i cannot access the web managemnet interface of this router from a different subnet.THe WAN interface is a 4G LTE connection,I have disabled both the SPI firewall and NAT and enabled remote management from any ip address but i cannot access the admin web page from a remote subnet.Doing a port scan of the routers WAN or LAN address i cannot see any ports open at all...its as if firewall or NAT is still enabled somehow.

I have seen that when ever i am using the packet data connection (GPRS/EDGE) on mobile and if a Voice Call comes, the Package data will be stopped and once the call gets disconnected it will resume sending the data.For 3G Data the same is not happening, at the time of voice call it will continue sending the Packet data.

We've come across an issue whereby the WAN port fails to light up with an Adtran Total Access 832 (via bonded SHDSL) unit.
Eventually the WAN port does light up after connecting and disconnecting it several times with the ethernet cable. However as a test I power cycled the router with the WAN cable disconnected and had a strange issue where the WAN light would constantly flash and show up in the web gui as being connected when in fact the Adtran Unit showed the device was not connected at all.
This is the second Cisco SRP521W router in place as the original one disconnects overnight without any load and a power cycle would fix the issue, but this replacement router disconnects during business hours (even worse for the customer) and power cycling does not bring it back online. We've adjusted the WAN port to 10MB Full on both devices and hope that it stays up. I am wondering if any has had a similar experience? Would this be a behaviour of a faulty unit or may it not be compatible with the Adtran Total Access 832 (via bonded SHDSL) unit perhaps?

I have a problem in connecting SRP521w with CCA v3.2. I tried to connect the device with CCA but it said that that the device is unsupported. I already upgraded the router's firmware with v1.01.26.
Here is what the CCA looks like every time I try to connect with the router :

Is it possible to send all traffic through site to site VPN using SRP521W (on the other site ASA) ? Lets say, traffic to Internet from branch through HQ - site to site VPN between branch and HQ. I've tried to set up destination crypto policy entry to 0.0.0.0 0.0.0.0 but it's not accepted. Firmware version is 1.01.26 (003)

Have followed the admin guide, and can setup this up fine, however what we're wanting is to turn off any IP connection for the main wan ethernet interface and only have the sub-interface have an IP connection method.
I can't see how you can turn this off, which is causing a double-up of dhcp requests being sent when using both the main/sub ethernet interfaces to use dhcp.
This has been tested on the 521w and 521w-u versions, and I've just used the latest firmware 1.2.4 on the u version.
How can this be configured so that there is only 1 WAN interface that is using IP (the sub interface) Setting default routes to point to the sub interface doesn't make a difference.

Any recommendation for creating a configuration template for the SRP521W? I can use the Admin-->Backup Config to get a xxx.cfg file, but I cannot edit it with notepad++. Also, i know the config can be view via view-source: [URL], but how would I load a modified copy of this back to the router?

I am trying to create a VPN between a SRP521W (only point-to-point VPN) and a UC560 (VPN server) and it seems it doesn't works (SRP doesn't create the tunnel).

We have been using a SRP521W as the main Router for an office with about 25 users.
So on the cable network it's about 25 computers, 25 IP Phones, 3 printers. Wireless network hold some smartphones and tablets. Computer traffic is 100% Remote Desktop.
That said, for the last few days network connectivity sucks. I think the problem is, precisely, the SRP521W. Some mornings the WAN link is down and can only be brought up by a router reboot.
There's an IPSec tunnel to HQ.
Wireless network was moved recently to a WAP121 to offload the SRP521W. It has two networks: internal and customers with two VLANs.
CPU Usage is around 30-45% all day and spikes to 100% sometimes. RAM Usage is 40-45%. I do not know if this is "too much", "average" or "really low load".
Anyway, time for questions:
a) How can I get a table of active connections on the firewall/NAT to see if there anything "strange" on the network traffic that maybe causing issues?
b) Is there any know bug in the VLAN handling of the SRP that maybe causing the issue? (it's one of the latests changes introduced).
c) If the problem is that there's too much load for such a small router, what replacement would you recommend given the details above? (remember I do not really need wireless on the router as I have the wap121).

Just brought another set of SRP521W, after changed the WAN setting to PPPOE, we unable to access the web management. The power/sys light will keep blink when trying to access the web management. We able to ping it. We tried the reset button but it did not work as well. Is that a way to upgrade the firmware without using the web management?

The setup:
Time Warner Cable Internet Dynamic IP
DIR-655 A3 Firmware 1.21
3 hard wired, fully updated, virus free, windows xp pro machines
The Issue:When only one PC is running or actively being used there is no issue. However, when there is moderate internet usage on a second pc the internet connection will drop (the WAN light on the router stays on as does the ethernet light on the modem) and give this pair of log entries.

These are the IKE policies: Here the IPsec Policies: and the GRE policies:

I'm planning to set up a network with two routers and one cable connection. One router will be for public wifi at my business and the other will be for my Point of sale system and private use. I think I have it figured out but want to double check the set up. Someone tell me if this isn't correct or if there's a better way of doing it.Cable modem --> connect via ethernet to Router #1 WAN port. Router #1 Lan port 1: connect via ethernet to router #2 WAN. Now, router 1 and 2 will have two different subnets; 192.168.1.x and 192.168.2.x respectively. Router #2 is the one that I should use for my private network and for the POS system since it can't be accessed by users from router #1 correct? I have DD-WRT installed on both routers but I plan on putting Tomato firmware for router #1 to limit bandwidth for public wifi and keep DD-WRT installed for router #2.

i just setup an RV220W as my home router. Everything connected fine, etc. however, one of my wireless devices (it's a security camera) disconnects after 1 hour. I am able to reconnect the device if I either reboot it, reboot the RV220, or disable / re-enable the Port Forwarding rule I've established for it. Other wireless and wired devices do not have any issues. In the past, I had this same camera working for over two years over wireless while it was connected to a Linksys E2000 router. I enabled the logs on the RV220W last night, and the error message that I receive is: secureBit not set in GTK Msg2. I've got the same SSID on the RV220 that I had on the E2000, same port forwarding, same MAC address client list, etc. Like I said, none of my other wireless or wired devices disconnect at all, just this camera, which worked flawlessly until I switched routers.

Having problems with my wife's laptop. It is connected to our wireless home network - but every so often (and it seems to be happening with increasing frequency), the connection breaks right in the middle of whatever she is doing. The laptop has to be restarted in order to reestablish the internet connection.
This problem has happened at other people's houses when we were connected to their wireless - so the issue appears to be with the laptop and not with the setup of our wireless network.

We recently switched from a ADSL2+ service to a 2Mb SHDSL link. Uploading images to our website is happening all day long, thus greater upstream bandwidth was required.
Our downloads are suffering somewhat, the upstream gets easily flooded and downloads start to trickle.
I have a SRP521W which has a few QoS options. The QoS Bandwidth control has upstream bandwidth set to 2048 Kbps. Now I don't know how to enforce anything. How to use the WAN strict high priority queue appriopirately.
The website has a static IP address, so I can target that in the rules to only use 80% of the bandwidth?Alternatively can I limit upstream traffic per user?

On my Switch (3750), i have a host connected. Checked the interface status and it shows as "connected". However, when i tried checking the MAC connected to that interface, its not showingI have my Switch (3750) connected to a Router (3845). On the Switch, i have a printer connected in an interface. I am seeing the Printer's MAC associated with the switch port. However, when i checked the ARP table; no entry seen for the Printer's MAC. What are the possible reasons for this? We have several same kind of devices connected to network and they are fine.

I bought a WAG160N ADSL2+, I configured it and all the computers can connect to it with wireless. But the problem is sometimes the connection between the wireless adapter and the router will disconnect and I'm not able to connect again (the computer screen in de bottom right corner has a red cross in front of it if you know what I mean). It can take hours before it will be able to connect again. The only way to have the connection back up is to turn off/on the WAG160N. This happens mostly on my machine (windows XP Dlink Dwa-131 adapter and with the adapter that came with the WAG160N) and afterwards on the other machines. Its like the router doesn't want me to connect anymore.

I've configured a lot vpn server for 857/1800, etc. But this has never happened.I configured 881 as VPN server using CP.Shared key, local group and local user authetication with split route.Local pool 192.168.100.1-254? I have acl for telnet which allows local pool IPs.I have acl to deny local network to local pool IPs for NAT.I've deleted the whole settings and re-run the wizard. It's still the same thing. I can connect from the VPN Client, but no traffic going through. The problem to me is isakmp with DPD. But why it is dead? Why no response from the server? If it is an error, why connection has no problem.

When I connected to the Internet by using WiFi, my laptop will suddenly disconnected. Sometimes it works to fix it with troubleshooter but sometimes I have to restart my laptop again and again. The troubleshooter mentioned it can be driver/network adapter problem but how to stop DC. I sent my laptop to the service center, they said this is not about my network adapter problem and asked me to reformat my laptop and check whether this issue can be solved or not.
