The term broadband commonly refers to high-speed Internet access that is always on and faster than the traditional dial-up access. Broadband includes several high-speed transmission technologies such as digital subscriber line (DSL), cable, fiber optics, wireless (for which there is a separate topic), satellite and broadband over powerlines (BPL).

With my Tenvis camera connected to my home's Wifi SSID and my laptop
connected to my home's Wifi, I could http://Tenvis_IP:7777  & see what
the camera sees.

However, at my company, I can't connect my Tenvis camera to the Guest
Wifi as it requires registration plus clicking a couple buttons on the
landing page before the device could connect to Guest network.

Now, I'm replacing the Tenvis with my iPhone using the steps below:

However, with both my iPhone & laptop assigned an IP each by Guest Wifi, my
laptop still can't ping the iPhone & can't see the videos despite that both iPhone
& laptop have registered successfully & clicked the necessary buttons to get
authenticated/connected to Guest.  How can I overcome this?

I plan to put the iPhone in my car to monitor the car (using the laptop) as my car
is parked within the vicinity of the company.  I could sign up a data plan for the
iPhone but it's going to cost quite a bit to monitor 22 days, ten hrs per day so
tagging onto the free Guest Wifi.

I have one public IP on my broadband router and three servers with private IPs. I have configured port forwarding (3389) for one server. It is working fine and accessable via remote desktop connection.
Now I want to access all servers remotly (via remote desktop). How I can configur the port forwarding (3389) for all servers.
Dear Experts

We have a network of less than 15 systems with 2 broadband connections from 2 different ISP's.
1. ISP1 in their provided router configured the network of and their provided router ip and function's as DHCP server in the LAN
2.. similarly ISP 2 also configured in their provided router with network of and their provided router ip and this also funcationing as DHCP server in the LAN.2
Both the routers of both ISP's are connected to the same switch at the present I have turned off ISP 2 router to avoid 2 DHCP in the LAN.
3. have linux server working as internal private DNS
As per the experts exchange experts advice I am in process of procuring the router with 2WAN port so that each one of the ISP will be connected to one of the WAN port and will stop DHCP service on the router level and will configure DHCP server in linux server. I would like to divide the network of to 4 subnets, as following
a)  of ip range 1 to 62
b) of ip range 65 to 126
c) of ip range 128 to 190
d) of ip range from 193 to 254

attached DHCP configuration, request to please review the defined 2 subnets statements in the config
Soution design and suggestion for the below please:
in this dhcp server the defined 2 subnets i,e access point-1 to one of the subnet of above a) i,e  of ip range 1 to 62 and access point-2 to another …
What technique old modem were used. PAT or NAT? and Now a days which technique broadband routers are used?
We have purchased a Netgear Nighthawk X10 ad700 model R900 router and we are unable to use it.
The issue is when we configure the router, they are getting connected but then they are automatically getting reset within an hour. we are not able to configure again for the day.
Can someone help us to sort out this issue?
So i have a Standard home broadband Netgear router (DGND3700v2) it connects  to ADSL using a phone line.

can I use a RJ11 TO RJ45 converter and then plug that phone line straight into the outside ethernet port of an ASA5506 and then configure the port to use PPPoe with the credentials from my ISP? would that work?

Would it be a lot of data loss from SM to MM?
We have fiber from ISP [10Gb] is 9/125 SM going from SC to LC then into our LC 50/125 MM then into SM switch network module with SFP.

Would I have a lot of issues with that setup?

 I also read some people are using mode conditioning cables.  Will that help a lot?
My company use T1's extensively through CenturyLink and 1 location is operating on 6 miles of very poorly maintained copper pairs. While I understand the provisioned rate to be 1.544 I was wondering if there is such a thing as a minimum guaranteed speed as we are only able to get 1.2 out of the circuit. There are multiple interferers in the count and poorly or missing bonds/grounds. It's similar to trying to run a formula race car on a dirt road.
I have SonicWALL Firewall/Router and 5 public IP address. I am going to have 1G Fios connection soon; however, the my soniwall won't give the 1G connection speed due to the DPI.
I would like to create second network that outside of firewall and wondering if I can split by public IP address with separate router.  Do you have any solution for this?
I have a 20/100 internet connection. Im mirroring a couple NAS in a remote location, but its hogging my entire network connection. How do I limit that incoming connection to use only about half my bandwidth? Can this be done with ddwrt? Netgear etc? Im using Synology NAS and I know the particular port that is being used is 9960. I would image there was a way to say everything coming in on port 9960 has a quota of 50mps or something like that.

I always get confused / use firewall / router rules so infrequently that I don't know  what the right way to set these things up.

Can you help?

I have a VOIP service using a Grandstream HT-502 V1.2A gadget.  The call quality isn't always good.  That device is plugged directly into one of the ports on an actiontec router (left over from when we had verizon fios, but now we have cable internet 15down / 5 up speed.

I have lots of other devices plugged into a gig network switch in the basement that might be using the internet at the same time as the calls?  That gig network switch has 1 cable going over to the actiontec also (so there's only 2 cables on the lan side of the router).

To improve call quality, that's a job for QoS, right?

The attached picture is what I did in the actiontec router.  The grandstream has the ip of

But then i thought, should this be on the Ethernet/Coax or  Broadband Connection (Ethernet/Coax) sections? Did I at least get outbound rather than inbound correct?

But that just gets the call out of the house with highest priority.  Once it's on the web, it's fighting with all kinds of data / can't prioritize it, right?

Does the VOIP provider have any bearing on the quality of the calls? Iwe are using  is there  a way to substantiate / test where the poor qiuality - dropped fractions of a second in the conversation, etc.  NO stuttering, max headroom type things.  Just a m ssing sound here and there.

Hi Experts,

We mainly offer workstation and server support in the UK. The client here has broadband with another supplier, and we supplied the router only. However, now we have been asked a comprehensive questionnaire for PCI compliance (Credit card payments). We are wondering how to respond because it’s fairly involved. Any advice please?

Is there a current network diagram that documents all connections between the cardholder data environment and other networks, including any wireless networks?

Is there a process to ensure the diagram is kept current?

Is a firewall required and implemented at each Internet connection and between any demilitarized zone (DMZ) and the internal network zone?

Is the current network diagram consistent with the firewall configuration standards?

Do firewall and router configuration standards include a documented list of services, protocols, and ports, including business justification and approval for each?

Are all insecure services, protocols, and ports identified, and are security features documented and implemented for each identified service?

Is inbound and outbound traffic restricted to that which is necessary for the cardholder data environment?

Is all other inbound and outbound traffic specifically denied (for example by using an explicit "deny all" or an implicit deny after allow statement)?

Are perimeter firewalls installed between all wireless networks and the cardholder data environment, and are these …

Do cable broadband "splitters" work ?

Problem: one cable going into "TV Box" but if I remove this and use a "splitter". Does this mean I connect it to a cable modem?

We have a newly installed Eircom router.

Our broadband is coming in through a cable coming from Eir, our national broadband provider, to the Eircom router.

- There has been a constant internet connection problem with the Eircom router for months, before and after the new Eircom router has been installed.

- The problem has been most noticeable on WiFi connected devices where WiFi internet connection would be lost for about 1 - 2 minutes every 15 minutes or so, can be random times sometimes, e.g. could be watching YouTube on laptop which uses WiFi and video could stop loading for 1 minute, would display internet disconnected at bottom right corner

- We have everything disconnected from the Eircom router.

- We have reset the Eircom router many times to try and fix the internet problem

- There was an Aruba IAP-305(RW) connected to the Eircom router which provides the WiFi as we disabled WiFi on Eircom router

- We have the Aruba IAP-305(RW) disconnected from Eircom router as we want to limit the test to just the Eircom router and broadband.

- I have heard that basic ping tests are not very helpful for testing performance.

- Ideally a 12 hour test may be better to test internet connection

We would like to know how to truly test all the parameters of the Eir broadband.

What would be the best way to test these parameters?  

My cable provider just sent me a new cable modem to keep up with Docsys 3.1 standard.  It is a Samsung GX-MC990CL.  The interface my cable provider gives to configure it is not the one that is built in to it.  It is truly pitiful.

I would like to access the GUI that is built-in to this modem.

Does anyone know how?

No matter what router I use, I only get 30 - 50% of the internet speed through it.

If I connect a laptop directly to the Comcast modem, which is in "Bridge mode" so that the connected device gets a public IP address via DHCP, I get about 100mbps.  If I connect a router BETWEEN the modem and the laptop, the speed falls to 30-50.  There is NO OTHER device connected to the router or the modem.  I have confirmed this problem using a SonicWall TZ400, a Cisco RV180, an ASUS RT-N12, and a UTT ER518.  The issue remains for each of those routers.  I also used the same patch cables for each measurement.  Wireless is not involved.  

Why does this happen and how do I change it?

This is an addendum to an old ticket which can be seen here:

The problem described in the old ticket is still occurring. Random devices will pull a 192.168.0.X address. I put in a new Unifi network (With a new Sonicwall) but the exact same thing is happening. The DNS server changes as well. The DNS server on the firewall is listed as, which is exactly what devices that pick up the CORRECT 192.168.1.X subnet read. However, those that get the wrong 192.168.0.X subnet read the DNS server as, which is the old TW/Spectrum DNS. I have no idea how it's grabbing this.

This "wrong subnet" problem only appears to occur with the wireless devices, as no hardwired device has shown this error so far. That leads me to believe it's either a setting in the Unifi setup (For which I've kept all of the defaults) or the way the Unifi is talking to the Sonicwall. To combat this problem with laptops I've gone in and set static IP addresses from the PC side, which seems to have corrected the problem.  However, with the Nest devices, this isn't an option, as there is no way to manually enter network info.

Instead, I created a  static IP for the Nest devices on the firewall. If I reboot the devices they SOMETIMES pick up on the correct subnet, and when they do, it's the static IP I gave them in the firewall. However, after a few days of working properly they …
Are other ISPs besides Comcast able to use Comcast's DNS server addresses of &

An organization I am working for has switched over to using Comcast fiber optics as its primary internet service provider (ISP). We also have a second internet service provider (Etheric Networks ( which provides satellite dish based internet services.

Our internet service is set up in a failover configuration using a SonicWALL TZ600 router so that if our primary Comcast fiber optic internet service fails then our internet service will automatically switch over to Etheric until the Comast fiber optic service is restored.

We would like to continue to use the static external DNS server addresses of and in place if our internet service ever switches over to Etheric should the Comcast fiber optic internet service become unavailable.

Our question is if our internet service switches over to using the Etheric internet service will the external IP DNS server addresses of and still be valid and provide timely DNS name resolution?

Or is there a different type of method we should be using to handle our internet service and DNS name resolution switch over?
