    Range of wireless router

    It is very dependent on the environment (numbers of walls, trees etc...) You would probably be best trying it out with 1 AP, close to the boundary. See if you can both pick up the signal and go from there. Two WLAN aps won't work together unless they have a bridge mode or similar
  2. Ok, so the problems I described were based on the following: c c c \|/ AP1------Int Service 1 ==================== AP2-----Int Service 2 /|\ c c c Where AP1 and AP2 were both configured with the same SSID, WPA2 key, layer 2 settings etc. On the client side, both APs are configured with the same IP (as a gateway for their clients). Both internet services are discrete, and likely to be provisioned with individual IPs that won't work from the other. As aliali suggests, very messy. Virt, as you suggest, extending the one Layer3 network is best. If AP1 is the Buffalo Hipower unit, and AP2 the Linksys, I would suggest plugging the internet into AP1, and placing AP2 in an area where the most AP1 signal is present, as the magic of radio reciprocity should mean the buffalo receives just as well as the linksys. AP2 would become a basic WDS repeater, with all routing / DHCP / DNS etc, being handled by AP1. You may have to disable the 5Ghz radio on the Linksys, as it might require some smarts on the AP to receive on one and transmit out another. Worth a try regardless.

    Strange firewall log

    Does seem strange. A quick reverse name resolution indicates the two IPs to be home type DSL/cable services: 86400 IN PTR 69-165-240-115.cable.teksavvy.com. 86400 IN PTR 201-66-172-94.paemt701.dsl.brasiltelecom.net.br. and a bit more detail on the second IP from whois: inetnum: 201.66/15 aut-num: AS8167 abuse-c: BTA17 owner: Brasil Telecom S/A - Filial Distrito Federal ownerid: 076.535.764/0326-90 responsible: Brasil Telecom S. A. - CNBRT country: BR
  4. Agree with aliali, the client should "seamlessly" shift from one to the other, however, how are IP addresses being dealt out? Best bet would probably configure both routers with DHCP, using non-overlapping scopes (11-20 on one, 21-30 on the other for example) Only other problem will be TCP/IP connection issues. If you go from one router to the other, your global IP will be different so connections will be lost (assuming the routers are performing a NAT function) has the potential to be troublesome... No real solution, unless you are able to bridge both routers, and can use the 1 IP from both outlets.

    Need another geek!

    What does intermediate / advanced skills mean? We talking CCNA - CCNP type skills here?
  6. I would second jperf (or iperf, its cmd line equivilent) but make sure you understand what the options are, and how best to use them. generally, you can tune the TCP option to get a maximum throughput type figure, and the UDP will generally give a better indication of lag / jitter. Another option might be to setup something like WhatsUpGold (or similar) and pointing it at several PCs. Something like this can run 24/7 and provide an indication on whether there are better or worse times (like lunchtime, when everyone jumps on news.com?). Once again, RTFM to get the best out of it.

    Catalyst switch issue

    You can probably get away with turning CDP off if you wanted to get rid of the message (no cdp enable). However this may break the phone if it is PoE, try it and see what happens on phone reset?

    Multiple WAN IP Addresses

    Do you want it to have multiple WAN interfaces, or just be capable of routing a block of addresses?
  9. Can you paste the ADSL status information? Should be under Advanced -> Status -> ADSL
  10. Try clicking on "Advanced" -> DNS -> +, then type in the dns and hit enter. Then OK, and apply. Working on my mac oh, and check your DHCP server, it should be capable of supplying these values...

    One for the pro's

    I take it you know physically where it resides? If this is the case, trace the LAN cable back to whatever its plugged into. Logon to that device and determine the MAC address (if a Cisco switch -> show mac-address-table interface <blah>) Find out which network/vlan it is on then go to the router and lookup the mac address against the routers arp table (cisco router: show arp | include <mac in aaaa.bbbb.cccc format>) This should give LAN address. All this has the one dependency that the router is talking to something on the network keeping the arp and mac table entries fresh. If it isn't, given you know the network segment, you can ping sweep / nmap to see if it responds, then retry the above. Of course you might have a cdp neighbour on the connected device (as Lew~ suggests), a show cdp neighbour detail will give its LAN and management IP.
  12. channel choice will only make a difference if there are other wireless networks operating on the same channel. If this is the case, choose another (1 or 6) get inSSiDer to see what other wlans are present and the channels they are on. without line of sight you are always going to be screwed, but moving the antennae away from other metal objects should help (as aliali suggested)
  13. your PC probably needs a new IP address. If you were able to talk to it on then you must have had an ip on that same subnet. Try re-addressing it, then giving yourself a static IP on the network and see how you go.
  14. im in exactly the situation (public -> private). Even with the ability to browse whatever I want, my lunchtime browsing habits haven't changed (xkcd.com, couriermail, thedailywtf) Having said that, given the laziness of most of the public sector I understand and agree with the filtering put in place on those networks ;)

    high ping

    Have you tried rebooting the modem/router?
