Adding a Gigabit switch to HH2 - any point?

I currently run my home network though a 10/100 switch connected to my HH2. My son plays on-line games and watches 'on demand' TV programmes. Occasionally there's some 'stuttering' on sound and picture.
Would there be any improvement if I swapped out my 10/100 switch for a Gigabit one, or would this only affect 'internal', home network file swapping/sharing?
I've tried asking BT Technical what the speed of the ethernet ports are on the HH2...

I think you've guessed the answer already... it won't make online access any better, the bottleneck will be your broadband connection. The gigabit switches (and NICs for that matter) tend to use more power and run hotter in my experience, so I wouldn't recommend the switch unless you have a definite requirement for one.

Adding Two Gigabit Switches to Airport Extreme

I want to add an 8-port D-Link gigabit switch to my brand new Airport Extreme to network my Mac Pro, my iMac and two printers in the office. The MacBook Pro would run wirelessly. Then, I want to add a 5-port switch 100-feet away (and down another floor) to directly wire the Apple TV, the DSS tuner, the blu-ray player and maybe use my older non-n Airport Extreme to radiate in that far away room also. Sound like a plan to you wizards? :--) Or am I nuts. Using gigbit cables.

Nope just get a small ethernet to go from one of the 4 hookups on the AE to go to the switch.

Airport wifi problems with uverse and gigabit switch resolved

I think there is a bug in airport firmware 7.6 with how spanning tree works in addition to problems with the Uverse router. Having an Airport with a uverse 2wire 3801 and gigabit switch will not work. Putting the extreme in NAT mode with DMZ plus behind the uverse resolved the problem.
Network configuration:
Uverse 2wire 3801 router
    3801 provides prioritization for upstream traffic so skype and VoIP work better when doing a lot of stuff on Internet
Airport extreme firmware 7.6
two airport express 802.11n hardwired to extreme. Set up in bridge mode. All access points have same SSID "create a network" to enable roaming. Ignore anything to do with extending a network. firmware 7.6
two gigabit switches
    Netgear GS608 - 8 port gigabit switch
    Trendnet TEG-S80g - 8 port gigabit switch
    100BT 5 port switch - did not figure into problem
Three Uverse set top boxes wired on Ethernet. They have to be wire directly to the 2wire box to work correctly. See: http://forums.att.com/t5/Features-and-How-To/At-amp-t-U-Verse-modem-setup-Airpor t-Extreme/td-p/2300785
However, you need to be careful to place your own PCs and other internet devices on the network created by your gear (airport extreme in your case), but keep AT&T's set top boxes for the IPTV services IN FRONT of your own router - so they remain on AT&T's provided network.
So it would work like this ...
Network 1: 2wire RG (4 lan ports) -> Any Set tops, and to the WAN port on your AirportExtreme
Network 2: Airport Extreme LAN ports -> to any computers or internet devices (but not AT&T set top boxes).
The RG prioritizes the traffic for your Uverse Voice and your Uverse TV ahead of internet data traffic, as it rationalizes data heading out of your home. If you place your own equipment in that equation (like putting AT&T set top boxes behind your Airport Extreme) the performance and function of your AT&T set top boxes could really flake out on you.
Symptom:
    Everything would be working fine, then intermittently all my wifi access points would stop working. ~6,000 ms latency, dropped packets. Ethernet worked fine. Here is an example of my macbook pinging the extreme when associated with the extreme over wifi with a strong signal.

64 bytes from 192.168.1.64: icmp_seq=36 ttl=255 time=39.828 ms
Root cause:
    It looks like the 2wire 2801 router has a problem with spanning tree when interoperating with gigabit switches and airports. There is interplay with the airport.
I did not have this problem until the 7.6 airport firmware. I had been using the Netgear hub for about a year with the extreme in bridge mode. I added the Trendnet hub and upgraded airport firmware at the same time which made fault isolation difficult.
Problem recreation:
Set up airport expresses hard wired to extreme
Connect gigabit switch anywhere to network
Everything OK
Dettach one computer from wifi then reattach, then all wifi stops working. It takes a few seconds for the problem to propagate.
Ethernet still works fine
Problem Resolution:
Connect to 2wire with ethernet
Set 2wire route to have subnet as 192.168.2.x
Set extreme in NAT mode behind 2wire. It will complain about double NAT. Override the warning. Set the subnet to 192.168.1.x so you don't have to change any static IP addresses. Note that 2wire uses 192.168.1.254 as default route whereas airport uses 192.168.1.1.
I set DHCP to start at .10 to leave the lower addresses for assigning static IP addresses to computers I want to expose outside the firewall.
Go into firewall settings. Select airport extreme. Select the bottom setting which is "DMZ Plus". When you go into the airport extreme settings, you will now see that it has the uverse public IP address on its WAN port. NAT port mappings work fine on the extreme behind the 2wire router.

Keeping this very short here is a summary of the actual problem and solution to allow your Apple Airport Extreme to run in Bridge mode on the same subnet as your uVerse settop boxes (if your Layer 2 switch is configurable).
Devices: Uverse, Cisco SG300, and Airport Extreme
uVerse uses Multicast to broadcast video streams between the uVerse network to the settop box, and from settop box to settop box.
X number of Multicast Groups are created based on X number of settop boxes you have. You can see the multicast definitions by logging into the webinterface of the iNid. Each settop box is a member and can choose to display a broadcasted TV stream or not.
Multicast membership is setup by the use of ICMP messages for IPv4 (MLD for IPv6). Each of the settop boxes become members of each others multicast group by reporting up to the iNid (MultiCast Proxy).
In an ideal world a layer 2 switch will track these memberships and only forward a broadcast packet to the ports on the switch to which the settop boxes are connected to. The switch would do these via snooping on the ICMP packets. Most switches by default do not do this by default and simply forward the broadcast packett out every one of it's switch ports.
Here in lies the problem. Problem is that the Apple AES doesn’t do ICMP snooping / filtering and floods the wireless network with these broadcast streams.
In order to fix this you must turn on ICMP snooping and filtering on the switch (or buy a switch that does this). I have a Cisco SG300 and list out the configuration below.
Other notes:
Ensure that all Media renderers (settop boxes) and servers are wired directly off the switch and not attached to any of the Airport Express ports. This way no media transverses the Airport (only control point traffic goes through the WiFi - which is fine). Obviously if the IGMP snooping switch sees any client requesting Multicast streaming traffic on the same port as the WAP, it will add that Multicast address to the forwarding table for that port, and then, yes it could get flooded.
Remember, you need to allow some Multicast traffic through your WAP to allow UPnP discovery to work (assuming that you will be using Wireless control points.)
Read the Multicast chapter in the SG 300 switch Admin Guide as it explains things very well.
Setting up multicast on the SG300s using the WebUI:
1. Multicast/Properties/
Tick enable Bridge Multicast Filtering Status for VLAN 1, and
set the Forwarding Method to IP Group Address for both IPv4 & IPv6.
2. Multicast/ IGMP snooping/
Tick enable IGMP snooping status then select and edit the entry and ensure that IGMP querier status is ticked.
It's essential for IGMP snooping to work that there must be at least one active IGMP querier on the network - if more than one is enabled, they will carry out an "election" to decide which one should be active (normally the one with the lowest IP address.)
3. Multicast Router Port
Set whichever port that is connected to the uVerse iNid to Status which means that it the uVerse router connected to this port is the Multicast Router
4. Multicast/ Unregistered Multicast
set all ports to Filtering. (The default is Forwarding.)
There are a lot of other variables within all the above - the defaults are OK, you should probably leave them alone!
In the config file you would then expect to see the above appearing as something like this:
ip igmp snooping
ip igmp snooping vlan 1
ip igmp snooping vlan 1 immediate-leave
interface vlan 1
bridge multicast mode ipv4-group
bridge multicast ipv6 mode ip-group
interface range gi1-10
bridge multicast unregistered filtering
ip igmp snooping vlan 1 querier
ip igmp snooping vlan 1 querier address <IP-Addr>

Adding a NetGear Switch

I have more devices than ports. Is adding a NetGear switch just a matter of plugging it in and turning it on?

I have a Netgear DGN2000 as my modem/router with wifi. I previously had an Edimax wireless access point at the other end of my rather long, thin house. It was connected via ethernet and via a switch (also used to connect my printer and iMac to the network). It all worked fine but I wanted to use a time capsule for back-ups so I replaced the Edimax with an Airport Extreme TC. Also connected via ethernet/switch in the same configuration above, including identical wireless network name and password. Took a bit of doing but once I realised it needed to be in bridge mode it seemed OK and it was possible to move seamlessly from the Netgear range to the AE/TC wireless range (although sometimes I had to switch off wifi on my iPad to make it log on to the stronger signal from the nearer of the two wifis).
The problem I have is that, initially every week or so and now every few days, the AE "spur" stops working: not nly can I not then access the internet via the AE's wifi, also the other devices connected on the same switch can no longer access the internet. The relevant LAN port light(s) on the Netgear also go out (or, sometimes, turn amber). It also crashes my (fairly extensive) Sonos network, most of which is wireless but some parts of which connect by ethernet.
I can usually fix it by restarting either or both of the AE or the Netgear but there is clearly something wrong in my set-up.
Any ideas, or should I just give up, reinstate my Edimax and try and just use the TC as an external hard drive (if so, how do I switch off the wifi?).
I noticed in the thread above that the switch was on the other side of the AE, rather than it being one of the devices connected via the switch - is that what I'm doing wrong?

Linksys Cisco SRW248G4P 48-port 10/100 + 4-port Gigabit Switch Help

The switch which is a Linksys Cisco SRW248G4P 48-port 10/100 + 4-port Gigabit Switch, was configured by a contractor which was long ago run off, and the documentation left behind to log into the switch is incorrect. How can we reset this switch so we can configure to the new required settings?
I have attempted to go in through the web browser gui, and no luck logging in via factory default creditials, cannot log in using any of the common admin creditials, nor can we get in via the documented admin name and pw the contractor left.
Attempted ot go in through the console, that doesn't work right at all. Takes 15-20 min before I start even seeing user name or password boxes. Cannot type a single thing into those boxes. I have set the hyperterminal to com1, 38400, 8, none, 1, hardware. It kinda lets me see some of the log in screen, but will not let me type into the username whatsoever.
Logging via web browser I see all the login option but not a single username or pw works. Please if anyone can help, this has been an issue which is now critical.

Hi, My name is Eric Moyers. I am a Network Support Engineer in the Cisco Small Business Support Center.
The settings for connection using Hyperterminal through the Console port should be:
Bits per second: 38400
Databits: 8
Pairity: None
Stop bits: 1
Flow Control: None
When you finish configuring the HyperTerminal, the Login screen appears. The first time you open the Console Interface, use the default username admin and leave the password blank and press the Enter key. You can set a password later from the User and Password Settings screen.The Main Menu screen displays six menu choices: System Configuration Menu, Port Status, Port Configuration, PoE Configuration, Help, and Log Out.
User and Password Settings, IP Configuration, File Management, Restore System Default Settings, Reboot System and Back to Main Menu.
To restore the Switch back to the factory default settings, select Restore System Default Setting and press Enter. A confirmation message appears asking Are you sure? [Y/N]. Press the Y key to continue or the N key to cancel the action.
System Configuration Menu options: (Which is where you will need to go) consist of: System Configuration, Management Settings
After pressing Y, at this point reboot your system and it will be back to Factory Fresh.
If you have any questions or this doesn't work, please let me know. I am attachng the Admin Guide for you as well.

New 150/65 only at 94 Download AND Won't Work with Gigabit Switch

I just had this installed today, converting up from the 35/35, and ran into these two problems:
1. The 150 download is only resulting in a 94.87 Mpbs. The installer originally said it must be my PC NIC card, but I do have a GB card, so there's does not appear to be legitimate reason for the shortfall there. I tried to change the link speed and duplex from "auto negotation" to "1 Gbps Full Duplex," but then my computer no longer even could connect.
2. The second issue is that I have always run my connection through a D-Link DGS-2208 Gigabit Switch because I have multiple wired ethernet computers in my office. The installer wanted to test the connection speed directly through my computer (see above) and ran into problems, so I never even tried to revert to my original setup with the switch until he left. However, when I did the Gigabit switch does not even recognize any activity when I plug the source ethernet cord into the switch. It does recognize the connection to the PC and the port is lit, but no lights from connection to the wall.
Any thoughts on what the problems could be? I've included the "additional details" from the Fios Speed test at the standard site (can't get any details from the high speed version):

If your computer can't negotiate a 1Gbps connection, then that is what is limiting you to 94Mbps, which is about right for a "100Mbps" port.
There could be several reasons for this.
A bad NIC
A bad port on the switch
IMO, the most likely cause is a bad cable. 1Gbps requires all 4 pairs in the cable be connected. If only 2 of the 4 pairs are connected correctly, you will get a 100Mbps connect, but will not be able to connect at 1Gbps. Try replacing the cable with one known to work at 1Gbps.

G5 imac wont connect to gigabit switch at 1000

Hi,
I've got a G5 imac that wont connect to my gigabit switch at 1000. It looks like it connects at that speed for a few seconds then it drops to 100. I have a new Macbook pro that can easily connect at 1000 using that exact same cable.
Has anyone heard of any gigabit issues with G5 imacs?
Thanks,
Scott

I am now pretty sure it is the imac ethernet port. Connected the imac and mini together and eventually it set itself to 100Mbs.
Now trying to decide if it is worth getting fixed or just dealing with it only connecting at 100Mbs.
Thanks

Alex just a quick response to your advice re disabling AV, this did not work for me, after more searching the internet for a solution I found a post from 2013 where one poster offered the advice to go one step further, and it was to remove the AV package
completely, the package in question was KIS2013. I have KIS2015 and figured I would try it as I was getting a little frustrated with the constant failure to create a virtual switch.
Anyway, it worked for me, I removed KIS, rebooted, and the VS was created on the first attempt without any issue. So simply pausing/disabling the AV from within the AV program may not be enough, I suspect that some may work and others not, as in the case
of KIS. I wonder also if you disable the AV services at start-up if this would also work but I did not try it.
Anyway to other people experiencing this issue, I suggest disabling AV first as per Alex's advice, and if this does not work for you then suggest trying to remove the AV before doing anything more drastic like re-installation of OS as I have seen suggested
in more than one place.
Thanks
Mr Bee
--EDIT--
Just wanted to add, it is also worth 'excluding' any Hyper-V folders from the AV engine, I did not try this before removing KIS2015 so it may work without the need to remove your AV product, but on re-install I have now exluded the folders as suggest by
a few folks in various posts...

My ethenet LAN slows down when I use a (supposedly) faster gigabit switch.

I am using the latest version Airport router. It is providing our home wireless network, which is working fine. I also have a home ethernet LAN. The Airport is connected to an old, cheap, no-name 100Mb switch. I decided to try a Netgear GS608v3 gigabit switch to see if it would allow faster ethernet LAN (of course I understand that it has no effect whatsoever on the WiFi network). The indicator light for the port where the cable from the Airport plugs into the swich glows yellow, indicating only Mb speed. The indicator lights for the other ports running cables to my wired devices all glow green, indicating a gigabit connection.
When using my web browser, I was expecting that I would not really be able to see any differences, but to my surprise the new Netgear gigabit switch was associated with dramatically SLOWER web page load times. And I mean s-l-o-w. Something is wrong here. It should be as fast or faster. And why is the input from the Airport router indicating only 100mb speed?

the problem is with the Netgear switch for SURE. you can not have packet loss on internal network.
going further:
You can troubleshoot this problem. but will take a while.
using the finder, go to network utility and select your ethernet connection,
on right side you will see Transfer statistics
if send errors or recv errors or collision are being incremented you have a problem between your mac and the switch port, (you can have problem from the switch to the router too).
In order to resolve this problem:
system preference
network
selecet ethernet
select last tab (Ethernet)
configure: manually
set speed to 100baseTX
duplex to full duplex, flow-control.
ok
apply
repeat the ping test
you can reach airport page and check for errors on lan ports.
more one tip: you need use CAT5e cables, read the cable and post the results

Connecting two linksys gigabit switches

Hi,
I just bought a slm2024 (24 port managed Gigbabit switch) to replace an older 100Mbit switch. The old switch had PCs and other switches connected to it. The other switches are EG005W ver. 3. (linksys workgroup 5 port gigabit switches)
With the new slm2024 switch, the PCs have no problems connecting. The problem is the EG005W switches. The port on the slm2024 which connects both switches is dark (the LED is dark - no lights at all). Any thoughts on what is the problem? Do I need to configure something special on the slm2024?
I do have an older 100Mbit switch and if I connect it to the new slm2024 switch, the lights are on and traffic is flowing. It is just the EG005W that does not seem to like being plugged in the gigabit switch. It used to work when plugged in the older 100Mbit switch.
Oh and if I try to plug in two EG005W together, I get the same problem. PCs connected to the 2nd switch cannot communicate out either.
I understand that in the past cross-over cables where needed to connect switches but I thought that new switches no longer require this (even my old 100Mbit switch did not require this for the EG005W to work through it).
Any thoughts on how to fix or debug this?
Thanks for any suggestions.

there shouldn't be any configuration needed on the ports of the SLM2024 because they are already "smart ports"
this could be a possible problem between these 2 devices -- have heard of similar problem before bet. a switch and hub but i have forgotten their model numbers -- you would think that since they came from the same manufacturer you will have an easier set-up but sometimes that's just not the case

Using 2 gigabit switches on Airport Extreme N

I'm really trying to work around the 10/100 LAN ports of the AEn and am using a Gigabit switch in order to allow my GigE Mac Pro, Intel Mac Mini, Macbook and ReadyNAS NV connections to each other (thus maxminizing network transfer speeds).
The problem is I have the ReadyNAS in another room (noise) plus needed to run more wired Ethernet to an Xbox 360. In order to save multiple cable runs, this is how I'm set up:
[ Airport Extreme ] in the office
LAN port hooked to Netgear GigE switch
|
|
[Netgear 8 port GigE switch GS108] in the office
ports hooked to:
- Mac Pro
- Intel Mac Mini
- MacBook
- cable through office wall to laundry room, connected to Dlink 5 port GigE switch
|
== wall to laundry room ====
|
[Dlink 5 port GigE DGS-1005D] in laundry room
- ReadyNAS NV
- Another server Dell PC
- Xbox 360 (via cable through another wall to gym)
Questions:
Does this configuration make each GigE capabale device send data to others at GigE speeds (eg. MacPro to ReadyNAS, MacPro to Mac Mini, etc)?
Is there any latency or collisions caused by this configuration? I just seems to me that the ReadyNAS works much slower when hooked to the other switch vs directly to the Linksys switch but I don't have a formal testing program. Note both switches report they are Jumbo frame compatable and all gigE devices are lighting up as GigE on the switches, and all are connected with cat5e cable.
Thanks...

Does this configuration make each GigE
capabale device send data to others at GigE speeds
(eg. MacPro to ReadyNAS, MacPro to Mac Mini,
etc)?
Yes, they are all Gigabit, but if you have multiple transfers going on at once, you are limited to the speed of the backplane of the switch.
Is
there any latency or collisions caused by this
configuration?
Prehaps a crossover cable between the switches would help. In the old days you would have had to do that, but the ports are now figuring it out on their own. It might just be more efficent go by a crossover cable (looks just like a ethernet cable but has one of the internal pairs crossed, I think- that's the idea anyway.)

Do I need a Gigabit switch?

The Apple Extreme has 4 ports (all gigabit switch) and I'm only using 2 ports. I have two Mac Pro's connected to the ports and using them to record music and transfer files.
If I purchased a Netgear GS-105 gigabit switch and connect it to the Apple Extreme, would it better my network speed, or is the Apple Extreme enough?
Thanks!

I'm sure they meant well, but were not aware that electrically, everything passes through the same point in the router.
If you have the 5 port switch connected to the AirPort Extreme, you have an AirPort Extreme with 6 available LAN ports.
If you disconnect the switch, you have have an AirPort Extreme with 3 LAN ports.
If you subscribe to the theory that simpler is better, then for now, you would want to go with the 3 LAN ports on the AirPort Extreme. If you like the extra flexibility of additional ethernet ports, you could leave the switch connected for use by future additional ethernet devices.

There won't be a small business switch which is gigabit without a fan.
All models;
SG300
SG500
SGE2010
SRW2048
All mentioned units are the small business 48 port units, they all include fans.
You may consider SG300-28 or SG500-28 for gig swithches without fans.

Gigabit Switch

I just picked up a AE Gigabit edition. So far so good. Anyway, on our old network I was using a Netgear Gigabit switch with a Mac Pro and a Brother Laser Printer that was connected to it. The rest of the computers (Powerbooks and Macbooks) were wireless, using the old UFO style Airport (G). Just wondering if I still need to use the network switch or the can new AE Gigabit can balance everything out. Our network activity consists of streaming music via iTunes (air tunes), some large files transfers, email and internet. Any help or suggestions are welcome. Thanks.

You could continue to use the switch and connect it to one of the LAN ports on the AirPort Extreme base station (AEBS).
If you have 3 or less Ethernet devices you could get rid of the switch and connect the devices directly to the AEBS.

Adding a Gigabit switch to HH2 - any point?
