Stupid Question. Need an answer fast!


Recommended Posts

Today we are getting a new internet provider in our offices. The guy tells me that after he sets up everything i need to change my internet connection type on my router to use a Static IP instead of DHCP. I thought DHCP was only for the local IP's? Since we are getting a static IP do i also have to change the connection type to static or can i leave it the way it is now?

you will need to change it to static and insert the info he gives you. no dhcp=no address handed to you=you need to manually enter it in.

dhcp is not for just local addresses.

I see. Alright. But this will not mess up anything in my network correct?

Nope, that is handling your outside connection. The internal network setup is handled in a different part of the router configuration. Internally you will not even notice a change.

There are two things going on.

One is DHCP being pulled for the external internet address. That is what you are changing to static.

The other, what you are referring to, is the router being a DHCP server on your LAN. This is independent of the external configuration.

dhcp should be still set on the lan side. you should only be setting your wan or internet side to static. the screenshot that you posted is the only area that should change. you may want to put in the new dns servers into your forwards on your server unless you are using a public dns like opendns.

Wow that cleared it all up. Thanks a lot. The reason why we are upgrading is because we are getting VoIP phones so we need a much better connection than we currently have. The technician thats installing the new connection also said that i should get a gigabit router so the connection flows better. Anyone know any good gigabit routers up to $200?

Thanks!

What is this new connection speed? I highly doubt its over 100mbit -- so why would you need a gigabit router?

Now for a company connection the use of a wrt54g2 seems out of place to be sure. What are the details of your connection? A wrt54g2 is a home router, sure for a small office (ma and pop type setup it would be fine) but with a real business connection is not really up to snuff, etc. It can work sure - but got to love a company has a $200 budget for their gateway router?

So your going VOIP phones with what type of connection?

honestly, I would be looking at more of a higher end device than a soho router. Cisco ASA, Sonicwall, Netscreen, but all of these will cost more than your 200 limit. The cisco is not entry level friendly it is cli based so you have to know the right commands.

They said I am getting 101mbps download and 20 mbps upload. Show me a router that you think will speed things up a bit. I was just naming a price it can be above $200. Also after he set up the static IP and everything no one has internet now. He said that all he needs to do (he thinks) is to reset the switch and then everyone will have internet again... Im not at the office today because I am sick, so he is calling me to tell me updates.

Thanks

Resetting the switch has nothing to do with it.. Switch could give a **** what your public IP is.

What device did he put in so that you could get 101Mbit down? Did you have a docsis 3 modem before? You sure are not doing that with docsis 2, etc. He id not put some gateway device in front of your router did he? That is doing nat?

You could continue to use your wireless router as a accesspoint - but I find it unlikely that home router is going to be able to handle 100mbit throughput to be honest.

how many clients are at this location? If your going to change out your border router this kind of info is useful ;) A cisco asa 5505 with a 10 user bundle prob cost you around $400 USD.

Thats what I thought.

I have no idea. I am not at the office he is calling me to give me updates. I really have no idea how or what he is doing.

Thats why i will be purchasing the one you specified below.

We have around 12 users.

Another problem I am having is the internet connection has a lot of packet loss. When doing speedtest i get around 70 mbps download and 15mbps upload. But the packet loss is almost at 85 percent.

Thanks

packet loss of 85% would be unusable -- its amazing that a speedtest would even finish with that kind of packet loss. If you having that kind of loss no wonder the users are having issues. If you have more than 10 users you would need to by more licenses for the asa for example..

You could also look into sonicwall - prob something like a NSA 240 would run about $500 USD.

Budman I am confused on what you are telling me exactly. Are you telling me to get that type of router or switch. I am confused. Can you please elaborate. He said that the packet loss is from the router on. He checked the connection directly from the modem and the packet loss is 5-10%. So i guess my router is causing all of this BS?

If your just changing your connection to the internet I dont see why you would need to change anything at all really unless of course like BudMan said if you have got a new modem that does NATing.

I doubt your router (Inside your network) is causing all that packet loss. From my experience its not local network equipment that causes that much packet loss. I had one at home where we got lots of packet loss because of the quality of the cable from my home to the exchange. Is usually the line out if that makes sense. Get the bloke to do a test from your premise to the exchange if he can.

Are we talking about the sonicwall as a switch or a router? What would that replace? Would that lower down packetloss?

that would replace your "router". it would support your internet connection and give you much more control of your traffic.

Yeah the cisco ASA or sonicwall would replace your wrt54g2 - its highly unlikely that your switch is causing packet loss - unless you had a mismatch in your duplex level or something between your router and the switch?? And then sure the packet loss would be very very high.

I agree the sonicwall would prob be a better fit for ease of config, etc.

As to seeing 5 to 10% packet loss connected to just your modem - that too is crazy high loss and completely unacceptable - you should be seeing well below 1%, well below!!! With that much packet loss your connection is going to be crap!

Your netstat output - those are all connections inside your private network.. Your retransmits seem a bit high if you ask me - could be due to wireless connection issues??

Here just took a look at my home box

TCP Statistics for IPv4

Active Opens = 9735

Passive Opens = 19635

Failed Connection Attempts = 507

Reset Connections = 18879

Current Connections = 30

Segments Received = 10784810

Segments Sent = 5610919

Segments Retransmitted = 3172

So if you divide the sent/retrans = .00056%

yours is at .032% -- prob issues with connections to wireless???

Need to know more to know if that is something you could make better? But thats not packet loss.. Where are you getting this 5 to 10, or 85% number from? So if you ping your ISP gateway 100 times you seeing it not respond 85 times? And answers 15 times? That would be 85% packet loss.

Look on your router for its gateway IP.. then just do a simple ping -n 100, you should really see 100 replies or atleast 99 if your seeing more than that you prob have an issue.

Now my router keeps track of quality of the wan connection - as you can see over the last 2 days.

post-14624-12686762625184_thumb.jpg

And I just did a quick ping test of 100 echos

Ping statistics for 24.14.x.x:

Packets: Sent = 100, Received = 100, Lost = 0 (0% loss),

Approximate round trip times in milli-seconds:

Minimum = 6ms, Maximum = 14ms, Average = 7ms

If you seeing 5% loss you got a problem that is going to cause you issues, with 85% its not even a usable connection at all.

edit: you should be able to find the sonicwall cheaper than $1k, here for example

http://www.buy.com/prod/sonicwall-nsa-240-security-appliance-6-x-10-100base-tx-3-x-10-100/q/loc/101/210401020.html

$495 with free shipping ;)

Thanks for the help. I will try to get more information on this tomorrow when i get in the office. He said when connected his laptop to the switch he received about 1% packet loss. He told me that the line to my computer is bad. I tried all the computers on the network and they all received 70-80%, but when he connected his laptop packet loss was at 1%.. Confused.

He is like i guarantee you that the packet loss is not more than 1%. He said if you had 80% packet loss you wont even be able to open up a page. Budman whats the best way I can test this?

The bloke from the company who is installing the line then tested the line and he said that packet loss of 1%?(Between your router/edge device and the external network)Well Id say that was unacceptable if your going to be heavily utilizing your line with VOIP.

So your saying that the rest of the Packet Loss on your internal network is 70 - 80%? Like Budman Said It might be Duplex Settings? Set all the Network cards on the laptops to Auto Negotiate. Also is there anything that could interfere with the wireless signal (If your seeing it on the wireless). Remove any cordless phones or turn off any heavy machinery (just a thought) You might have to get insulated cables if your running it through a factory perhaps???

when they ask you what is causing the packet loss, pass the blame on the the rooster hanging out outside the building. and just keep walking saying you are going to get the damn rooster. they may leave you alone for a bit to figure it out, or they may call the looney bin on you. flip of a coin really, in one aspect they leave you alone in another they give you really cool meds and it won't be your problem any more.
