dwl-800ap+ was configured to use 192.168.0.30 as it’s IP address. This one was not configured with the default settings. (Used / via ebay….) So, I did an nmap -sT 192.168.0.* -e eth1 which scanned the whole 192.168.0. list of addresses using my eth1 adapter (as opposed to the default adapter eth0)

  • The D-Link DWL-800AP+ as a wireless repeater to extend wireless range – Part 1

    I’ve got a single access point for my wireless network layer at the house and unfortunately have at least one real “dead spot” in the house. As luck would have it that dead spot is at the couch… so for some time I’ve looked at ways to extend the wireless network range or other ways. One such possibility of course, is a repeater. These days, most wireless repeaters I see either only work with their brand access point. (So a linksys repeater would only work with certain models of linksys access point…) Or… the repeater would only repeat 802.11g *(the newer wireless) traffic. Given that everything I’ve got is still 802.11b I didn’t really want to do a new round of hardware for ALL the wireless devices (the access point still works….) So… looking for a repeater I went.

  • Search Engines Submission

    This is what hopefully will be the begining of a series of threads on webhosting, web marketing, etc. The first topic up is search engines submission. (This may take several articles…) It’s important to get your web site up and mostly fleshed out before submitting to search engines. Why? Although many may take some time before they spider your site, it is best to make sure that there is a fair amount of content available for them to spider. Some may actually spider fairly quickly, within minutes initially.

  • More testing on the second WMF exploit

    After my Windows 98 tests which failed to exploit the system with either the first or the second vulnerability, I started wondering how well the antivirus companies were doing in detecting this second exploit variation. I had setup and updated metasploit so I could test my Windows 98 SE install against the latest version of the exploit and with each connection to the locally hosted page I got a new random file. After I collected five of these I ran them through virustotal.com to see how well detection has come in just 24 hours.

  • Version 2 of the WMF exploit vs Windows 98 SE

    Ok, I wasn’t quite satisfied with the results of the tests against the first version of the WMF (Windows Metafile) zero day exploit that’s now up to 4 or 5 days or so… Windows 98 is listed as being vulnerable, but there are no patches or workarounds currently available for Windows 98 users. I was mostly curious to see if current exploits could wreck a Windows 98 system. The answer at this point is not that I can see.
