A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

When ipconfig/renew, it doesn't change the private IP, stays the same.  We have tried "/release" then "/flushdns" then "/renew" to no avail.  We also turned off the modem router and turned it back on, still same IP.  We read somewhere that in order to any router assign a new IP, both computer and router has to be off at least an hour (that didn't make sense).
So we turn to EE; please advice on the proper way to have the computer automatically be assign a new IP to a computer (the computer is windows 10 pro).

Last night in a meeting we were informed that wp2 is no longer secure that a new method for   vracking WPA/WPA2 Passwords on 802.11 networks has been recently discovered.  

Any EE aware of this? How can we protect our WiFi routers against this new threat?

This "equipment room" is in a area that is not easily accessible. What I am finding is that if a "normal" battery backup is completely drained it will not turn back on automatically when the power is restored. There will be no computers on this battery backup. Just switches and routers. So I am looking for a battery back that will automatically come back on when the power is restored and in turn bring the switched and routers back up so no one will have to get to this room after a power outage and manually turn the battery backup back on.

We are looking for a LTE Modem/Router like the Cradlepoint.  We have been using the MBR1200B Cradlepoint, that has been discontinued.  The MBR1200B was in our price point.  We use this for onsite construction trailers on construction sites.  No WAN/ISP is available.  We need Ethernet connects also that is why a Verizon/ATT/TMoblie MiFi’s don’t work for us.
Verizon is preferred if possible.  Looks like Netgear has something similar.  Looking for real reviews or ideas on other products like Cradlepoint.

I am helping a friend who has young teenagers and who wants to restrict their Internet access to sociable hours so they don't sit in bed all night talking to their friends on Facebook etc.
We have a BT Router and a Ubiquiti access point.
The first plan was to use disable the wifi in the BT Router and set a schedule in the Ubiquiti - this worked well but for a short time until they discovered that a factory reset of the BT Router gave them back the 24x7 access they wanted.
With hindsight it would have been better if we'd removed the access codes written on the back of the router and kept those secure then even if they performed a factory reset they still wouldn't be able to log into the wifi. Too late now because I'm sure they've made a note of the BT codes.
Most other routers I can think of have a default username and password so it wouldn't take a teenager many minutes to look up the username and password ready for the next factory reset.
What is really needed is a Internet Provider control panel at which you can set access codes, wifi schedule etc.
How do others get round this or is my friend alone in trying to protect his children from Internet over-use?

We use 2 ISP's to provide internet connectivity and failover to a router. I am trying to clean up and get a clear understanding prior to an ISP change. At some point in the past a former consultant configured policy based routing to help balance the load between ISP connections, this is no longer needed - all we need is for the primary connection to fail over should a failure occur, and for the route to return when it come back.

Questions;
1) Are the route-map entries (and corresponding ACL's) required for failover or is this managed via SLA?
2) The SLA echo IP's appear to be those of the ISP DNS servers - would we be better off using something father upstream and past the ISP? We had an issue lately where the ISP failed but the router did not failover to the backup connection (failover has been tested and is good)
3) I am confused with the ACL entry applied to route-map PBR as following. The ip host in question needs (and has) access out through the router - can anyone shed light on what this DENY statement is achieving?
access-list 102 deny   ip host x.x.79.120 any

Pertinent config entries follow.

track 1 ip sla 1 reachability
 delay down 180 up 180
!
track 2 ip sla 2 reachability
 delay down 180 up 180

ip sla auto discovery
ip sla 1
 icmp-echo x.x.87.24 source-interface GigabitEthernet0/1
 frequency 5
ip sla schedule 1 life forever start-time now
ip sla 2
 icmp-echo Y.Y.41.10 source-interface GigabitEthernet0/2
 frequency 5

We assign a static ip address 10.10.10.10 to a server which is connected to switch. the address are not in exclude range of dhcp. If the server is turned off, the ip  10.10.10.10 would be assigned to other user? if so, i think when the server is back on line, this would cause duplicate ip issue, am i right?

What is the process for logging onto a Cisco Catalyst 3560 switch?

This is a Cisco Catalyst 3560 Series 48-Port PoE Ethernet Switch WS-C3560-48PS-S V04.

This switch is running iOS version 12.2.(25).SEB4.

Does this have to be done using a utility like Hyperterminal or can this be done with a web browser?

Spectrum on behalf of Sony sent a client this e-mail: {Removed IP address below}

To whom it may concern,

Pursuant to Sony Interactive Entertainment LLC ("SIE") corporate policy, the below IP addresses were blacklisted from using our services because SIE detected activity that is abusive to our network services. In our determination, the abusive activity was not related to velocity or volume (many users behind the same IP address, i.e. NAT), but matched the specific patterns of known abuse of our publicly available services. This abuse may be the result of a computer on your network that has been compromised and is participating in a botnet abuse of our services.

The following table of IP addresses, dates and times should help you correlate the origin of the abusive activity.  The time stamps are approximate from our logs.  The actual timing of the events depend on the signature matched.  It is very likely to have occurred both before, during and following the times listed.

       Approximate Time Range (UTC),      IP Address, Reason
2018-07-23 12:46:00 ~ 2018-07-23 13:46:00 (UTC),   xxx.xxx.xxx.xxx, Account Takeover Attempts

It is most likely the attack traffic is directed at one of the following endpoints:

account.sonyentertainmentnetwork.com
auth.api.sonyentertainmentnetwork.com

These endpoints on our network are resolved by Geo DNS, so the IP addresses they resolve to will depend on the originating IP address.

The destination port will be TCP …

How do I add a port forwarding rule to Mikrotik HEX s router?  I need to forward any traffic that comes in on 443 to a node on the LAN 192.168.88.100.

I found the following in the manual: /ip firewall nat add chain=dstnat dst-port=443 action=dst-nat protocol=tcp to-address=192.168.88.100 to-port=443.  I opeened a "New Terminal" session and try to paste that command in without success.  I also tried to issue "IP", then "firewall", then "nat", then "add".  This is my first time working with a Mikrotik and I can't get the command / syntax correct.

All,

We have a single domain *.Domain.com, this domain is hosted/registered with Goddard. We have only one ISP at the moment to route the traffic(email and web) to internal hosts(local network). We have plan to have to use two ISPs at the same time for fail-over in case we lose connection with ISP1 the second ISP will take care of internet incoming/outgoing traffics.
My question is:
Can we use two ISPs at the same time for MX and web traffic?
Can we make two entries for MX on godaddy DNS?

Regards

Hi All,

We have MPLS network between the Head Office and Spoke site. There is no internet access over the MPLS. Our current services are not reliant on the internet so current setup works fine. We do not have any access to the current MPLS routers at the head office or at the Spoke site and we won't be able to change the configs in any way.

We are exploring a new software setup at the Spoke site but it will require internet access. This software runs on Windows 10 normal PC but needs internet to connect to its own Cloud for emails & dashboard reports etc. It does not work over "Proxy" for some reason.

At the Head Office, we have internet but not currently linked with MPLS. We can put a new router (Router 2, as per diagram) that can allow internet access.

The Win 10 PC can ping the router-2 IP (10.10.1.4) & we have tried to key in the static route: "route -s add 0.0.0.0 MASK 0.0.0.0 10.10.1.4 but still, the internet does not work.

Tracert shows the requests are getting dropped at the next hop. For Ex: "tracert 4.2.2.2" will not even each the Head Office network. Is there something else we can try?

Regards,
Kuldeep Saxena

iPad mini (Not sure what version) with new Canon MF236n printer on network.  Canon Buisness print was installed and test print jobs were done successfully.  The printer is brand new, installed yesterday.  Today the client called and said AirPrint results in NO PRINTERS FOUND.  He has attempted several times, and standing near the wireless router even.  I have used the older MF216n with apple devices for years without issue.  In fact this job, I replaced a power failure MF216n device.  What steps should I recommend to end user for troubleshooting?  The printer is working perfectly from all Windows devices (including wireless).

Hi Experts,

This week I got a Panasonic ToughBook CF-33 and switched my ISP from Bell to Rogers.

Over Ethernet, using speed-test.net, download with Bell was 300Mbps, with Rogers is 500Mbps.

Over WiFi, the ToughBoook was 80Mbps and now <20Mbps.  On my iPhone, Rogers is getting 300Mbps.

Why is my ToughBook now  under 20Mbps?

One thing that I noticed now is that with Rogers my router is now Hitron CODA-4582U, and the SSID for 2.4GHz and 5GHz can't be the same, where on  Bell (Cisco) they were. The ToughBook now cannot detect the 5GHz SSID. Does the ToughBook CF-33 not support 5GHz?

To make matters even more interesting, my printer only has WiFi interface, which makes it on a different network because of the mismatched SSIDs

As I am typing this I am wondering should I purchase another Cisco router and make the Hitron only as modem?

Any help will be appreciated.

Hi We need to add a few of APs(3500) to WLC.(5508). I wonder if we need to configure channel number manually in order to avoid Co-Channel Interference? or we just add these APs and then APs can automatically be assigned some best channel ? Thank  you

Peplink Balance One router/ap unit reporting latency issues with wired/hard wired network devices.  need to perform direct to the cable modem first but I like to have access and documentation later for if and when I have to troubleshoot this unit.   The site seems to be lacking a manual nor is as easy as reaching the gateway IP to access the GUI.

Anyone familiar with access to this unit?  Does anyone spot the manual?  I sent a troubleshooting ticket a month ago to Peplink and they have yet to respond.  They don't even have one phone number on their site anywhere.

I'm trying to setup another SSID on a Cisco 2504 WLC. I've mirrored (I believe) the settings of an already existing SSID/network with the difference of subnet, etc. The traffic is routed through a Cisco 2811 and various switches. The switch that identifies the VLANs, has also been configured accordingly. Could be problems in multiple places since I've done this a number of times, but never came across this issue.

To start, I can't ping the interface IP of that newly created SSID from any device, including the switch that the controller is connected to.



This is the config of the switch that the controller is connected to where the other networks work:

I figure if I can get to the interface IP (as usual), I'll be able to get to my DHCP server, get an address, and get to the internet.

Any assistance is greatly appreciated.

I work for a school district and have three buildings each with roughly 300 computers.  We have two buildings in one network (ip scope) and the third in its own network.  We are thinking about closing the one school building and moving the 300 computers and users to the other campus of two building.  I am concerned about having so many devices on one broadcast domain.  Would one network with 1,000 devices be a bad idea in terms of traffic?
