Microsoft Vista Home Networking Setup and Options
The most daunting part of upgrading to Windows Vista may be trying to figure out where in the layers of menus the networking and file-sharing options are hidden.
Tips for Securing Your Home Router
Seemingly minor and easily overlooked settings can still have profound security implications. Here are some steps you can take to make sure your wired or wireless home router — and by extension, your network — is as secure as possible.

Buffalo AirStation Local Router Model WLAR-L11L

What's
missing?
The ALRM doesn't support VPN passthru or server hosting for either
PPTP or IPsec protocols.
Although it does support traffic logging, and even displays blocked Internet
access from Packet filtered LAN clients, there's no way to save the
logs or have them sent to either syslog or SNMP clients. The
logs also don't show port scan or other hacking attempts from the WAN
side of the router. The router's default configuration, however,
looks to be pretty secure, with no open TCP ports found on my scan for
common ports.
Finally, the ALRM doesn't support content filtering, let you access
the configuration screens from the WAN side, or let you reboot
the router via the admin interface.
Wireless
throughput
I used netIQ's free
QCheck utilityto see how fast the wireless side of the ALRM would go.
Tests were done using a Buffalo Tech AirStation WLI-PCM-L11 PC card as
the wireless client, and a Windows PC as the other LAN client. Both
clients are on the LAN side of the router, so these tests do not include the
router. Here are the results:
(Tests run with:
- WEP encryption DISABLED
- Tx Rate: Automatic
- Power Save disabled)
[Ver 1.01 firmware]
I started out using a Farallon Skyline 11Mb PC card for
the testing because it's what I had loaded in my laptop. The results
were noticeably worse than my AirStation Standard testing, so I switched
to the Buffalo Tech card and retested. Here are the throughput results
with the Farallon card:

1.0
Possible reasons for the difference? Could be antenna design, drivers,
or that the Skyline uses the Intersil PRISM II chipset and the
Buffalo Tech card (and ALRM) use the Lucent chipset.

I also used Qcheck to test the router's speed

These results are in line with the newer generation router speeds and
fast enough for most broadband connections.
Summary
What a difference a few months makes! Back in September 2000, the
AirStation was a breakthrough product: a professional level 802.11b Access
Point for under $300! Now, in early 2001, client PC card prices
are down from $200 to around $130 and look to be headed below the magic
$100 price point soon. New 802.11b Access Points and routers are
appearing regularly, with many products to choose from.
Given this fast-changing competitive environment, my bottom line is that
the AirStation Local Router stacks up pretty well on price and features,
but falls down on ease of use and ability to be used with DSL.
Buffalo Tech says they're working on the documentation and user interface
to attack the ease of use issue, and will soon have PPPoE and PPTP support.
But with the 802.11b wireless marketplace moving as quickly as it is,
they need to get these weaknesses fixed ASAP, and keep rolling out new
products if they're going to be a major contender.
