Sorry guys, Been slammed for a while now. but i see there are several good points here. I will cover them in the order presented.
StoicJ. The default gateway is the same whether wired or wireless. It is the same router and shows being 10.0.50.1 no matter which connection is active.
BGM: yes and no on this one. Until recently, this was left at DHCP on every system, However, I have found that in the past few laptop purchases, some that only had wireless and No wired at all, that unless I specifically configured the "alternate config" for IPV4 (which usd to be an area that I swear was not even there on many systems but i could have been overlooking it) anyway, i found that using autoc/auto for the IP and dns would not work. These new Ultrabooks with No wired at all require that I put in the Office WORK network specifically and ssign an IP and a DNS and i MUST do this in the alternate or the user would have effectively a No connection laptop once they leave the office. I recently noticed Another Option there as well. It says Automatic Private IP as opposed to (I guess) the normal Automatically obtain IP ( Public IP ?) option in the primary window. I would tend to believe that since they only have ONE business network that i am better of putting in a static IP in the alternate configuration
40Hz; The specific i should have just typed it all out are:
255.255.255.0 is subnet
dhcp is set to handle from 10.0.50.100 to 10.0.50.200.
The printers and misc items that have static only are below the 100 so prevent possible conflicts.
10.0.50.75 76 77 78 are all printers
there are a few other misc items that stay down there too.
Above the 200 mark are reserved for special application issues. currently there are none
ALL laptops I have been able to find retail ALWAYS activate Both Wired and WiFi unless you manually turn on Airplane mode or disable to WiFi adapter.
I have always considered this a bad practice just intuitively without an real reason fo it. For one thing , in dhcp , it doubles the IP;s in play since each device gets one for each adapter.
There used to be a product that was FREE once and then disappeared for a while then came back as a "pay-to-play" utility that would switch off the WiFi when you plug in wired. I have even see a few mfrs. say their laptops have this feature. No One has the old Manual WiFi ON/Off switch (and glad it is gone!) The utility old for about $20 but I don't even remember the name. If nothing else it would save battery power if you were wired for network and not connected to a charger.
I am wondering if any of this is related to the continued push toward IPV6 as well?
Either way, Can anyone see a reason to NOT disable WiFi when you have a Better Wired connection? Wired in our office is always 1GB, WiFi may be getting better but not THAT fast. Not even AC band.
This would work like the option to disable the touch pad if using a wired mouse (which IS a good option, everyone likes that one).
If I could find that utility again, I would consider buying it. Don't know why it isn't a built in option anyway
Other than for the fact that Windows now seems to use create several Virtual WiFi adapters for ad-hoc connections to whatever devices you are smart enough to configure them for. Whether or not you even know they are there. Mini Hot spots broadcasting and receiving though i have never checked much to see what they are meant for nor why some laptops seem to have more than one of them.
Thanks for all the info and i am still on the lookout for any info to give this a better solution. If it were an ALL the time thing it would be easier. But it is intermittent and I am leaning toward the possibility that 40Hz brought up about some router not working well on anything but 192.168.x.x.
For the record, 40HZ, maybe I can one-up your #4. We had people who, when the office CABLE IP went down, they would whip out their cellphone and connect their WiFi to IT. But leave their WIRED connection plugged in TOO!
Left me scratching my head as well when i suddenly found half the office able to get internet even though the service was down. Evewn if i unplugged the router.
The solution got a bit clearer when people started complaining they could not print to the network printer. THAT was when i checked their ipconfig/all and saw a WEIRD setup.
Turns out that the Internet connection by one person on the cellphone was provisioning backward through the network switches to offices over 100ft away.
Smart switch did not care if their wire was an IN or an OUT so it happily allowed anyone connected to the same switch that was online before the CABLE went out to stay online feeding though that one cellphone.
I was totally flummoxed! I would not have thought it would work that easily with no provisions for protection or anything, We later found out that this same setup was creating havoc on the network when it was up. In this case . YES there WERE two distinct separate gateways as well as two DNS servers.
In our district (not sure how far this applies) COX has begun using a "Locked DNS" setup. We cannot use ANY other DNS at all. If i change from the primary and secondary THEY provide, we immediately lose Internet connection. Error will be Unable to contact Primary DNS server. I have been told that we are the only place tat has this setup as far as I know. And no one will even explain WHY. Just that we MUST use what they give or.. No Internet at all.
Any ideas on that one?
