Public Library Wireless Connected But Internet Inaccessible?
Feb 1, 2011
t's been 4 days in a row now that I can't access wireless Internet on my laptop at a public library that I visit regularly. I have no trouble accessing wireless Internet anywhere else. For several months I have been using wireless Internet at the same library on the same laptop without any problem.Windows troubleshooting message: Windows can't communicate with the device or resource primary DNS serverThe wireless network at the library has no Authentication, it is while accessing a Web-site that it it automatically goes to a page where members have to login, however this hasn't been happening for the last 4 days. I'm able to connect to the network, but with no Internet access. I guess because the DNS won't respond. Here is what I already tried: Disable the firewall and see if that works properly Boot in Safe Mode with Networking and see if it works that way TCP/IP stack repair options for use with Vista or Windows 7 I installed Mozilla firefox.... still no luck[CODE]

I work at a Public Safety building in Pennsylvania and our employees here share a Wifi connection with a local hospital facility that is in a industrial park behind us. The room we work in is able to access the Public Wifi but only half of the room has a good connection. I went to the local computer store and purchased a Belkin Dual-band wireless Range Extender and got it all set up, now I have the Public Wifi Extention access and it will connect to it but it has no internet access. Now we have no access to the administor or the network from our facility. How do i get internet access thru this range extender? If i connect from the good half of the room to the Public wifi i have a good connection with internet access but as soon as you put it thru the extender no more internet access.

I work at a small public library and we're trying to setup wireless internet for our patrons. I've been studying VLANs, trunking, etc and going through the Mike Meyers book trying to study and learn enough to prepare for the Network+ cert. We are using a Cisco 1841 router, a Linksys SRW224G4 switch, and we just purchased on recommendation the Cisco WRVS4400N Wireless N VPN Router.

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.

Am using a RV042G with a Fiber Optic connection terminated on WAN1 It was working fine untill received a new IP pool . When we configure with the ip on wan 1 and connect the SG300 the WAN Status shows connected but no internet connection. The wan ip doesnt work. If i replace the RV042G with a Netgear Firewall router The connection works fine with the WAN IP.
The network connection is very simple. What is that is not letting RV042G work with SG300?

I have a new E4200 (running FW 1.0.3) and connected a Seagate GoFlex 1TB drive to it. The drive is recognized fine by macs and PCs. However, I find random folders appearing in my mac finder as "alias" and hence innaccessiable. There are a bunch of them scattered in random areas. On Windows those items appar as an unrecongnized incon, a 4KB size and Type file with the "archive" option checked under File "Properties". On a mac they appear as kind "alias" with a 4KB size.I also didn't notice any particular oddities with the directory name (I.e no special chars). I tried renaming them and that didn't fix it.

Region : UnitedKingdom
Model : TL-WR841N
Hardware Version : V7
Firmware Version : 3.13.9 Build 120201 Rel.54965n
ISP : Linpop
I have had my WR841N for about a year, supplied to me by my WISP. I like the router in terms of facilities but it seems to have one really annoying problem.
The router becomes inaccessible via the webpage after a random period of several days. I have at times associated the issue with occasional loss of radio broadband service but it is not always so. To try and further localise the problem I set the router up to send emails of the log to me every two hours from 17/04/2013 but today for the second time the emails stopped arriving after the 02:29 message and the router is inaccessible again. The router previously locked up with loss of broadband service on 26/04/2013 sometime after emailing a log at 02:41 on that day but had been running without issue from a cold restart at 12:25 as soon as I noticed loss of service.
Today I have not lost broadband service and so even though I am no longer receiving an emailed log or able to access the router via its webpage I am leaving well alone for the present. Some months ago when I originally noticed the web access issue I downloaded and installed the latest firmware TL-WR841N-v7-120201 and I note that there have been no further firmware releases for the v7 model.
My broadband service is delivered via radio link from a local transmitter mast and is reliable with typical download speed of 20-30Mbps and 30-40Mbps upload, seldom if ever affected by weather so I now feel the problem is inherent in the router rather then being the result of some issue affecting broadband service which has been solid since 26/04/2013
Without the log I have no way of knowing what was happening when the router became inaccessible but I attach the last 24 hours of received log below.
May 5 00:59:42 DHCP NOTICE DHCPC Send REQUEST to server d91650b2 with request ip c3cecc76

I need to access my employer's website to make changes from home. At work, I use a Mac and can use the built-in tools in Finder to quickly type in the ftp and log in. However, if I try to go in through Filezilla on a PC, the server never connects. I have tried using SFTP and CyberDuck as a web dev with no luck.

I bought a gigabit NAS to replace my existing 100Mb NAS. After copying the data and users from the old box to the new (during which both NAS boxes worked fine) I renamed the old one to BACKUP and gave the new one the name of the old, FILE_SERVER.

Up to this point, all the computers on the network accessed the e-mail server via the Windows name of the PC running the e-mail server. However, one of the PCs will need to access e-mail from the WAN soon as opposed to the LAN, so I switched the server name in Thunderbird (e-mail client) to the actually fully qualified domain name of the server (registered at NO-IP, which redirects to the e-mail server at home).
The problem I am running into is that all the requests sent for IMAP or SMTP are being blocked by the router. That's even though I added port forwarding rules for them. The logs show messages similar to the following:
"Blocked incoming TCP connection request from 216.168.101.68:51291 to 216.168.101.68:143"
It doesn't make a difference if I change the endpoint filtering to "Endpoint Independent" either. Any thoughts of what else I can try? DMZ is not an option.

I've got the DIR-825 2.02. I had an issue where if you did change the IP adress default 192.168.0.xxx to something like 192.168.yyy.xxx, the configuration page was becoming inaccessible. It was super slow, was displaying the wrong pages with missing images and wrong page formating. I had to reset the router to default and then it was working fine.That seems to have been fixed since 2.05. Now you can change the default ip adress to anything you want and the configuration or setup still work fine.When I am on LAN, the setup page are displayed almost instantly. By remote, it's super slow.

We have recently purchased a Cisco Small Business Pro SRP 527W router, all seems good and it is running smoothly, no disconnections or sync issues like our last router. However, after a certain amount of time the web management interface is unavailable through the browser (accessing it via 192.168.1.254 or the alternative we set-up 1.1.1.1) It is totally unavailable and timeouts in the browser yet there is still internet access and network is still alive. The web management interface was accessible before though and the only solution I have been able to do to access it again is to reboot this router.Could it be possible that because port 80 is forwarded to a different IP it interferes with the Web management interface? And how wcould the interface port access be changed?

This is my current config:
Offsite Central Office
-------- ----------------- --------------- ------------------------------ ----------------- ---------- -------
| PC | | 3560-EMI | | ASA501 | | Comcast Business | | ASA5520 | | 6509 | | PC |
-------- ----------------- --------------- ------------------------------ ----------------- ---------- -------
I've got a VPN L2L tunnel between my offsite and my central office. Everything seems to work most of the time, but every now and then i loose connectivity to random devices.for example, right now I cannot ping the interface on the 3560-EMI, however i can ping the PC on the other end of it. A few minutes from now, the 3560 will be pingable and i will probably notice another device that is no longer accessible.It almost seems as if the ARP table is corrupt or inconsistant. Another example would be 2 separate PCs on the Offsite side, I can ping one but not the other. If i telnet into the 3560 i can ping both PCs without issue, but once i get to the other side of the ASA5520 I no longer can see both devices...A few minutes later the second PC will be visible again from the Central Office.

Experiencing a strange issue with v3 hardware. After a short period of time, I cannot log into the web administration - either locally through standard port or remote through non-standard port get login prompt, enter correct username & password, page refreshes with blank background and first page (status?) never shows.power cycling the router restores access to the web administration page, for an uncertain period of time before it barfs again.
I was running older firmware, updated to newest 4.2.1.02 (?) and same problem. Only thing that is better is the internet didn't completely lock up when I tried to access the administration page, like it did on the older firmware.

One of our vendors requires using a public ip address to setup a site-to-site IPSEC vpn. We only have one public ip address and that will be used for the vpn endpoint and for internet access for the local network. I've setup policy NAT from our local network to the outside interface. I'm also using the outside ip address for the crypto map. The tunnel setups successfully and the Tx count increases anytime I try to ping the remote network, but the ping fails and the Rx count does not increase. According to our vendor, we should be able to ping the remote network and connect using port 443. When trying to connect using port 443, I see a SYN timeout in the logs. I'm not sure if the problem is on their end and they're rejecting our traffic, or if something is misconfigured on our end. I'd like to make sure that I have everything configured correctly before I go and point fingers at them.

I have this 3750 stack where all ports are configured as below.The data runs on VLAN 1 and the voice runs on VLAN 100.

The PCs and Polycom VOIP phones are plugged into the switch and they work fine.However, if I plug printer(s) into the ports, they cannot be accessed.I have to end up removing the trunk mode before it can work like below.

Basically, I have a LAMP server for a small landing page for myself.It was all working fine until I got my new router.Now, I can only access my sites on a LAN.All the ports (3306, 80, 22) are opened and multiple port checkers online says so.I followed some of the basic steps mentioned in this forum such as firewall settings such as:
"Port and Address Restriced"
disabled QoS
Enabled Multicast Stream
enabled DNS Relay
set DHCP range to avoid any IP conflicts
Ive even temporarily removed all firewalls completely to make sure that is not the problem.

Studio 1558 using Windows 7 64-bit with Netgear DGN1000 router
I can access almost every website with no problem however two sites in particular time out unless I connect an ethernet cable between the laptop and the router. Then there is no problem, the site comes up immediately. The sites are skytv.co.nz and asbbank.co.nz.
I have tried different browsers but that does not make any difference. I borrowed a Toshiba laptop and connected to my wireless network and that had no problem connecting to either site wirelessly so there must be something wrong in my Dell laptop. One difference I noticed between the Toshiba and Dell laptops was in Wireless Network Connection Status the Connection Speed for the Dell is 65.0 Mbps whereas the Toshiba was 150.0 Mbps. I'm not sure what this means and whether it is relevant.
I have reduced the wireless MTU to 1400 from 1500 but still no connection on those sites. It is a nuisance to have to use the ethernet cable to visit two websites when the wireless works fine on every other site.

I have a brand new SG500-28P sitting on my desk.
The swtich is configured and going to operate in L3 mode. All ports are still assigned to the default VLAN ID 1. I have created several new VLAN's. Once I configure and aplly an IP Interface to a certain VLAN the swtich becomes inaccessable right away. I am pretty sure I am not pulling my own VLAN under my connection. Every port is inaccessable. I have to pull the power plug and restart the swtich with its saved configuration. Even when I add another IP interface to the default VLAN 1, same issue. I have tried lot's of things, but can't get it to work properly. I have just upgraded to the latest firmware.
I have configured dozens of SG300 swtiches which is very easy. This one does not work with me.

I'm adding another router to my home network to extend my WiFi range. (Linksys e2500.) I'm trying to change its IP from the default 192.168.1.1 so that it doesn't conflict with my primary (dhcp) router.
To isolate matters I've reset the router to factory settings, turned off my mac's WiFi and then connected the Mac to a Lan port on the router. Now I can view the router's admin page at 192.168.1.1.
Now I change its local IP to 192.168.1.3 and leave the subnet as 255.255.255.0. The router reboots and after several minutes is inaccessible at any IP I try (still hardwired to the Mac with WiFi off). Ifconfig doesn't show the router and the only way I can get it back is to factory reset it again.

I just set up my new HSI service with comcast. I am using a Motorala 5101 Cable modem. No issues with the ethernet connectivity of course. I set up a wireless network with a Westell router. Just now I found the westell 7501 router I use is meant for DSL service.
However I am able to go as far as connect to the wireless network without a hitch. The only problem is that there is no internet activity happening.
