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 192.168.1.0/24 and their provided router ip 192.168.1.17 and function's as DHCP server in the LAN
2.. similarly ISP 2 also configured in their provided router with network of 192.168.1.0/24 and their provided router ip 192.168.1.1 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 192.168.1.0/24 to 4 subnets, as following
a)192.168.1.0  of ip range 1 to 62
b)192.168.1.64 of ip range 65 to 126
c)192.168.1.128 of ip range 128 to 190
d) 192.168.1.192 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 192.168.1.0  of ip range 1 to 62 and access point-2 to another …

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?

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?

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?

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 …

My customer's building has about 30 tenants, each with broadband and a router. Is there a way, hardware or software, to reboot all the routers automatically ? Perhaps on a monthly basis.

Hi,

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?  

Thanks,
Robbie

hii I have a 10meg line and when I play online my ping wil start normal on about 250ping but after a wile my ping wil jump to 999 for about 10 seconds and back to normal sometimes longer how can I fix what can I do.

Are other ISPs besides Comcast able to use Comcast's DNS server addresses of 75.75.75.75 & 75.75.76.76?

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 (https://ethericnetworks.com/) 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 75.75.75.75 and 75.75.76.76 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 75.75.75.75 and 75.75.76.76 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?

for Dual band Routers... can I use the same SSID name for my 2.4 and 5ghz. I already know the answer to the question but I am getting a second opinion for someone .

Protecting myself on someone else's WiFi

I do carry a MiFi for mobile broadband, but may find myself in a position to use a wireless network at someone's house whom I have just met.

How can I best protect myself in this case?

What are the risks, even if I follow the best practices you lay out for me?

Thanks
