    Important information


    The T61 was replaced by the P50. During attempts to flash Middleton's BIOS (to support SSD SATAII) +fan and memory--I have disabled the Security Chip in the BIOS and left it so. I just tried enabling the chip with very interesting results that make less sense than before.

    I will attach backup to the following:

    IP config on the T61 is: IPv4 Address. . . . . . . . . . . : 192.168.0.10

    IP Scan still shows 5 IP addresses but now one of them, .10, has a dropdown that indicates HTTP

    What is REALLY weird is that the router attached devices now only shows 1 T61 but it's not .10, it's .6!?

    Yes, you answered everything :)

    EDIT: It just dawned on me. Ipconfig or ipconfig /all issued from the T61 ONLY has 1 address and that's .10. So how can the router be showing 5 addresses?
    The issue with the T61 according to the last ipconfig.txt you posted ... the 0 it should be a 1

    The nbscan shows there is no Master browser so that will be part of the problem if one of is getting the wrong IP range from DHCP you must have two DHCP servers running I assume it's the extender it means any PC could get the wrong IP. Is NetBIOS running on all PC as that's needed for Master browser

    Samuria, I have no clue how to do as you ask?

    Eagle51, it doesn't appear to have had the intended result per attached ipconfig. FWIW, the Attached Devices are now back to 5 addresses, although some of the numbers are different.

    If it makes any difference the router has Dynamic QoS turned off for attached devices.

    Hey Mark,
    You should be able to verify what DHCP IPs the Extender is handing out or set to... thru the router admin.
    Is your ISP Modem a modem/router ?
    If so, has it been put in Bridge Mode ?


    Edit: Guess I should have asked if you actually using the Extender for any connections ?

    The T61 is my old laptop that I rejuvenated last week after buying the P50. It was still plugged into the modem and not the router, duh, dunce cap...

    You guys get a medal for tenacity! If you hadn't mentioned the bridge I doubt we would ever have figured out why the T61 disappeared.

    I'm now going to the gym and beat up on the bike for an hour!

    The T61 and P50 see all machines and open them up. My wife is working so I can't check the Dell and desktop from their end but will do so later today.

    There still may be an access/rights problem with one of the machines to another but I'm pooped!

    Thank you all so much again.

    If there is a rights problem It'll be on a new thread. I think I've exhausted your servers on this one.

    As many devices as you have that's easy to overlook ... Glad you got it straighten out :)

    BTW ... Probably be a good idea to set Static IP's for the 4 PCs (maybe a couple other devices), but that's for another day.

    The extender should normally have DHCP turned off so all PC's get the IP from one source. People all go wrong with sharing permission as well as the share you need to set NTFS permissions. Run the scanner again one PC should show as Master browser

    I'll do the best I can to respond given my overall lack of network knowledge.

    Technically, the DST stands for dead spot terminator. I remember being told by the installing technician that the device is not the same as an extender. I use the term extender since, in a practical sense, that's what this thing does. Connecting to either the downstairs router or the upstairs DST is not automatic. Whatever device you're using you have to manually change from router or DST. Typically all our devices get their signal from the router unless we're in the kitchen or living room for a period of time then, if not getting a decent signal, we'd switch to DST for just that time.

    I cannot find a screen that had DHCP enable/disable. The closest I can get is, 'by default, the DST gets its IP address dynamically from the router'.

    Now, with all 4 machines in view and running NetBScan from the same P50, Connie-THINK has a YES for master browser.

    When you look for a pc on the localnetworkwindows doesnt search it asks the master browser for a list as you didnt have one that was part of the problem idealy leave that on for a while with all other pcs on so it can update its list
