I have battling this issue since I bought this router, at least 2 years.
PC XP Wired
2 Acer laptops Vista wireless
All DHCP reserved
Security using wpa_psk
Not sure what other router info you need. All are connected to the internet, but can't see each other on the LAN. We can see each other from time to time. Sharing is allowed. Passwords are shared. I can power off the router and the network will be fine for about a day, then gone again. Workgroups are the same.
I already mention on another topic that I have problems with my Nokia 500 wireless connection with the router. From time to time (in some cases after few seconds since the connection was made) it's loosing the connectivity with the router. Normally it's loosing the connectivity when the connection it's not used by any phone application.Is this normal? I want to mention that the power saving function of the phone it's disabled so the problem can be from the router.I already tried TPIK only but no success.
The router has the following setings:
- Enable Auto Channel Selection - checked -Transmission Rate : automatic - WMM Enable: checked for QoS - Cipher Type : auto - PSK / EAP : PSK
- Beacon interval : 100 - RTS Threshold : 2346 - Fragmentation : 2346 - DTIM interval : 1 - Preamble Type : Short - CTS Mode : Auto - Wireless Mode : n/g/b - Band Width : Auto
I've purchased and am trying to use a Dir-655 rev. B, running firmware 2.00NA. I have two hard-drive style Apple Tv's. They can see my wireless network, and after putting in the passcode, can connect. They at this point are visible to iTunes and can play any/all of my content. However after a period of non-use, they go into standby mode, and upon waking, can no longer connect to my network. I have to re-do the wireless each and every time
I had to reboot my Dir 655 because my 2 wireless laptops wouldn't connect to the internet. Once I reset all of my static IP settings in the dlink admin tool the wireless laptops work fine. The problem now is that I can't connect to the internet on the computer that is hard wired into the router. I recall once before having to adjust the TCP/IP settings in the Network settings, but don't remember exactly what it was the I had to do.
I have a EA3500 and my wireless computers keep getting disconnected about every ten to fifteen minuets. I have the newest firmware. My android phone also is having the same issue. My internet connection is stable and my wired connections do not get disconnected at all at any time. Is there something I need to setup in the configuration to resolve this?
I have 2 older xp pro tough books that connect to my domain via a pair of versa vx 400 access points. automobile technicians use these computers to communicate with cars via a separate wireless card and WiFi device (SPX MVXI) that broadcasts a wireless signal.they always connect just fine to the network but sometimes they drop there connection and don't rejoin which screws up my scheduled tasks (nightly upload). They will reacquire the connection every time if i select it again manually in the windows wireless config.here is what I have done so far
1. set up exclusion range in DHCP distribution on my DC
2. set the laptops up with static IP's within the exclusion range.
3. configured the laptops to auto connect to the network even when its not broadcasting
4. set the access points on channel 7, and the devices on 1 and 11.
I have done a lot of research on this issue, a rep from versa told me that Intel proset wireless isn't very compatible with there product which i this is BS since it does the same with with the netgear WiFi PC cards.
I have three laptops (running ubuntu with different kernel versions) with wireless adapter Intel Corporation PRO/Wireless 3945 ABG. Laptop A ----- Laptop B ----- Laptop CI created an adhoc connection in laptop A with: Essid: 'ad_hoc', IP address: 10.42.43.1, Subnet: 255.255.255.0, Gateway: 0.0.0.0, Now the laptops B and C can see the wireless connection 'ad_hoc' and I can connect to them after setting IP 10.42.43.1 and 10.42.43.2 respectively. So, I created the adhoc connection between 3 laptops. Now, I wanted to check the bandwidth between the different paths. The tool iperf was what I used for TCP bandwidth calculation. The bandwidth between A and B was around 4.5 Mbps , between A and C was around 4.0 Mbps but the bandwidth between B and C (B being server) was 677 kbps whereas C being server was 3.99. I don't understand how can the bandwidth drop so high when B was made the server. The system adapters are identical.
Have Win7 and XP systems in my network wire connected to the router. When IP of both systems are not reserved, each computer can see other network computers and devices, five in total.A good thing that both systems get each time same IPs which even got not changed since I upgraded from E1200.When I reserve an IP for each system exactly that they currently have, both systems loose ability to see other network computers. Network shares not affected, I still can remotely access my XP box remotely from my 7 via RDP by computer name. WDTV Live wirelessly connected to the router can get/update its IP address (no connection issues) but same as others cannot see network resources.
Tried different ways, rebooted, finally ended up with device reset pushing the button.The next day I managed to reproduce the issue, but was able to revert by disabling/enabling of DHCP server.Another issue I got with an external HD connected to the router when some files got converted to folders by uTorrent started from that drive.I had to use Unlocker application to be able to delete folders converted. I can just assume that issue because of anonymous access was enabled to the external disk. No problems when same HD connected to PC USB.
I'm having a problem with my WCG200 wireless gateway. I can sucessfully use it to connect to the internet using the wireless feature but only for a short time (10-30min at a time). Eventually, I loose the connection. I'm not sure if it's a modem issue or an ISP issue but only one of my two laptops has this trouble.
Symptom: Connecting with a Dell Lattitude E5520 laptop It works normally until the "US" and "Online" LEDs turn off and only the DS light is left blinking. At that time I no longer have a connection to the internet. Once I cycle power on the WCG200 it re-connects and works for a while, then the same issue repeats. I cleared the modem log and let the failure occur again to record the fresh log.
I attached the Modem Log in case that would troubleshoot. I've got the security of the modem set to allow the laptops MAC addresses and using WPA-personal / TKIP encryption. I never had this problem until I started using a new laptop, I'm starting to suspect that my ISP is disconnecting that laptop for some reason ?
We are having problems with a two router 3945 in HSRP and a switch 2960.The two routers are connected to the switch 2960 through differentes ports. The problem is that we loose connection between the router and the switch.When we excute the command: show cdp neighbor at router, it shows nothing.If we try to make ping to the 2960 switch it is no reachable.If we make ping to the other router 3945 it is not reachable.All other function of the router are o.k.We are attaching the IOS of the routers and switch 2960 and a document in which make reference to a BUG in which mention about arp overwrite due arp attack which produce DoS.
My Dell Studio 1558, specs: Core i5 2.4Ghz, 4GB DDR3, 640GB HD, Radeon 5470 has a very weird problem. Occasionly, either once a week or twice a day the network functionality will literally dissapear. The icon still displays on the tray but when I click it nothing happens. If I try and connect to the internet it will say there's no internet connection. Also if I try and open the Network and Sharing Centre explorer stops responding and has to be restarted. If I try and shutdown the laptop it will just hang on the Shutting Down splash screen and has to be forced off. The laptop is still IN warranty however I want to fix it myself as I cannot face Dell
I thought that there are more security issues than LAN issues, I have a network with 11 computers of which 1 is SME server and 10 are clients (mainly 256MB DDR1 tech machines withceleron D processors, onboard VGA and sound; there are few 1024MB DDR2, AMD Sempron LE processors). All clients have XPSP3, .NET framework 1.1+2.0, Office 2003, AvastFree 7.0, Mozilla Firefox 7.0 and several utilities not very important. Every client has 2 users (Admin and User) on Local Machine and 1 on DOMAIN (UserDomain). Both User accounts are limited. First, all computers were in same workgroup and not part of DOMAIN. In that time, printers on clients were shared among themselves and worked flawlessly. After joining the clients to the DOMAIN, the work continued without issues. One day, I have changed the name of the SME SERVER computer and the issues have started. Several clients can not connect to those shared printers, even others are using them well. When I want to add shared printer I can not browse the particular computer on which the shared printer is (through ADD PRINTER wizard). I manage to do it writing the full path of the particular computer and there I can choose the printer.
After selecting it, username and password is required to finish the adding. Of course I use the Admin username ad password, and after typing it error message pop up (printer is unavailable or can not connect to it). After this I close all windows, start the adding procedure again, and then I can add the printer normally. The problem continues, because, on those computers on which I have had this complicated way of install, after several days shared printers refuse to print saying Access denied. Then I have to delete the printer again, install it twice and hope to work after that for a weak at least.
The problem is getting bigger, as on one client computer I can not print from browsers (Firefox 7, IE 8) but from Office there is no problem. Of course I have checked other topics about this and use setups-modifications-advices but they did not solve printing problems. I have even reinstalled that computer, but the problem remains.
I have several laptops at home that connect via wireless connection tot he DIR_655. Using the MAC address of those laptops, I want to prevent them from going to certain websites.Under 'Advanced" and "Website Filter", I addes several domain names (websudoku.com for example). I selected "DENY computersaccess to ONLY these sites". I then saved settings.I then went to "Access Control". I clicked on "Enable Access Control".I clicked on "Add Policy" to cdreate a new policy for one of the laptops.When I boot the laptop and go to one of the websites, it still allows me access. The URL/domain name is correct.
I have two laptops which connect to the router via wireless. This router is wired to the modem. I can connect each laptop to the router then make an internet connection. This works fine. But if one laptop is connected to the internet, then the other cannot. I have to disconnect the first laptop then reconnect with the second.
I have had this scenario working in the past and can't remember what I have to do to enable both laptops to use the internet connection at the same time.
I have a Cisco 1811W that after several years in service suddenly stopped allowing any wireless connection to laptops on the domain. It allows hard wired connections and devices that are just using the wireless hot spot like iPads and Iphones but not devices on the domain. These same laptops connect wirelessly without issue at our other facilities which use the same hardware.
Here is the config file of the router in question...
router#show run Building configuration... Current configuration : 11776 bytes
Have 2 laptops that use wireless internet. The Toshiba cannot make a connection to the internet (says it in not compatible), but if the HP laptop connects to the internet then the Toshiba will. Both are running windows 7.
I have a Linksys WRT110 wireless router that has never given me any problem. All of the sudden, after a storm blew through yesterday, none of the laptops in my house (PC running Vista and Mac) will recognize my wireless network. I have a desktop computer and BluRay player hardwired to the router and the internet works fine on them through the router.The problem is not that I can't connect or lose connection, the wireless network isn't showing up as existing anymore, like it has disappeared.
I have one WLC 2504 with 188.8.131.52 code and 4 APs 1142 in Flexconnect mode all of them are in one group with 2 SSIDs in two differents VLAN:
-Admin VLAN 151 -Corporate VLAN 158 -Guest VLAN 159 -The auth is 802.1x using an ACS ver 4.2
I connect my Laptop to the corporate SSID and start to have access to web services, intranet services, etc but arround 15 25 min after i connect i lost connectivity to my GW and all the services but i still have my IP info. I do some tests on MAC books, Laptop with Windows XP, 7 and 8 and its the same for all. I config one switch port in the corporate VLAN and i never loose connectivity.
If i reset the WLAN connection all start to works.The ports in the SW are in trunk mode and almost always the APs are in connect mode.
I have the D-link DIR-825 router with the dual band, it's never caused me problems, but my wireless laptops can't use it anymore, at first they couldn't even see the SSID even though it was broadcasting. I fixed that and now they connect to the internet but no web pages load. The strange thing is my desktop, itouch and ps3 all connect to it fine. I've tried everything I know how but i'm just stuck now.
I have 2 Laptops connected wirelessly, 1 Vista, the other Windows 7. The Vista laptop seems to be dropping the connection,when I look at 'Network & Sharing Centre on the Vista laptop, it's telling me signal strength excellent but with a red cross indicating there is a break between me and the internet. HOWEVER, the windows 7 laptop (on it now) is working perfectly OK!!
I am using WRVS4400N in our company as a AP only. Before some time, when majority of wireless clients were computers, everything worked fine. But now, when mobile devices are in majority, something strange is happening. While portable computers still work fine, smart phone and tablet have extreme problems.
Although there is indicator that WiFi is connected and signal is strong, there is no guarantee that there is an internet access. Most of the times there is none. You can fix this by simply disconnecting and connecting WiFi on mobile device, but after a while, internet will be inaccessible again. Or you can wait and eventually you'll get to the internet access again.
I have a small network, about 35 computers.There is 20 LAN PC computers (they use dns, active directory, dhcp), and there is 10 laptops. They connect on same D-Link wireless router( radius server authentication).After most of laptops is operational(connected on wireless router and on domain ), same two laptops always disconnect, and they can't regain connection . All laptops also get their ip addresses through dhcp.I tried all kind of wireless router configuration, I don't think it is dhcp or dns server problem, remote access policy is also very simple
We recently acquired an internet connection. Connecting via LAN works fine for me but not to my room mates. We're all using Windows 7. Windows troubleshoot it and says "Local Area Connection doesn't have a valid IP configuration" on their laptops. What should we do?
my computer is a laptop and its about 3 years old. Ive been experiancing problems with my internet connection...It seems that it is fluctuating between local and internet to just local every 5 minutes or less. Usually I fix problems with my software no problem this time
Not too much networking savvy - but here goes. Want to use router as local lan - no wireless. When router is connected to laptop via RJ45 I loose my ability to connect to sites via browser. IPconfig shows wireless adapter at 192.168.1.3. When router is attached it's ip is 192.168.1.1. Disabled the wireless in the settings but no dice. When the router was used with DSL it was set at PPPoE but now that I'm just using it locally not sure whether it should be DHCP or Static or other.
my wife and I both have samsung galaxy s2 smartphones that for the last 2 months since purchased worked fine when connected to the d-link network-suddenly,yesterday both phones disconnected and when we tried to connect and entered the WEP key that worked fine previously,neither would connect-I powered both phones off and on as suggested by ATT,but that did not work.
Me and my girlfriend moved into our new flat in September and since then we've been sharing my laptop as her laptop refuses to connect to our Wi-Fi, we are with Virgin Media and I have had literally no connection problems whatsoever but hers gives us various errors like 'No Internet Access' 'Local Connection Only' and sometimes it will connect for about 4 minutes and then just disconnects again, the only Anti-Virus she has running is AVG. It has also happened with friends who have brought there laptops over.
As soon as i modify my wireless to be unsecured, I looy ability to usse me the internet on all wired ports as well as all wireless. From the routers point of view it still has a good solid internet connection. Passes traceroute, but wont allow any wired or wireless connections on the internet. I'm trying to get a Linksys WRE54G v1 to work with this so my parents can have internet once more. If i manualy remove the security to allow the one touch Auto configuration button to work i loose my ability to surf until i run the Cisco Connection software to turn back on the passwords.
Before yesterday, there was 5 computers that our family used with access to the internet: one desktop computer with access to the internet via an ethernet cable attached to the wireless router, and 4 laptops- 3 dells, and one mac. All of them worked apsolutely fine.However, yesterday, my father brought in a new dell laptop. Once he connected it to our wireless, the internet on my laptop (a dell) stopped working. His new laptop coudn't get access either. Meanwhile, all the other computers had internet access.
