<title>[Other] Setting up a Home Network</title>
<link>http://www.dslreports.com/forum/remark,22655052</link>
<description><![CDATA[I am setting up my home network. I have the following equipment: Netopia 3346n-002 Modem, D-Link WBR-2310 Super G Wireless Router (108 mbs), SMC Networks EZ Net 16 port Switch. I am using the modem in bridge mode to drive the router. My question is: At which source would I plug the switch in. One of the ports of the router (seems like the logical answer) One of the ports on the modem, Could I take  the router and plug it into one of the ports on the switch? The only reason I am using the wireless router is because I use my laptop all through the house. My other computers are going to be hardwired to the switch. Is the throughput on 108 Mbs Super G that much faster? Even though the link speed is 108 mbs, it always seems that the throughput is never faster than 54 mbs. If I stick with my other Netopia 3347n-002 54mbs gateway I wont even have to use the WBR-2310. I guess what I am asking is the 108 mbs all that much faster to even bother using?

Thanks,

Marc]]></description>

<title>multiple routers, subnets, and file sharing...DHCP/WINS/DNS</title>
<link>http://www.dslreports.com/forum/remark,22654514</link>
<description><![CDATA[Hello!  I am studying for a network+ exam and I had some theoretical questions.  I've got a good grip on all of these things and what they do, and really how to use them, but the practical applications/scenarios of them in the book I am reading is a little bit on the short side.  I think I have some more advanced scenario questions than I can readily find answers to.  So, here goes.  I understand the difference between routers and bridges (layer 3 vs. layer 2) bridges filter and forward broadcasts, routers don't, they filter and forward and route based on ip address traffic and not mac address traffic (say netbios), but I do understand that windows often runs netBT (netbios over ip) which can make it through routers.  

Okay, so there's a setup of what I've learned, but when it comes to practical networking, is it possible to file-share with windows between subnets?  What I've come to is that, I think you can, if they share the same gateway, you just wouldn't be able to browse other computers,  you would have to use the ip addresses to get to each computer (because of lack of broadcasting making it over to the different subnets) unless you had a dns or wins server set up with relays in each subnet (except the one those servers were in) to keep up with host names to resolve to each of the ip addresses.  Okay, that's what I think and please correct me if I am wrong.  Or, if you can, explain why I am right!  I really don't get it, that's just what I think for now.  If that is right, could you also answer a couple of other questions that are stumping me?

What if each of these subnets had their own gateway.  Could you still ping or file share (at least based on ip address) between computers on different subnets?  Would anything be different if they were all using different gateways instead the same one?

Okay, as an example:

What if each of these subnets weren't subnetted using static ip's/subnet masks and instead each had a router with DHCP handing out their addresses (and each of these routers was on a different subnet).  They could either use one of those routers as a gateway or each use their own, right?  Okay, now that's confusing so how about a concrete example.  Say you have a two tier configuration with three routers.  A triangle.  Router #1 at the top (with the subnet 192.168.0.1) with router #2 (192.168.1.1) and router #3 (192.168.2.1) connected underneath it.  What services would be available between subnets?  (This would be if you used an ip address to access the other computers  directly or if you had a DNS/WINS server to take the place of broadcasts for resolving host names) Could a computer plugged into router #2 share files with computers plugged into router #1 and router #3?  Could they ping each other across those subnets?  Would this change if the computers, regardless of subnet, all used router #1 as the gateway (192.168.0.1) vs. if they used their individual routers as their gateway (which those routers probably are set to use router #1 as their wan gateway since it is at the top...) yet, would this make any difference?  Thank you very much for anyone who goes out of their way to try to explain this!  And please, anyone who knows more about this feel free to take it and run with it, even in all kinds of different directions as it may lead.  Thank you all very much.]]></description>

<title>Accessing DSL Modem&#x27;s web config from behind NAT router</title>
<link>http://www.dslreports.com/forum/remark,22654335</link>
<description><![CDATA[Greetings Everyone.

I am unable to access my DSL Modem's web config from behind a NAT-enabled router, was wondering if anybody had any suggestions as to how I could do this.

Here is my setup.

Zhone 6211-I3-200 Modem (configured as a bridge), with it's web config IP changed to 192.168.1.2, connected to the WAN port of a Netopia 3387WG-ENT router, configured for PPPoE, My router has an IP of 192.168.1.1 ...Connected to this router is also an Netgear 8 port managed switch (with an IP of 192.168.1.3).

This setup works perfect, and I can telnet into my switch, and router just fine, but not surprisingly, since the DSL Modem is outside of my LAN and NAT, and on the WAN side, I can't talk to it.

Do any of you know of any way of getting this to work? I would like to access my modem's web config to see such diagnostic information as error counts, etc, but I don't want to have to disconnect my router to log onto the modem.

There is one way that I know of to make it work, and that is to use my Netopia router's built in 4 port switch. If I plug the modem into one of the LAN Ports, and use another ethernet cable and connect one of the LAN ports to the WAN port my router accesses the modem via it's own built in switch, as long as I give my modem an IP on the same subnet as my other hosts. I would like to avoid wiring things up this way though.

Does anyone have any other suggestions as to how I might accomplish this task?]]></description>

<title>[Other] Linksys Incoming Log Table - What does it MEAN</title>
<link>http://www.dslreports.com/forum/remark,22654561</link>
<description><![CDATA[I have looked everywhere for this information, I cannot find a clear definition, and it is very critical to me.

My BEFSR41 Router has an Incoming Log Table that gains a new entry every few seconds, from somewhere in the world.

I do not know whether this log is indicating IP addresses of actual intruders or wannabe intruders.

Can someone with some knowledge in this area explain to me just what this list indicates?]]></description>

<title>[Other] How to fix terrible cable service?</title>
<link>http://www.dslreports.com/forum/remark,22650205</link>
<description><![CDATA[Sorry if this is in the wrong forum... I wasn't quite sure where it should go.

For the past several months, my cable internet with Northland Cable has been absolutely terrible. I'm on a 6mbps plan and I get that some of the time... but other times, it can be down to 1mbps or less for hours at a time. It also randomly kicks completely for about 30 seconds around 10-15 times a day. This may not be annoying to most of you, but I play a game called Tibia (MMORPG), and when the net kicks while I'm hunting, I can lose up to 6 hours worth of work. Also annoying as hell while trying to play Xbox Live.
I have called and complained to my ISP several times, but they always send a technician out and he tells me nothing is wrong and there isn't anything they can do.

Is there anything you guys can tell me about this situation? What might be causing this? Suggestions for ISP to fix it? I have read that them creating a new cable channel and splitting the users on this one channel could solve the problem... is this a feasible option for the ISP, or is it more work than it sounds?

Thanks for any help you guys can offer.]]></description>

<title>UPNP Setup</title>
<link>http://www.dslreports.com/forum/remark,22648435</link>
<description><![CDATA[I believe that I understand what UPNP is, but my router is confusing me. When I go to turn on UPNP in my router, it is asking me to choose an internal port, an external port, and an ip address. I thought that with UPNP you simply had to turn it on and then the devices handled all the port numbers. Why is the router asking me for all of this information? Wouldn't that be the information I would find if I wanted to configure port forwarding by myself under the port forwarding tab?]]></description>

<title>Powerline networking and VLAN tags</title>
<link>http://www.dslreports.com/forum/remark,22650680</link>
<description><![CDATA[I have a small network that I operate at a local marina. This network is composed of a router (cisco 871), a desktop, network camera and an access point.

The access point operates on a tagged vlan (VLAN 2) to isolate it from the main network. This is done because VLAN 2 has a captive portal associated with it for the wireless access. Vlan 1 is native.

I need to secure the router and cable modem as people have been tampering with it. Unfortunately, due to the design of the marina, I cannot run any new wires.

I decided to look at Powerline adapters. However I don't know if they would have the ability to pass Tagged VLAN frames.

The Homeplug 1.0 spec indicates that they support VLAN tagging, however I'm pretty sure this is only related to the communication between powerline devices for QoS purposes, and NOT for the transmisison of data over the powerline adapters.

Of course, most residental networking devices don't even list a "compliance" section so I can't look up if it supports 802.1q tagging or not.

Has anybody attempted transmitting tagged vlan frames over a set of powerline adapters?

EDIT: If these devices act as transparent bridges, I don't think I'll have a problem..... my only concern is if whether or nor it will drop a full frame (which is 1522 bytes when vlan tagged... 4 bytes bigger than the 1518 byte ethernet frame limit)]]></description>

<title>Smokeping results</title>
<link>http://www.dslreports.com/forum/remark,22649872</link>
<description><![CDATA[OK Ran smokeping on cable connection, pinging against firewall. When I click on the results it showed avg 5% packet loss on all threee stations. Fine. Clicked on each graph it shows close to 50% loss!!! on all three!! Plus it lists 3 hr 10 days etc times what are those there's no explaination! 
Now everytime I pull up results the packet loss is increasing up to 22% now! But the test is done!! I dont get what I'm looking at!
