PC only network switch!!

It's a conspiracy!
I have a switch that I can plug a PC into and surf with no problem, but when I try to connect my Macbook Pro, no internet at all.
Here is the setup. Dlink DGS-1224T 24 port switch that has one of its ports connected to a wall jack. The wall jack has a small 5 port DLink DSS-5+ Switch II connected to it. The switch has an ethernet cable that goes to the PC which can surf the internet but the same cable hooked to the Mac will not allow me to surf.
If I remove the DLink DSS-5+ and connect the computers straight to the wall jack, both the PC and the Mac can surf. What's the deal with this little 5 port switch working for the PC but not the mac -_- ?
Other stuff:
Both use Static IP's
All cables are from the wall jack are straight through cables (Patch).
I don't know what type of cable connection is between the two switches (crossover or patch).
I used the same functioning cable on the Mac that worked with the PC and still no luck
I tried a 5 port Linksys switch in the place of the 5 port DLink switch and put the line from the wall jack into the Uplink port on the back of the Linksys and then plugged the mac into that switch and still a no go.
I discovered this problem when I was using my Macbook to troubleshoot some network connection issues (turns out that lightning blew out some network fuses of ours) but now I'm wondering just how reliable the Mac is to do future network testing. I was about to label the little switches as bad then along comes PC and he can surf where I cant What's the deal?

Have you double checked, and triple checked your network settings? Setup another location and just leave it at DHCP defaults to see what it reports. Under your current location make sure the IP, GW, and DNS settings are right. Sounds like something is catching in there. Also could be a good idea to wipe out the entire interface and re-add it, could help delete some old cached settings.

Need help setting up WiFi - Xfinity with Network Switch, Time Capsule, Airport Express and Apple TV

Hello - I recently got Comcast Xfinity service. We had switched from a different service. Our wifi service was never great, but prior to Xfinity, it worked decently. But now that we have Xfinity, our wifi is much worse and very unreliable. I am seeking advice on how to setup my various Apple wifi devices in my home. I have attached a diagram that illustrates what I am dealing with. We have a large old house with stone walls. Comcast does not support this issue.
To explain the attached diagram, we have a total of 4 levels in our house - an unfinished basement, 1st floor, 2nd floor, and 3rd floor. The Xfinity router is in the basement and it is connected to a NetGear 10/100 network switch. I already have ethernet cables running from the network switch in the basement to various locations throughout the house. So I have ethernet connected to my time capsule and ethernet connected to each of my 3 Airport express devices. The dark lines running from the network switch to the various devices represents ethernet cable.
The immediate problem that we are having is that we are unable to connect to our wifi networks. The networks show on my mac laptop and my iPhone, for example, but I am unable to connect. I know that I am inputting the correct password, but most of the time, we cannot get in. Sometimes we can..... Very frustrating! Also, due to the fact that I setup what I have over several years, I have multiple network names. I once tried to fix that issue, but was unable to tackle it due to my lack of understanding.
Here is what I am looking to accomplish:
1. Seamless wifi access throughout our house.
2. One name for our wifi network. Right now we have multiple names for multiple networks. Just want to simplify and have only one network. (I guess that an additional "guest network" would be ok, but not absolutely necessary.
Also, if you think I should disable the Xfinity wifi, and just rely on my mac wifi devices, I am perfectly fine with this. Just tell me how to do so.
I have no idea how where to start or how to set this up. I imagine that I would need to disconnect everything and reset and start from scratch? Can someone tell me what I should do? Even general advice would be helpful, but the more specific, the better, given my limited understanding. Any help or advice would be greatly appreciated.
Thanks in advance!

Tacacs authentication fails for one user account for only one switch

Hi,
I am having an scenario, where as Tacacs authentication fails for one user account for only one switch.
The same user account works well for other devices.
The AAA configs are same on every devices in the network.
Heres the show tacacs output from the switch where only one user account fails;
              Socket opens:        157
             Socket closes:        156

What could be the reason ?
No errors on ACS server; same rights had been given to the user account.
Thanks to advise.
Prasey

Hi there,
Does the user get authenticated in the ACS logs?
reports and activity----> failed attempts
ro
reports and activity-----> passed authentications
That will help narrow it down.

Can I use the Time Capsule as a backup drive and wired network switch? I do not want to use the wireless part as I already have an ADSL 2 Wireless Router for that. Thanks.

Hi
I just went from PC to MAC. Have a MAC Mini and wanted to get a time capsule for backups. I would like to use it as a wired device instead of wireless. Would me connecting it to my router do the trick? Can I then use the LAN ports in the back of the capsule like I would a network switch? Can I just disable the wireless router part of the capsule as I already have an ADSL2+ Wireless Router.
Thanks

I wanted to run a cable upstairs from the switch downstairs so the Time capsule becomes my upstairs switch (as I only have Wireless upstairs at the moment. That will work right?
Cheers.
Yes, that is also fine.. ethernet being the cable you run.. !!
You still don't have to use a TC.. which is still a rather expensive box for the job.. an Airport Extreme would offer the same exactly minus hard disk for cheaper price and more than likely better lifespan.. TC with internal power supply run too hot.

Home setup - network switch and 2 Time Capsules

I have an ADSL modem/router (Billion BIPAC 5200G). I have used it previously with wireless turned off. I then used a time capsule in bridge mode so that NAT etc is turned off, and then use it to broadcast wifi and as a backup. It is attached to the modern with ethernet. It worked fine.
I am now in a house with a lot of ethernet ports, linked to a massive hub thing. But it needs a switch to link it all together.
So I am thinking of this setup:
PHONE LINE
to
BILLION ROUTER (Set as a router with wifi turned off)
to
NETWORK SWITCH
to
VARIOUS ethernet enabled devices in different rooms (i.e. printers, Apple TV, TV, Time capsule)
Then I want to use my 2nd time capsule to extend my ground floor network by plugging it in essentially directly into the time capsule via ethernet in roaming mode.
Is this the optimal setup for this? My other idea was to forgo the network switch and do it this way:
PHONE LINE
to
BILLION ROUTER (Set as a router with wifi turned off)
to
VARIOUS ethernet enabled devices INCLUDING the TIME CAPSULE and PRINTER.
then:
To the TIME CAPSULE:
to
VARIOUS ethernet enabled devices INCLUDING Imac, Apple TV and another TIME CAPSULE in roaming mode.
My main questions are: which setup will give me better speeds to all devices. Ie: is the switch even necessary? In my 2nd example, will the first time capsule and printer be available to the Imac.
There seems to be no real advantage to having the TIME CAPSULE in router mode while keeping the BILLION ROUTER as a pass through with NAT off (To avoid Double NAT) except for the guest network capabilities.
If its just simpler to have the network switch, then perhaps that's the way to go. If so: any suggestions on network switches that work well?

It doesn't allow me to select ethernet as an option for internet connection, only dchp, ppoe and one more which isn't ethernet.
DHCP is correct setting. .it will use ethernet but the new AC TC has problems.. it needs a crossover cable with some switches. Or you need to return it and get it replaced as there is something wrong with its wan port.. the new AC model needs a hardware revision and about 3 or 4 firmware upgrades before it hits the status of the Gen4 it replaced.
My questions are: should I connect my time capsules together directly with ethernet using another available port in my new time capsule. I thought my switch would work better. Also, does one time capsule have to be in router mode instead of having both of them in bridge.
Both should be in bridge.. but you can rearrange things to see if any of the other devices works better.
You can use the billion or the old TC.. plug the new TC into those.
Bob is correct though.. the switch is the correct thing for everything to be plugged into .. but in home situation what works is more important than what is best. It if fails in all of them then the WAN port is proven faulty.
Should I be able to use the hdd on the 2nd (older) time machine as essentially a networked hdd for putting movies and music on, and use my new time capsule as the sole backup (occurring both over ethernet for my iMac and wifi for our laptops)
Yes, that is ok.. you just need to get the AC version TC actually working properly.
Give us a few screenshots of things.. that really helps to see.

Hi Tarun 49,
If you are having issues with your iPhone such as you describe, you may want to try some things to troubleshoot.
First, quit all running applications and test again -
iOS: Force an app to close
Next, I would try restarting the iPhone -
Turn your iOS device off and on (restart) and reset
If the issue is still present, you may want to restore the iPhone as a new device -

Thanks for using Apple Support Communities.

QEMU host-only networking using tap devices

I'm trying to setup host-only networking on my QEMU VM running Arch (actually, the Archiso; there is no Arch installation present yet). A short summary:
What I want
connect to the host from the guest system
connect to the guest from the host system
using a tap device (to avoid user-mode networking) on a network bridge (to connect guest and host)
Eventually, I want to run an AMP stack on the VM for web development. (Let's, for now, ignore the fact that I might need an internet connection later on to install packages)
What I tried
I first set up a tap device:
ip tuntap add dev tap0 mode tap
and then a network bridge:
BRIDGE='qemubr0'
brctl addbr ${BRIDGE}
brctl addif ${BRIDGE} tap0
ip link set up dev ${BRIDGE}
The relevant parameters I run QEMU with are:
qemu-system-x86_64 \
-net nic \
-net tap,ifname=tap0,script=no
QEMU starts without any errors, but trying to ping the host from within the VM results in:
-- VM:
# ping 10.0.2.2
connect: Network is unreachable
(FYI: 10.0.2.2 is supposed to be the default IP address of the host system (?) according to http://wiki.qemu.org/Documentation/Networking )

I must admit that my theoretical and practical knowledge on networking is quite limited, so this might be trivial. I'd be happy about any hints in the right direction. Thanks

You are scratching your right ear with the left hand, so to speak.
Let's say on the host, you have a bridge, br0, with an appropriate IP, serving as a gateway (created with your favorite network manager), and you'd like to start a VM whose virtual drive is arch-x86_64, then this is all you need to do:
$ qemu-system-x86_64 -enable-kvm -drive file=arch-x86_64,if=virtio -net nic,model=virtio -net bridge,br=br0
inside the VM you'll have eth0 (or whatever), and on the host -- tap0 plugged into the bridge. This is all courtesy of /usr/lib/qemu/qemu-bridge-helper which is a suid binary.

Hyper-V can't create a network switch in Windows 8 enterprise evaluation

Hello
I have a problem with creating a new virtual network switch in windows 8.
it's the error:
[Window Title]
Virtual Switch Manager for HYPER-VISOR
[Main Instruction]
Error applying Virtual Switch Properties changes

Hi,
If you are using Wireless network adapters.
Virtual switches can only be created that are bound to wired NIC's
Best regards,

Adding network switch to external WAN to increase number of ports available

This may be a stupid question but this has kinda been landed on me so I'll ask anyway.
We have a Cisco router with ethernet connection to our provider's NTE. They provide us with one ethernet port on the NTE which we connect to the WAN port on our Cisco router. The WAN interface on our router is configured with a public IP address from the /29 subnet the provider assigned to us.
We have a 3rd party installing SIP connectivity for us and they need us to provide them with a public IP address and connectivity outside our router/firewall for their Session Border Controller (apparently NAT doesn't work well with SIP so we can't have it inside our network and NAT it via our existing router)
Since we only have one ethernet port presented to us by our provider, is this just a case of placing a network switch in between the router and the provider NTE then having our router connect to the switch and the 3rd party's Session Border Controller connect into the switch too? We can then assign another IP address from our provider's /29 to the 3rd party's kit.
Is it as simple as that or am I missing something?
If it really is that simple, are there any considerations for what sort of switch I should use? Can it be something relatively cheap and cheerful, does it even need to be a managed switch?

Is it as simple as that or am I missing something?
Should be that simple although I would check with provider ie. a switch will usually send L2 protocols on the link to the provider as well as to the router so you may want to check with them they are happy for you to do it.
Although I suspect they won't care as they don't really know how you have it connected now ie. you could already be using a switch as far as they know.
Still worth running it by them though.
You only need a L2 switch so definitely no need for L3 functionality.
Some people prefer unmanaged switches outside of their network eg. in the untrusted area.
Really up to you whether you need it managed or not.
In terms of overall functionality very little is needed but you would want something reliable as it is another single point of failure.
One last thing, if this is the only connection then nothing else to do but be aware that currently if the provider NTE fails your router knows about it because it is a direct connection. With a switch in between if either side fails the other side doesn't know because it's connection to the switch is still up.
If this is your only connection to the internet then it's not an issue but if you had an alternate path you would need to track the connection to make sure you failed over properly.

Problems with uVerse DVR connected to a network switch and 1x3 HDMI switch

So that I can connect multiple devices (Apple TV & BluRay player), I've connected my uVerse DVR to a network switch with IP Quality of Service function. Is it known whether or not this will cause problems? I am having problems, but see next question for probable cause. I have also connected my HD TV to a 1x3 HDMI switch output, with inputs from the uVerse DVR, Apple TV, & BluRay player. This clearly has caused problems because the DVR goes through the power on sequence almost everytime the TV is turned on, I have intermittent problems with the HDMI switch displaying video on the TV, and on several occassions, shows scheduled for recording haven't recorded at all or only partially recorded.

I've been having problems with this for months especially with the GigaPower rollout and broke down and decided to resort to some network engineering tactics versus calling out AT&T Techs. The Techs are good at their job but they are only knowledgeable about the hardware aspect but are dumb founded on this one and it's not their job to know. To the point of using a switch next to the DVR and this counts truly for all set top boxes via Ethernet they need to be physically seperated wires. Well, unless you want to pay someone to put an extra Ethernet drop next to each wired set-top box or DVR this isn't feasible so options are deal with it or spend $20 more dollars on a switch that supports 802.1q trunking which makes two 'virtual' independent ethernet cables over one line. If you can do it great otherwise this takes a higher than average knowledge of basic networking. A basic setup would be: + Get two switches - Netgear GS108T or GS108E I've found does the job well. + Enable 802.1q advanced VLANs+ Make two additional vlans 2 and 3 (1 is the native VLAN)+ Mark a port as tagged 'T' for the trunk port to the other switch for VLANS 1,2,3 (I used port 8)+ Assign VLAN 2 and mark as untagged for ports 2-7 - this is for data traffic+ Assign VLAN 3 and mark as untagged for port 8 only - this is for video multi-cast traffic+ ***DISABLE*** MULTI-CAST IGMP SNOPING otherwise IPTV won't work. On the back of the Uvserse router, take an Ethernet wire and plug into port 8 and take an Ethernet cable and plug into port 7. This does not create a loop though sounds like it, we've created two unique layer 2 networks. Now configure the second Netgear switch (or switch of your choosing...) the same exact way but plug your DVR into port '8' and all your data stuff XBox, whatever... into ports 2-7. Whalla, you've eliminating multi-cast flooding and DVR traffic is independent. Ever since I started doing this I increased the speed throughput from 10 MB/s or to never working to a full reliable gigabit speed or respectibly whatever UVerse service you get.

3G only network selection.

Recently one of my friend using android shown me one advantage that the can select 3g Only network. This can avoid your phone from switching between 3g and 2g and there by easier download is possible. Currently if we select 3g it will automatically select 2g if there is high signal strength for 2g is much higher than 3g. this is annoying.
I will suggest three option
3g only
2g only
3g and 2g.
Please make an update on it.

There you go …

Please, do not forget to talk to your network operator, as well, so he investigates the cell coverage and handover parameters at your location.

Network switch

I'm trying to bypass the security on the Apple Time capsule to some devices. If I where to hook a network switch to WAN port, would this allow it, and what type would I need for the speeds I get. I currently have the AC model and my ISP speeds are 130 down and 25 up. I'm having issues with my Apple Time Capsule communicating with the ADT security gateway and hopping a network switch would solve this problem since I only have one port on modem and can't connect directly to that. I've already messed with ports on router and that didn't help.

Not sure what you mean about the "security" in the Time Capsule. A wireless connection uses a type of security called WPA2, but this is standard industry setting that virtually any modem device will use.
Other than that, there are no "security" settings on a Time Capsule.
My guess would be that you are trying to say that the ADT gateway is designed to work with a router that provides a feature known as Universal Plug and Play, or UPnP, which is a service that automatically opens the correct ports for devices that are connecting to the Internet.
Unfortunately, Apple routers do not support UPnP, so your statement that you are going to have to purchase a new router may be correct.
Apples does provide a function called NAT-PMP, which allows a user to manually enter the port settings that the ADT gateway might require, but this is not always successful, since it is not the same as UPnP.
If it were me, I would ask ADT support what brand or model of router that they recommend for use with their gateway.

How do I set up my time capsule as an internal only network.

I currently have a time capsule that was attached via ethernet cable to my wireless router (Brighthouse network) and worked fine with Time Machine.
I want to disconect it from the router (no connection via ethernet cable or wireless) and configure it to be a separate network I can connet to and use to access the Time Capsule hard drive. So I want to establish a wirless base station that creates a new internal only network, not connected to the internet, that gives me access to the hard drive using Time Capsule.
I recognize that when I connet to the Timne Capsule in this configuration I would have to select it and would not be conected to the other wireless network at my house or to the internet.
Thanks for the help

Just take the TC and reset to factory..
Setup again with no WAN connection.. but leave the TC in router mode.. it will kick up a bunch of errors about having no WAN connection.. just ignore them all.
Create a wireless network.. try and use an IP address range not used by your main network.. just to help stop confusion.
When you swap between the two it should be able to work fine.

How to set up Leopard server on a wifi-only network?

Hi - I'm having a lot of trouble getting Leopard server installed and running on a wi-fi only network. Standard setup says I have to be connected to a local Ethernet. Advance setup allows me to start services, but then the server disappears after a few minutes.
Anyone able to do this successfully?

Per the documentation, there is no way to do this. Leopard Server requires a dedicated Ethernet port on the subnet that it serves - so I'll have to bridge my Ethernet and wifi networks. As I don't have a hub of my own, I'll upgrade my Airport Express to an Airport Extreme, connect the mini and see if the services come back up or if I have to reinstall.
