Home Network :: TL-WR340GD - Port 80 Blocked At Random Points Of Time?

Apr 15, 2012

The problems looks like this: I'm able to browse the web without any problems until at random points of time - might be 2 hours after I turn on my PC or 5 or even half an hour the port 80 gets blocked - actually more like it hangs it self. As whatever I try to open i get "waiting for response" going and going. It's not even returning "page not found" error or anything. To top everything all other ports work fine - i can use https, ping run tracert - no problem there.

I've spend two days looking for some answer on the web but came up empty. I've scanned for malicious software with ad-awar and malwarebyte anit-malware - nothing came up. After restart of the pc everything comes back to normal but its frustrating needing to do that every now and then.

My home network looks like this: I have some broadband modem that is connected to local wifi TP-LINK router (Model No. TL-WR340G/TL-WR340GD). There are four devices using this connection - two pc's (laptops), android phone and android tablet.

Home Network :: SSH When Port 22 (and Others) Is Blocked?

Sep 15, 2011

I have a home server running CentOS 5 and is accessible over SSH (port 22).When I am at work I am behind a firewall that blocks all ports except the ones needed. So port 22 is blocked to the outside world.Is there a way for me to get an SSH connection to my server? (ie: SSH tunneling or so?)by the way, websites with advanced web based SSH javascript(s) such as serFISH are blocked as well.

Site Being Blocked From Home Network

Mar 5, 2012

This one specific website that we have been trying to go to it is a university of phoenix student log in site. From the three laptops and ipad 2 and samsung galaxy tab. The site will not load on any of our computers. We have logged on from this computers at the same time on this same network before and it always worked. She also logged on to it last week and worked fine. We logged on from a different network and it worked there but we need to get it working here. It is obviously the router or modem here, but i factory reset the router and it is still doing that. When we can get it to load it is real slow and it loads like it

Home Network :: Random Network Drops / Disconnects Services?

Apr 15, 2011

I've been having some issues with my network connectivity for a while now, and I haven't been able to figure out what the problem is. I run a wired connection to an Ethernet port in the wall of my university dorm. I have verified that it is not a global network issue or an ISP issue; this problem only happens on my PC.My network connection drops/disconnects randomly throughout the day. When I say disconnect/drop, I mean that all attempts to ping or access the internet fail. A few minutes pass before the Network and Sharing center task tray icon shows a warning sign saying that my computer could not connect to the internet.This is temporarily fixed by doing an ipconfig /release and ipconfig /renew, but I have to execute these two commands about 2-3 times a day on average.

There is no exact interval between the disconnects, nor does it happen when I am running particular programs. The disconnect happens regardless of what I am doing at the moment (gaming, browsing the internet, leaving the computer idle).A month back, I installed some Windows Updates and suddenly my internet connection was almost completely broken. I was experiencing the same issue, but much more frequently. My internet would die within 10 seconds of executing any download, but Windows wouldn't recognize that something was wrong. At first I thought the ZoneAlarm, Avast!, or the SafeConnect (as required by my university) services were causing trouble but uninstalling/disabling these services did not fix the problem.I also tried reverting to my default ethernet drivers, which did nothing. I uninstalled and reinstalled multiple versions of my drivers to no avail.However, the internet worked just fine in Safe Mode with Networking, so I cross-referenced the processes/services running in Safe Mode w/ Networking against my normal startup, guessing something else was at play.After some poking around, I discovered that disabling the Server and Browser services permanently fixed the issue of instant connection death. But the initial problem I described still remains;random, less frequent internet connection drops.

Home Network :: Getting Random Moderate Nat Sometimes - Other Times Its Opened

Nov 25, 2012

I keep getting random moderate Nat sometimes, other times its opened. I have made a static Ip and port forwarded 4 ports that xbox uses. 88 udp..3074 both...53 both...80 tcp... Now when i test my connection on the xbox dashboard a message will come up saying make sure my UpNp is enabled, which it is and it tells me to make sure port 3074 is enabled which it is. I have restarted both my modem and router multiple times to try and fix this.

I have a linksys cisco e4200 and I recently updated its firmware which i thought would possibly fix the problem.I have talked to linksys but no luck.I have talked to my internet Cox Communication but they tell me its the router and i believe it is because when i directly connect my xbox to the modem i never get the moderate Nat. I have also talked to Norton about my virus protection because I thought maybe it was blocking some ports, but they disabled it and I still get the message.

Home Network :: Setting Up Wifi With Multiple Access Points?

Jan 27, 2012

Well this process is self explanatory, setting up the network is easy but im running into trouble with my wireless devices connecting to the strongest signalIm not exactly sure if there is a fix for this yet or if they have not made a protocol to fix it. I have a big house with solid wall in which i have setup 3 wifi's. 1st Modem/wifi Router, 2nd Wifi access point, 3rd wifi access point. Now the problem im having is moving between the access points my devices such as my ipad are changing from one access point to the next whilst moving throughout the house (that is until it loses the first signal I believe or you turn your ipad wifi off/on so it reconnects back to the strongest/closest access point).

Home Network :: Multiple Access Points Connected By Wireless Bridge?

Sep 27, 2011

I have a router that is capable of wireless N at 5.0GHz but can't run simultaneous with it's 2.4GHz band a/b/g (Cisco Linksys E2000), so I have a second router acting as gateway for my b/g devices (and a few wired only that are nearer to it). They are connected LAN port to LAN port with 50ft of cat6 and the DHCP server running on only one router. I know this is pretty standard for multiple access points, and it works very well. But I'm moving, and in the new house, the internet access will be on one floor with the wireless N router, and the other router will need to be in the basement on the opposite end of the house, and running networking cable through the floor and walls is just too much trouble. My question is, can I replace the previous wired method with a wireless N bridge attached to the LAN port of the router in the basement and have it function in the same way as it did when it was wired, with only the DHCP server running on the wireless N router, and all devices attached to either router able to see each other? I would assume so, but I would like to know from anyone who has experience with it before I go buying the bridge.

Home Network :: Setting Up Networks With Multiple Locations / Wireless Points?

Feb 11, 2011

setting up networks with multiple locations and multiple wireless points.For example: My sisters' home has here modem in her main computer room, it has a Belkin router hooked to the modem. Then a line goes from there to my nephew's room where I tried to expand their network by adding another router. I really just wanted an access point, but they don't seem to sell these as much as they used to. Anyway, I had it working, but it was two different networks, NETWORK1 and NETWORK2. So they had to swap networks when moving around the house. what would be the best hardware setup to provide both sides of the house with some Hardwired access as well as wifi access? Right now, we have two routers, a DIR615 (or something like that) and a Cisco E1000, and again hardwire going from the main computer room to my nephew's room.Also, in my house, I have lots of stuff... I have an Actiontec Router from FIOS, feeding a small hub as well as a switch in my main room. Which then feeds a Ps3, Wii, laptop, Denon reciever, and Access Point... and also feeds my Apple TimeCapsule, which also feeds my printer. My wireless devices range from cameras, iphones/ipads, and a wifi unit (I forget what it's called, but it connects my DVR wirelessly to my network, and the DVR itself doesn't have wifi).

my question about my setup is, should everything be on one network... as in let the ActionTec handle most of the duties and use switchers and accesspoints to extend the network. Should everything be on the same wireless network and channels? Like if I used my access point to extend, do I want the same settings as my main wireless router, and would that be the same for the Apple Airport Extreme?Also, does having all these wireless networks going create any kind of hinderance on my performance. For example, the PS3 has some sort of wifi in it... it produces a SSID, but I never connect to it. Should I make sure that's off? And in my main room, should I go with just the AirPort extreme over using it and the Wireless Access point.

Home Network :: Advanced Home Network Setup (3 Subnets) And Port Forwarding?

Feb 24, 2013

I have a Time Warner Cable business class service with no static IP, with a wireless modem which is plugged to a CAT5 distribution panel. On the jacks (2 other rooms on the house) I have a Linksys E3000 and a Linksys Valet router for signal boost and gadgets usage (TV, cameras, etc).The main router (TWC) has it's own external IP which TWC assigns to me and internally distributes via DHCP the range 192.168.0.x. With that said:

- The E3000 has a IP -- this is fixed setup on the TWC router (ubee brand) by MAC address
- The Valet has a IP -- this is fixed setup on the TWC router (ubee brand) by MAC address
- The main router has the as the gateway and web-interface

Whenever I connect something to the E3000, it is distributing the 192.168.1.x range and the valet 192.168.2.x range.That works perfectly for my home based business until I decided to use more stuff on the network such as a IP printer, IP cameras, etc.

- The IP cameras are connected to the E3000 due to signal strength and I have manually assigned them the and IPs and ports 9001 and 9002.

- The printer is connected to the E3000 and I have manually assigned the IP

Issue 1: Port forwarding On the main router (TWC - UBEE) I have tried to setup a port forwarding by informing the Local IP as (E3000 IP), Internal Port 0, Public Interface IP (, Ext Start Port 9001, Ext End Port 9001, Protocol - Both, Enabled Yes. On the E3000 I did the same config (screen shot attached e3000.png).This is not working properly. I can't get into the camera.

Issue 2: Printer/ The printer is only accessible if I connect to the E3000 (because it is on the 192.168.1.x network)

Issue 3: How to configure all the devices on the same subnet? If I want everyone to be on the 192.168.0.x network, how to configure properly the E3000 and the Valet? I have tried to force them into the same network but it would not work properly. It would not get an IP from the UBEE router (main).

Cisco Switching/Routing :: 2975 Not Handing Out PoE Power To Phones And Access Points At Random Times

Oct 22, 2012

We currently have around 150 2975 switches and have had problems with it them not handing out PoE power to the cisco phones and access points at random times.  There is plenty of power left for the switch to use.  We have at least 15 that will be running fine for about a week and then all of the devices that use PoE power will shut off and will not come back on until we reload the switch.  If you console in there aren't any messages that pop up and if you look at the port it just shows on connected or will show IeeePD in the power inline.  We have contacted Cisco TAC and they just RMA them.

Small Network / Random Computers Lose Browsing At Random Times?

Dec 29, 2012

Network running about 60 computers, most of which are running windows 7 professional. Some are on a domain, some are not.At (seemingly) random times, some computer on the network will lose the ability to browse websites (including the web interfaces of networked devices). I can't identify what circumstances cause this to occur. I only find out about it when someone calls me.From the affected computer:I can ping sites I can ping our Cyberoam UTM (which acts as our DNS, DHCP, and firewall)disabling/enabling connection doesn't fix the problem releasing/renewing ip doesn't fix the problem flushing dns doesnt fix the problem uninstalled antivirus on two test machines, problem still randomly manifests.replaced the Cyberoam with newer model users have claimed that if they wait a long period of time (40+ minutes) the problem sometimes resolves.rebooting the computer resolves the issue until it randomly occurs again changing the computer's mac address also resolves the issue until it randomly occurs again.

D-Link DIR-655 :: Time Server Getting Blocked / Double Routers

Aug 30, 2011

I'm new to networking (at least at this level) and need some guidance. First, I have an Actiontec MI424WR (Rev. F) Coax Verizon Fios modem that I use as my home networking wireless router.  From a LAN port on that I've connected a cable to the WAN port on my DIR-655 which acts as my gigabit office hard wire/wireless router.  I need to keep the home network and the office network separate.All of my computers are Windows, either 7, Vista or XP.Connected to my Dir-655 on the office network are 2 wireless computers, a printer, an IOMEGA 1TB Home Personal Cloud NAS HDD, plus 2 desktop computers.The DIR-655 is set with a static IP address matching the range of the Actiontec. The DIR-655 is set for DHCP for the devices on the network (although 2 of the computers have static IP address).

When the DIR-655 had a Dynamic IP address set by the Actiontec, the IOMEGA NAS HDD kept losing connection with all the devices on the network. Only after I set the DIR-655 to static IP did that stop and everybody started to play nice. I'm not sure why that would make a difference, but it did.But regardless of whether it is set to dynamic or static, no computer on the network or program, even third party programs, can connect to ANY of the time servers out there... and I mean any of them. I've tried at least 20 or more of the standard and not so standard ones.  The DIR-655's time is off, and it is set to get time automatically.  None of my computers, or my IOMEGA NAS, can access time.  The Actiontec, though, seems to be set correctly.Everything connects to the internet just fine. Web, email, auto product upgrades. Fine. So far it's just the time server thing which troubles.I done everything I know how to do to enable Port Forwarding through both routers for NTP > UDP 123 since that is the standard port for the Network Time Protocol, but I could have easily screwed that up.

Home Network :: Two Computers Can't Be On Router At Same Time

Aug 13, 2011

I'm using Comcast cable. I have a motorola cable modem. I run that into a Netgear 8-channel router with wireless (that's 8 physical network sockets).I have had these devices hard-connected to the router up until today and everything has been running fine:

* My Desktop (desktop running Windows 7 with Gigabyte motherboard and built-in Realtek NIC)
* T-Mobile VoIP device
* My Laptop (old Alienware running XP with generic NIC)

Today I took my old desktop motherboard from a year ago (Gigabyte motherboard, but not the same as My Desktop, built-in Realtek NIC), gutted it out, replaced the hard drive, got it running Windows 7 and set it up for my kids. Got it connected to the Internet early this morning when my machine was off and it ran fine.While it was updating, I fired up My Desktop and the router stopped working, all machines lost Internet, and I was at a loss.After some troubleshooting, it turns out that if I have My Desktop and the Kids Machine connected to the router and running at the same time, all devices on the router lose connection. I can have the Kids Machine on with the T-Mobile device and My Laptop and they all work. I can have My Desktop on with the T-Mobile device and My Laptop and they all work. But as soon as My Desktop and the Kids Machine come on together, everything gets hosed.The router is set to reserve different IP addresses by Mac Address for every machine. And I've verified that My Desktop gets its IP address correctly, and so does the Kids Machine. They are different IPs.I (usually) know just enough about networking to get a home network set up.

Random Request Time Out When Pinging Gateway IP

Jul 6, 2011

I've had some issues with my internet connection lately. Occasionally I would have connection interruptions even when I am just browsing the web with no downloads in the background or anything like that.The strange thing is that connection fails right at the vey beginning - if I constanly ping the gateway, I will see that among the continous pings of 1ms or less, every once in a while I would have several "request time out" messages.My laptop is connected directly to the router with a 6 feet cable. I replaced the cable and it still happens.What I also noticed is that if I am online in the MMORG I am playing, I can stay online for long hours, however when I start browsing the web, I would get disconnected pretty soon. So I think somehow browsing (and downloading at high speeds, which is understandable) somehow triggers these timeouts. I dont know what to make out of it.

Home Network :: Wireless Loses Speed Over Time (at College)

Oct 25, 2011

Using my Acer Aspire 5750 at school my wireless connection speed will drop from around 4 Mbps to .30 Mbps. The speed will start out fine from startup and degrade over time. This happens only at school, and only on this laptop using this wireless card. My home network hold its 3Mbps down just fine. My campus has two wireless networks, one is WPA enterprise encrypted and one is open, both exhibit this behavior. Using my network credentials on another machine or using a different wireless card this machine works fine.I've updated to the latest driver and rolled back to previous ones.

This is happening on a fresh install of Windows and on Ubuntu live CD so it is not malware or something along those lines. Spoofing a different MAC address does not change this behavior. The devid is PCIVEN_14E4&DEV_4358&SUBSYS_E040105B&REV_00

It is a Broadcom Wireless N...

What could be causing this problem? Does the NIC not like the access points or vice verse? Are they any settings I should tweak? The drop in speed happens no more than 10 minutes after boot and occurs in both Windows and Ubuntu. I should add that other students don't have this issue so it is not a network wide thing. Other students get around 4mbps down continuously. Using somebody elses credentials on this machine doesn't work either.

Lenovo Y 560 - Computer Has Been Disconnecting At Random Time For 30-60 Seconds

May 3, 2011

I'm using a Lenovo Y 560 using a wireless connection to an Apple Airport extreme. I have been using this set up for a few months without any problems. However, recently, my computer has been disconnecting at random time for 30-60 seconds. There isn't any lag before or after and this occurs when gaming or browsing. The weird thing is, there are about 15 other PCs and Macs using the airport and none of them are experiencing this problem. I used my 'one key recovery' button and restored my computer to the factory default and updated/reinstalled all wireless drivers and the problem still persists. At this point I'm stumped, any suggestions?

Home Network :: Connection Between Router And Cable Modem Goes Off At Specific Time?

Lately I've been experiencing connection problems between my router and cable modem. Every night after 11:00 PM EST, my Internet connection sporadically goes out. I called my ISP who said there was nothing wrong on their end. Plugging directly into my modem allows me to access the Internet. When I wake up in the morning, the connection is back until 11 or later again. I ran WireShark but I'm not sure what to be looking for. There are a lot of random things from the LLMNR protocol like standard query A zmtvrjaql.

Port 80 Is Blocked By ISP?

If I port forward my site at my web server to (let say) 85, when someone type [URL] (with 80 by default), will it be somewhat in the cloud or some server to NAT 80 to 85 at my site? In short, can one type [URL] instead of [URL] ?

The distance between the house and the first hall is approx 1 road width distance.ISP is Virgin and the internet was installed this year hence has the latest Virgin Home Hub.I am aware that i probably require 3 wireless access points (1 for each hall).The first wireless access point will need to be connected with a RJ-45 cable running from Home Hub. Can i connect the Wireless access points up together or do they all need to come from the ADSL hub?I am not sure what Wireless access points would be best and how to go about connecting this all up

I've opened the same port on my firewall in windows 7. I've disabled my firewall completely. Everything should be cool, but still, checking with canyouseeme.org and asking friends to join. It is still blocked. It simply doesn't work.. I checked my router for any firewall but couldnt see any.. So yeah I'm 100% I fixed it on the router, unless someone is gonna tell me that there is still an option in the router that might fix it.. but I think I did something wrong in the firewall..Although I have been trying to get this to work all day.. I'd rather get some advice on the firewall or other options in my router. Btw, I am using AVG free edition, and I am pretty sure there is no firewall in that version, but there might be something I have to disable in order for this to work ?

Port 3074 Blocked When Launching Game?

Oct 20, 2011

I'll try to keep it short. On this Games For Windows Live game (Dawn Of War II) I can connect to and play on the internet just fine. Enabled port 3074 and 88 so that GFWL wouldn't have any problems connecting to my computer. Port 3074 has an issue however.With the PortForward testing program (Open Port Check - PortForward.com), whenever I check port 3074 outside the game, both UDP and TCP show green and are forwarded correctly. However when I'm in the game, alt-tab, and run the test again, it shows UDP red after testing, indicating it's not forwarded correctly.I think I know precisely what the problem is; either something in GFWL or the game itself is blocking port 3074. But why it's doing this, and how to find out what it is, I really have no idea.
