Router/Hub Questions

My apologies in advance for such a lack of knowledge on these things but I am still trying to connect a pc and this mac to the same high speed wireless modem and also share files.
First I tried using the ethernet connections on the back of the mac, plugging one into the modem and the other into the pc. Worked intermittently.
Then I purchased a linksys 5 port network hub from Wally World, thinking that would make it work. Just plugged everything into the first 3 ports and it worked but still intermittently. For high speed, it sometimes takes a long time to react and sometimes not.
So I don't know at this point where the sticking point is.
They still won't share files.
All help greatly appreciated...

What you need is a router/gateway. Not sure if the LinkSys product you have is a router or a switch - sounds like the latter. But what you need is a router.
A router will have one WAN port and one or more LAN ports depending upon what you purchase. You will want one that has enough LAN ports for each device you want to connect in the network (computers, printers, phones, etc.)
The cable modem's Ethernet port is connected to the WAN port. Each computer is connected to a LAN port. Each computer's Network preferences are configured for Built-in Ethernet and using DHCP.
After physically connecting everything you should shut off the computers, modem, and router. Wait one minute or more. First, turn on the modem and wait for the status lites to show you are connected to the ISP. Then turn on the router and wait until the status lite shows it's communicating with the modem. Last turn on the computers. If all goes well the computers should each be connected to the internet.
To share files read over the following articles:

Help.....BT Home Hub question

Hello, I am a new member and hope someone may be able to help me.
I have a BT Home Hub 2 but unfortunately the wireless signal is not making it around the whole house, and this is even with a wireless extender fitted in another part of the house.
My question is, as I have 2 old routers, a netgear DG 834 and also a Speedtouch 330 (USB modem) is it possible to hook up two routers/adsl modems to a single BT line in order to get signals in different parts of the house. If this is possible, I would plug my wifi extender by hardwire into the second router and hopefully sort the problems I am suffering with. I am not very techie, but know a little.
Many thanks
Peter

Wireless Router/Networking question

Could post this in any number of forums here as my computer inventory includes a MDD with wireless card and a Sawtooth connected direct to the ethernet hub which in turn is connected to my Qwest DSL wireless router. Have a couple others wired in as well a cube and a FP iMac 800 (one of the originals). And now my first laptop ... MBP 2.4Ghz.
Anyway, the question is this .... Can I replace the Qwest DSL router with one that provides 'n' wireless speed so the MBP can benefit from it? If so, any recommendations for a router?
Just another sentence about my set up ... The router is wired/wireless. Computers without wireless connect via ethernet, computers with wireless connect wirelessly (of course - duh).
Thank you

Yes, you can do that. The n wireless router will have to run in mixed g/n mode, which will reduce the actual speeds attained on the MBP (lower than an n-only network, but the reduction will not be to g-wireless speeds).
Having stated that, keep in mind that unless you are running local wireless file transfers (think backing up to Time Capsule here), there's no need for n-wireless. In other words, a home wireless network is not the bottleneck for internet access, it's your ISP.
Verizon just announced 50 mbps with their FIOS service (with a hefty premium cost), and that's the fastest available home internet connection, and it's still slower than even 802.11g (54 mbps). Typical home internet connections are in the 1-10 mbps range, and so even an 802.11b network is faster.
Hope this helps...

Router security question

Hi,
I have recently connected a Linksys router (WRT54GC) via ethernet cables between my cable modem and my iMac C2D.
Also, I connected an iMac G3 (upstairs) to that router via ethernet wall-plug adapters.
Basically, this wireless router is being used as a wired router or ethernet hub.
I did not configure the iMacs or the router. I just plugged everything into the appropriate ports and it works. I have NOT tried to connect wirelessly, nor is AirPort turned on in my iMac C2D.
My question is: am I still vulnerable to someone connecting to my computers wirelessly through the Linksys? Should I configure the router for security protection?
I'm afraid to touch anything because it actually works!
Any advice on this matter would be appreciated.

If you've set up the router with a decent password and turned-off SSID broadcasts, then it's unlikely someone will be able to access your network via the wireless access.
However, if it's running with an out-of-the-box config, then it's a possibility.

Cisco ASA 5505 VPN Routing/Networking Question

I have a very basic question about Cisco ASA 5505 IPsec Site to Site VPNs. I want to install a Cisco ASA 5505 at a Data Center, in a LAN subnet that utilizes publicly routable IP addresses. I would like to install a second Cisco ASA 5505 in a remote branch office as its peer.
Regardless of whether I use publicly routable IPs at the branch office in the "inside" network or non-routable IPs, how would the devices and servers at the Data Center know to route IP packets destined for the branch office back through the Cisco ASA instead of through the default gateway at the Data Center? I can see accomplishing this if every single device at the Data Center is configured with routing table entries, but that isn't feasible. It also isn't feasible to use the Cisco ASA 5505 as the default gateway for all of the devices as the Data Center, allowing it to decide where the traffic should go.
What am I missing? Is the solution to try to map branch office IPs to IP addresses within the Data Center's LAN subnet so that all of the traffic is on the same subnet?

You can do it in several different ways.
One way is to tell the server that if it has traffic to network x then it needs to go to the ASA all other traffic is to head for the default gateway.
In windows this is done via the route command
do not forget to make it "persistent" otherwise the route will disapear when your reboot the server.
in unix/linux
It is also the route command
Or you can tell your "default gateway" to route that network to the ASA
Good luck

Visual Hub questions (related to Apple TV) and others

Hey guys,
Just bought Visual Hub to convert my stuff.
What do you recommend for the settings ?
Right now this is what I use : (NOTE : I translated on the fly from french so maybe it's a bit different)
-To : iTunes
-Optimize for : Apple TV 5.1
-Quality : BIG QUESTION HERE : I want as close as 1080p as can be, but if the source file I'm -converting is poor quality, won't this make a big file for nothing ? What should I base my choice on?
-H.264 enabled
-In advanced, I select double-pass and deinterlace, audio settings = initial
Nothing else is tweaked in advanced
so what do you think ?
I have a couple of other questions :
- What if I deinterlace a video that is not interlaced in the beginning ?
- How can I determine if a video is interlaced ?
- How can I tell if a video is in 5.1 or even full HD ?
- How can I make sure to get 5.1 on my Apple TV
- Can Apple TV play 1080p ? or is it just upscaling ?
- If A TV can output 1080p, where can I find sources file of such quality ?
Anything else that I should know of related to my questions ?
Thanks guys !!

I don't use visualhub so I couldn't suggest settings for you, but.
but if the source file I'm -converting is poor quality, won't this make a big file for nothing
Yes, that's all it will do.
What if I deinterlace a video that is not interlaced in the beginning ?
You will lose detail
How can I determine if a video is interlaced ?
Take a look at it on a progressive scan display such as your mac monitor, you will see horizontal lines in high motion areas when paused.
How can I tell if a video is in 5.1 or even full HD ?
See This
How can I make sure to get 5.1 on my Apple TV
Your content file need to have an AC3 track and you will need to play the audio through a 5.1 capable receiver or home theatre system.
Can Apple TV play 1080p ? or is it just upscaling ?
It can play up to 720p after which it upscales.
If A TV can output 1080p, where can I find sources file of such quality ?
More or less nowhere.

Wireless Router WAN Question

I currently have a WRT600N wireless router. This router allows me to release the WAN IP and get a new IP. It may rotate through what ever my service provider is offering but it is always different at least 4 times in a row. I have another cable connection upstairs and a different type of router. This router does not get a new IP when I do a ipconfig /release, instead, it will get the same ip back all day long.
I put the WRT600N on the upstairs cable modem and got the results I expected based on what I saw downstairs. So my question is, If I am looking for a new router for the upstairs connection, what spefically would I be looking for that allows the router to get a new IP everytime I disconnect and reconnect. I am looking for an alternative to the WRT600N or a location to purchase the WRT600N.
Again, I am talking about the WAN port, not the LAN port. I know that some service providers lock the IP down by MAC, but that is not the case in my situation.
Thanks in Advance,
Brandon

OK, one more time, in better english. I have a computer and a WRT600N on on cable modem. And I have a computer and a WRT54G on another cable modem. When I access the http server of the WRT600N via a web browser and release the WAN interface IP, and then renew it, I get a new IP address. I can do this over and over and I get a new IP everytime.
From the other computer, I access the http server of the WRT54G via a web browser and release the WAN interface IP, and then renew it, I get the same IP address. I can do this over and over and I get the same IP everytime.
When I move the WRT600N to the upstairs cable modem, I get a different IP everytime I release and renew the IP address (Via the web interface of the router).
So I know that it is some capability of this particular router. The cable modem accounts are from the same company. So my question was, "What is it in this particular router that allows the WAN interface to get a new IP everytime it release and renews?".
I know how DHCP works, and how ISP can sometimes lock an IP to a MAC address for a period of hours, or indefinetly. However, that is not the case in my situation. If you do not know what allows this particular router to get a new and different IP each time it connects that is ok.
I can not make this any clearer.
Thanks,
Brandon

Route distinguisher question

Hi,
I need to clear some concept regarding rd, i had a topology from one of the COD in which instructor connects 2 CE sites to each other using VPN_A but at one PE the configured RD was different and at another PE RD was different. The thing which connected both the CE sites was the same import/export RT.
Previously i knew that RD should be unique per customer then y did the instructor configured different RD for the same VPN. i.e VPN_A.
Next question is that is the Vrf name i.e VPN_A in this case locally significant on the router?

Hi,
RD is used for the sake of address space overlapping (by constructing unique VPNv4 routes; in the RD:IPv4 format) and also as a VRF identifier (on the PE and the RR the VRF is identified by the RD, accordingly the RD is a mandatory attribute for the VRF configuration), and it is only significant on the PEs and RRs if exists.
Accordingly, the RD for a certain VRF needs not be the same allover the MPLS domain, RT will be used to import and export prefixes between VRFs on different PEs, lets discuss how it really happens in order for you to be able to connect the pieces together; MP-BGP exchanges the VPNv4 (RD:IPv4) prefixes between the PEs (P routers are not VPNv4 aware) not IPv4 routes - When a PE receives a VPNv4 route it discards the RD attached to it and attaches its local RD (according to the VRF that the route is going to be injected into according to the attached RT and the local VRFs import RT) - Since for the local router routing table database the VRF is identified via the RD prepended to the IPv4 route to construct the VPNv4 routes.
With the same logic the VRF name is locally significant to the PE (it maps to a RD on the local PE, while having no significance on a RR, the RR only understands RDs), it is introduced to make things user friendly, rather than using the RD solely to identifying the VRF when doing configurations and with show commands - Most commonly the same VRF name is used on all PEs (with each PE having its own RD for this VRF in the format IP:number, where IP is the PE loopback and the number is a locally unique number).
I hope that i've been informative.

Mohammed Mahmoud.

MacBookPro - USB devices/HUB question... thank you

I am a new Mac user... and I love it so far. I have the new MacBook Pro and purchased the Airport Express and a Belkin USB hub along with it. I have the USB hub connected to a USB port in my computer (and a few externals connected to that: mouse, external LaCie hard drive, etc.). My question is, when I want to go wireless and move the computer to a different location... how do I safely/properly disconnect the USB Hub? If I just pull it out (gently, of course) I get a window popup that says something along the lines of "device was not properly/safely disconnected... etc." I don't want to cause any short or long-term damage. I just want to know the proper way to disconnect USB devices (hubs, mouse, external hard drive, etc.) before using the wireless feature of the notebook.
Thanks!

Bob,
You're awesome, thanks! I tried that (pulled the external HD icon to the trash) then pulled out the USB from the Macbook and didn't get that "warning" box! I am currently only using two peripherals in my hub (a printer and the LaCie hard drive)... will I only need to do this "eject" thing for the external HDs? Or are there any other peripherals (I might use in future) that I will need to do this for as well?
Thank you again!!

Route plan question

We have two offices that will be consolidated in to one office within the same city. The existing offices are in the same area code. The new office will be in a different area code. According to ATT, the DIDs cannot be ported to the new office.
Each office has its own Route Plan (in Call Manager) and voice gateway.
For the new office, we will be installing a single Cisco 2851 for the VG/PRI and a Cisco 2951 for the data network (via MPLS). We want the network and telecommunications ready before staff move in to the new office.
My question is, can we or should we re-configure the existing route plans to reflect the new circuit/DIDs? Should we create a new route plan? What would be the best course of action for this move?
I don't have a lot of experience with route plans and VG setups so we plan on engaging a contractor for this project.
Any comment or suggestions you may have will be greatly appreciated.
Thanks!

Hey Richard,
Personally, I would create another dialplan and then use the bat tool to move the phones from one dialplan to another as the changes are made. If you're not experienced with doing this, I would concur with your decision to hire outside help to do this.
On another note, you could easily use a single 2951 for both the voice gateway and the mpls router. These isrs are made to serve double duty.

Rick

WiFi router location question.

When you move your wifi router and it shows the old address how does it learn the new address. Can you speed up the process or does it just take time ?
See also a similar question to help another person. Thank you. Happy New Year.
Hi, I have recently moved home and changed my details in my Apple ID but when using find friends or the maps app I am still located at my previous address, can you help ?

If you have the WiFi-only iPad (which does not have GPS) your location is determined by the mapped location of nearby WiFi routers.
Without GPS location-finding is done by using a Apple location database which contains the MAC addresses of routers and their physical location. A MAC address is a unique number which is built-in to all network devices when manufactured.
The Apple database is built and updated by Apple GPS-enabled devices (primarily iPhones) actually seeing routers and then adding/updating the router's locations into the database. Apple does not provide an user-accessible interface to manually update the database.
Note that to be used for location determination, a device does not need to be actually connected to a router, it just has to see the router. More precise location determination can be done if several nearby routers can be seen. When a router is moved from one location to another erroneous locations can sometimes be reported until the router's location is corrected in Apple's database.

AE Base and Hub Question...HELP!

I have an iMac connected to a hub along with my printer. I bought an AE Base Station for wireless internet for my iBook upstairs. I want to keep my iMac wired to the hub but connect the base station so the iBook can connect to the internet. THIS IS SUPPOSED TO BE SIMPLE!!!!!! I connected my cable modem to the hub and connected my iMac and the Base Station to the hub. I DOESN'T WORK!!!!! What am I doing wrong?????

A hub is not the proper device to share an internet connection. You need a router like the AirPort Extreme base station (AEBS).
You need to connect the equipment like this:
cable modem->[WAN] AEBS [LAN]->hub
Make sure that your AEBS is configured to distribute IP addresses. All of your devices will get an IP address from the AEBS.

Router/PVST question...

Using NetLabs (from NetAcademy) I hav3 a 2621 Fa0/0 hooked up to a virtual PC using VMware. When I ran a packet sniffer on the virtual pc (troubleshooting a different problem) I saw some PVST+ packets ... the only cable/NIC on this PC is coming from the FA0/0 of the router...my question is why would I be seeing spanning tree packets from from a router?
The config on the router is nothing fancy,
int fa0/0
ip address blah blah
dupl auto
speed auto
Thanks,
Jimmy

Hello Jimmy,
real world routers never generate PVST BPDUs, with special configurations (like L2TPV3) they can propagate them in some form of L2 transport over an IP network.
Routers can generate their own BPDUs but of type IEEE 802.1D when configured for Routing and Bridging (IRB).
My guess is that the system use a "switch object" to connect the three routers and the virtual PC to the same vlan (4 ports of a vlan) and it is this object that generates the PVST+ frames you see on the virtual PC port.
Hope to help
Giuseppe

New Router Hub 3 & Broadband Monitor Suggests High...

I have just replaced my ADSL Voyager router with a BT Hub type 3.
I am a low Broadband user, about, 0.25/day but checking the usage monitor today my usage per day for July has increased to 0.3/ day
Has the hub caused this or have BT a problem?
How do I evaluate?

Im reviving this thread, so far from the phone box upstairs Ive shortened the cable, It still goes into my room but now instead of having a ridiculous 15m amount of calbing unused Its a straight 3m from the other room to mine.
This has slightly improoved things.
However the hub still suffers and drops the broadband connection when under "stress" when the phone rings it sometimes drops, and when downloading files it drops halfway through if the file is large which is a massive pain.
On the downstairs master socket I removed the facia and did a quiet line test on the inside socket, there was no noise. I used a corded phone. I wasnt sure if it mattered but I tested all other sockets using this method and none had any noise.
I phoned BT and was advised to take the hub closest to the master socket, but if i do this I have no wireless card in my PC so cannot connect, The obvious option is to get a wireless card but that will cost money. As will buying the power lines.
Any suggestions? I guess plugging the hub in downstairs and trying to connect to something is the best option.
Any advice please?
