I am not a network specialist, but I would throw out two things to look at. You seem to be using POE devices. I've seen something similar happen at a hospital and it was due to the two areas not sharing a common ground. The ground was described as "floating" and zero voltage at one side of the campus was higher than the other. Power as a result flowed ...

I would first recommend isolating which side of the access is truly dropping (or both). Clients (and by clients I mean your servers, desktops/laptops, etc.) should be able to connect to your internal network and the router, even if you are unable to access the internet. If this is the case then you have at least isolated the issue is between the router and ...

I have the same problem using my Buffalo N600. No idea why, after months of no trouble, I can't connect. I've power-cycled the whole network. I have no trouble seeing other machines on the network but can't get to Internet. I tried renewing DHCP leases and connecting from other machines. I can't get past the router. When plugged directly into modem, I can ...

The best way to do this is to remove it from the network and connect directly to it with a spare network cable. You should then be able to configure it via your web browser using the default router IP address (192.168.0.1). Once you have it set up how you want it, e.g Security, SSID, you can then reconnect it to your network.

Some great answers here, but others that just don't understand the technology. Let me answer with a fictitious, non-technical example. Let's imagine a world where the "highways" are 11 "lanes" wide and the vehicles are 5 lanes wide. Driving part way on the "shoulder" is allowed. If there is a vehicle going slowly centered on lane 3, this would cause ...

Looking at the broadcast range on this site, it appears that if you are more than 20 feet from the router, the speed decreases drastically. If the distance is far enough, the 802.11ac would be slower than the 802.11n since the 5GHz frequency (for 802.11ac) has a shorter range than the 2.4GHz frequency (for 802.11n). So no matter which band your wireless ...

Disabling DHCP service on the Wi-Fi home gateway is part of the solution, but not the whole thing. To make it just a transparent bridge between wireless and wired, you also need to disable NAT. Some home gateways don't let you disable NAT, in which case you should just disable DHCP service and then plug the gateway's LAN port into the upstream switch. Home ...

The proof of the pudding is in the eating! 1-6-11 is often worse in moderately congested areas The 1-6-11 recommendation contained in Cisco's whitepaper about IEEE 802.11 deployment in the corporate environment certainly does not apply to all circumstances! For example, in moderately congested neighbourhoods, one stands a very good chance to benefit from ...

Yes you are correct. If you disable DHCP on the end router it will become a Access Point/switch. As you said assign a IP to access it through webpage.

The problem was within the Ethernet card settings of the PC. It had multiple separate options for waking up by a magic packet. One was not enabled. So make always sure you have enabled Wake-On-LAN in BIOS, Network card settings and OS settings and it should work.

Set up front (Verizon) router a NAT and DHCP device, put others behind it setting it to swtch/AP role (= no NAT on it) - that's it. Or you'll end up with pretty messy scheme which you may not want to maintain. As an alternative, consider set up Verizon router as a bridge (which will efectively disable wifi on it), then use Cisco as NAT device and put 3rd ...

Although I haven't been able to recreate my situation in a while, I have found what I think is a fix. ( If it isn't I'll fix my answer ) Trying to recreate the situation I accidentally disabled the network driver and had to find it and enable it. This driver seems to be responsible for connecting to routers so I could disable it whenever it acts up. All ...

I have no experience in this matter but my first thought is that when you detect that the internet connection is down, redirect DNS requests to a DNS server that maps all requests to a web server that says "the internet is temporarily down" (e.g. set up your own DNS server and have your DHCP server deliver that, possibly forcing renewal of all leases during ...

I am not even sure if this is within the scope of Super User. However if I try to address the actual problem then what you want to achieve is called jamming the signal. You don't use high tech hardware that transmits valid signal on the same channel in order to jam someone else's signal. This is both not cost-efficient and not effective. If you really want ...

From your last comment I take it you try to build a WLAN network. With the right equipment (which you should have if you have 2000 users) this would still be only one network. Maybe you would be best served, if you try to build this in a simulated environment with http://www.gns3.net/ or the https://www.netacad.com/web/about-us/cisco-packet-tracer Anyhow, ...

Since both your AP and your card support both bands, you are free to select whichever one you want. However, you cannot connect both bands simultaneously. WiFi just doesn't work that way. If you configured the SSID for both the 2.4GHz and 5GHz bands to have the same name, your laptop would only see one SSID, and you would only have one entry to connect ...


1

Just to be clear, that card can use either band, but it can't use both at the same time. That is, it's not "simultaneous dual-band" which is also called "dual-band concurrent". I'm not aware of any client card that is. Simultaneous dual-band support is something only APs do, in order to support legacy 2.4GHz clients and more modern 5GHz clients at the same ...

You need to use Command Prompt Then do ipconfig /dnsflush, this will delete all of the cashe that is causing the internet to slow down a bit. Also you need to reset your router at least once a month and update it reguarly. Install the driver as it'll fasten a bit. Then make the IP 208.67.222.222 and then the ALT should be 208.67.220.200 to fasten up ...

DD-wrt also has a watchdog feature that looks like it would do exactly as you want.

first off your terminology was not too bad so not to worry :)... In my opinion you are correct that the router is working as a switch. You normally have four 'switch' ports on a router and an internet port which can be either for a phone line, Ethernet cable or coaxial cable depending on the router. Now what I believe is happening is that your DHCP ...

It should be possible to do it, but I can only test it with a one-card DD-WRT router because that's all I have. After your router has booted, its hostapd.conf file is visible in /tmp/ath0_hostapd.conf for my one-NIC router. You can check your two-NIC situation by means of ps | grep hostapd which, in my case, returns ps | grep hostapd 730 ...

Nope. At least on a TP-LINK TL-WDR4300, the network mode is assigned per radio, not per virtual interface. Your best bet would be to either abandon the wireless part (run a cable) or get a cheap dedicated access point - and place it on a different channel. Click for full sizeClick for full size

You first need to access the router settings by going to: http://192.168.1.1/ If you can't access, you need to change your network settings. Huawei's default username is user and default password is also user. Then, in the settings, you need to go to: Basic (in the sidebar) WLAN (below) WLAN Filtering (this is a tab) Click in enable and wait a ...

Have you looked into BitTorrent Sync? It seems to be your best fit. You both install. One of you creates a new share folder, generate a key. The other creates a new share folder, uses the key from the first user. Files are now automagically synced. There's some decent code in it for getting through firewalls and NATs and such. Upside, no router craziness, ...

You should be able to do this by signing into your router admin page, going to advanced > Filter and drop int he mac address as well as the start and end times/days for the filter. If you block the mac 7 days a week from 00:01 to 23:59 - it should accomplish what you want.

Sounds like an issue with either the SSID broadcasting, or the channel. Set the "SSID Broadcasting" to 'Disable', apply the settings and then change it back to "Enable". Also enable the "Auto Channel Scan". This will tell the router to look for an empty channel to use for WIFI instead. There could be a lot of interference on the default channel 6. ...

Is it possible that your internal ip address got renewed from the dhcp server on your router to a new ip causing any port forwarding you've done to point to the wrong ip address in your internal network and also causing the domain from noip to point to your static ip but not the correct ip on your internal network? Sounds highly probable that that is the ...

I assume that your static IP is IPv4, but I see that you have IPv6 on, which may cause a confusion. Try to turn IPv4 off in the PC and the router. As far as the PC is concerned, here are some useful resources. How To Disable IPv6 On Windows 7 (article 1) In Control Panel -> Network and Sharing Center, click the connection, then Properties, uncheck ...

A couple of things: Resetting to factory defaults is the simplest way to do this, and is what you're going to want to do. However, before doing that: There are many methods a router can use to connect to the modem and get service from the ISP. The risk you run by resetting it to defaults is that if the default settings are not appropriate, then you won't ...

Presuming that it's your own router and the password was set on your own computer, then the password is sitting right there on your computer waiting for you to find it.

Not sure how much data you are sharing but you could consider DropBox. Then you can just sync a folder on your local filesystems; and anything you put in that folder will show up on your friend's machine. The free service gives you 2GB of storage. The $10/mo service (which I have and love) gives you 100GB. Another option is a VPN, one of you can get a VPN ...

My suggestion would be to start a FTP server of the files that you wish to share and share them over the internet, as far as I know, without dual radios/SSID's and some crazy setup or a VPN, which would be over the internet there is no better way.

I know with DD-WRT firmwares, each interface (2.4GHz and 5GHz, along with each eth) are independently controlled. If your landlord is broadcasting 5GHz, you could take your 5GHz radio and connect it to that network, and set the mode to "WAN Client - DHCP." Then, with your 2.4GHz radio, simply set it up like you normally would with a "LAN - Infrastructure" ...

First of all we need to get some of that terminology correct.

The 10.x.x.x address that your ISP is providing is one of their internal local addresses that cannot be accessed from outside their network. The reason you can connect when you are not using your router is because you are directly attached to their 10.x.x.x network/subnet. Your DLink box is creating a new network, a 192.168.x.x, which is on a different ...

You connect the WAN port of router B to a LAN port on router A. You have to set the WAN address to DHCP and take whatever address router A issues to it. Set router B to have a network address range different then router A.

Best way to avoid this problem is: don't share your wireless with others and set a strong password for it that no one would break it. Or use keylogger to monitor them(maybe impossible)

If you are unable to make changes to the ISP router, then I would use your own wifi router, but use it as a layer 2 device, rather than as a router. All this means is that the devices that connect to your router are on the same network as if they were connected directly to the ISP router. The way to do this is to disable DHCP on your router, and connect it ...

There's a way to make Internet Sharing from System Preferences work. Make sure you set "Share your connection from:" as "Ethernet". Make sure you set "To computers using:" as "Wi-Fi" (Important: Make sure you only have Wi-Fi checked, not Ethernet. Otherwise you'll be providing DHCP service on their network, which they don't like.) Although it's ...

If you're trying to perform a monitor mode capture then you're going to need to use a direct attach WiFi device, something like a USB WiFi dongle. OS X by default does offer the ability to put the built-in Airport card into monitor mode, but if the signal is not strong enough, and you can't relocate to a better vantage point, then an external USB device with ...

I think this can be made to work as long as you have two antennas which you can control seperately (I'm not sure if that's the case for the N66U, but my AC66U allows different settings for the 2.4 and 5 GHz interfaces). Another option could be to use a USB wireless adapter to run on the router's USB. You might have to manually tinker with the routing table ...
