Asus A53SV Loses Connectivity Upstairs After Sleep?
Oct 25, 2012
Major symptom: Maddeningly intermittent wireless issues with Asus laptop after repair. Unable to connect to network after sleep or reboot on upper floors of house.
History:
1) Laptop wireless was working fine but power jack and case were damaged.
2) Sent away to Asus for free repair (pulled the HD first).
3) Got it back and seemed fine, but...
Problem:Wireless starting dropping after sleep. It's my wife's laptop and she usually uses it on the 2nd floor of the house.Routers are on the first floor. It failed the same way on both my G and N routers. Played with all sorts of settings, disabled IPv6, reinstalled drivers, checked for BIOS update. No luck . Eventually saw some event log entries that might have been associated with a bad wifi card. Ordered a new Intel 100 N (OEM model) and replaced card, same issues. Swapped card with a Broadcom 1510 from an old Dell I had. Same problem.
Tried more settings, static IP, flushing DNS, etc. Same problem.At this point the event log has nothing notable in it, no error logs anywhere the wireless card will just report no connectivity.when I work on this laptop I take it down into my office, which is on the 1st floor by my router. The laptop works flawlessly there (10 feet from the router). So my theory at this point is that Asus damaged or otherwise messed up the laptop antenna while repairing the laptop. most of the time on the 2nd floor the windows wifi icon reports a perfectly good signal, and if I boot the laptop on the first floor and walk upstairs, the laptop works fine(as long as I don't reboot or let it go to sleep).

Model : TD-W8968
Hardware Version : V1
Firmware Version : 0.6.0.1.1 V0005.0 bld 12016 rev 48690
ISP : Talktalk
yesterday (GMT) I received and installed my new TD-W8968 from Amazon and seemed to work a dream.. until today. The router connects to my desktop PC via a wired LAN connection but uses the wireless for laptop, TV, smartphone etc. Today I notice that when my PC wakes from sleep the LAN connection is lost. None of the LAN lights are on. And also there is no wi-fi connection either and even though WLAN light is on there is no signal at laptop. Setup is pretty much out of the box though I did reset channel to avoid conflicts locally. This is set to 7. The PC LAN adapter is enabled and ready but no apparent connection to router. I changed the router LAN port and that seemed to work but after I had the problem again this change did not work. I changed the LAN cable and that seemed to work until next sleep! Then fail again!
Is there anything on LAN adapter or router that needs changing? Am I on the latest firmware and would an upgrade fix this?

I use a WUMC710 bridge with desktop PC and a Printer connected to it. When those two devices have been inactive for a while the bridge goes into sleep mode and loses the connection Back to my EA6500. Trying to print something from wireless devices connected to the 6500 elsewhere in the network doesn't "wake up" the bridge. Ihave to unplug the power supply and restart it.

Just installed a new WAG120N for a customer.All works fine except when I go to her sleep out, not more than 6 meters away - no connectivity through wireless, so bad that it doesn't even see it - this is with two separate laptops.The walls are nothing special - wood outside, wool fiber insulation & gib board inside.Roof standard corrugated iron.

I have a new Linksys E3000, 2 wired disktops (1 windows 7, 1 windows vista), 2 wireless laptops (both windows Vista), whenever the computers power down into sleep mode and are woke up, I have lost my connections to the router and I am forced to restart the computer. I've been told by one person that this is a problem with vista and windows 7, but wouldn't that have been a problem with my old router also?

My internet connection goes up and down. After further investigation, I've noticed that as soon as i receive a certain # of packets, the internet connection goes down. It may be a process or application that is taking away these packets.

Having just received a new Dell XPS8500 running on Windows 7 and I have the following problem: My wifi connection is turning off and the name of my network is no longer displaying in the list of available networks. This means that I am unable to access the internet or emails rendering the computer unusable as I am not on broadband (using access from another router close by). It is absolutely critical that the wifi connection is always on.

This is my network topology. Sometimes it just suddenly loses conenctivity or traffic for unknown reasons, like the internet hangs for much time or maybe some routers just stop responding, even restarting ! Do you think there should be a Multi-WAN router that could take 4 WAN lines and give one LAN to plug at a switch for a better performance ?I know that my setup is wrong, give me your opinion about it and how to fix it .

I have a client who has 4 computers in the house all running wireless. 2 desktops and 2 laptops. One of the laptops is running XP and after 5-10 minutes of surfing, the internet stops working while all the other computers retain a good internet connection. Repairing the connection via the taskbar icon fixes it temporarily until the issue reoccurs.

ATTACHED: My current running config with sensitive info taken out.
I have a Cisco 881 Router connected to cable modem. The router is running IOS 15.1.
I have it configured exactly the same way as an 877 router running IOS 12.1 which does not exhibit the problem. Just a standard LAN/WAN config with basic routing/firewall.
When the internet connection is lost for any reason and then re-established the router will no longer pass internet traffic unless I reboot the router.
I used Cisco Configuration Professional to configure the router. The key setting seems to be the Router Static Route. We have a static IP and I set static route with the "make this the default route" checked. Then I set forward (next hop) to the IP my ISP gave me as their gateway.
This is exactly the same way I set the 877 router using the same ISP but in a different office.
Every so often the internet is lost due to power outage or the ISP doing something on their end and every time that happens we have to reboot the router which is quite annoying.
I did not have the "permanent route" check mark checked but I do not have it checked on the router that does not have the problem either so I don't think that's it.
When I set the static route to "interface" then added the static IP of the next hop it will continue to work for incoming connections but not outgoing.

My primary home machine loses network connectivity for a very brief moment once or twice a day. Here's what I've observed over the past few months:
Seems to happen every 12 hours after a restart Disconnect is very, very brief. Putty sessions, online games, or other applications that require a consistent connection disconnect but it's rare that I can see a ping fail when everything else disconnects.Does not coincide with network problems on other machines (Xbox/media PC/wife's PC).
Other details about my system and home network:
Windows 7
Asus motherboard (couple generations old) with onboard ethernet
Ethernet > wired hub > wireless router > cable modem (wife's PC is connected to the same hub and does not have the problem, at least not on the same schedule)
Things I've tried (and will probably now try again just in case)
Restore network card driver (I'm in the process of finding a specific one for my motherboard)
Tinkered with power saving settings in the ethernet card drivers.
Fully up-to-date Windows install.
Static IP address reserved by the wireless router running DHCP
I'm not 100% sure, but I think this problem persisted across Windows OS upgrades (from Vista to Windows 7 a few months back)
By far the weirdest part is that it seems to happen every 12 hours. Like clockwork, I can predict that I'm going to disconnect from any persistent online connection if I know the last time I restarted my machine.
Solved:I caused my own problem long ago when trying to set static IP addresses in my home. I have a Netgear Router (WGR614v9) and I played with the Address Reservation feature. In addition, I manually set the IP address I wanted to have on my machine using the normal network card properties. Setting the IP address manually is what seems to have caused the conflict.
Finally looked in the Windows Event Viewer and the culprit was quickly identified. At time of restart and every 12 hours later, the following error appeared:
The IP address lease 192.168.1.20 for the Network Card with network address XXXXXXXXXX has been denied by the DHCP server 192.168.1.1 (The DHCP Server sent a DHCPNACK message).
I accidentally fixed it for all affected machines by changing the start address of the DHCP server on the router (increased it from 20 to 30). That seemed to kick all the manual entries out and set them back to automatic obtain mode.

I'm using this router for connecting 2 PCs, one lap top and few mobiles.The LAN network is always stable and never loses connection, but I'm having problems with the wireless connection. My lap top runs on wireless, and 3 Android mobiles, an xperia mini pro (problematic), xperia Tipo and Alcatel OT-908F. Almost always when I login to facebook on any of the mobiles, pictures won't show, and also youtube videos thumbnails won't show. On the xperia mini pro after 2-3 minutes of surfing, or doing anything else the connection drops, and then the mobiles can't see the wireless connection. My lap top can see it, but it cannot connect. After restarting the router everything is back to normal.

In my LAN, I have always been used an Aironet 1250 for internal use and always work fine. Now, I added a 3com AP but both AP are not correct. When I turned off the AIRONET 1250, the 3COM AP settings works fine. When both are turn on, the 3COM AP loses connectivity all the time.I have heard about the overlapping channels in 802.11b/g networks.

Internet connectivity on my laptop is lost shortly after beginning to upload/download files over the internet to my cloud storage provider. I also lose connectivity when transferring files to or from the laptop within my LAN to a desktop computer connected via wireless router as part of a workgroup. Connectivity is only restored once I restart the laptop or uninstall, then reinstall drivers for my wireless network card. The issue then reoccurs once file transfers begin again.The laptop is running Windows 7 Home Premium SP1. The driver for my Intel Wireless WiFi Link 4965AGN internal network adapter are up to date. I have a Linksys WRT610N ver.2 router, and an HP Pavilion dv6500 laptop.

I'm currently implementing Microsoft System Center 2012 Operations Manager, the curent stage of the project is to add the network devices to SCOM via SNMP in order to monitor them, I am able to add them all and monitor; however, my ASA 5510, although SCOM discovers the ASA via SNMP and adds it to the network monitoring list, it loses SNMP connectivy every 30 minutes, and 15 later it reconnect with SCOM, then after another 15 minutes it loses the connection again, and so on and so for.

I have a new EA3500 router that's working great for a variety of devices* except a Windows7 laptop. 24 hours after establishing a connection, the laptop loses connectivity and it's very difficult to re-establish a connection. Usually I have to reboot the router, but 24 hours later the problem returns and Windows is unable to connect.
My router settings include DHCP client lease time set to 1440 minutes (24 hours), so I thought the problem might have something to do with DHCP lease renewal. To test this theory, on Saturday night I did ipconfig/release and ipconfig/renew and established connectivity from the laptop.
Sunday morning I spoke with Linksys support and changed several settings per their recommendation:Network mode mixed (I had it on N-only for some reason)Assigned different SSIDs to the 2.4GHz band and 5 GHz band2.4 GHz band channel is 20MHz only, using channel 95 GHz band channel is 40 MHz only, using channel 161I also power cycled the router. Everything worked fine until Sunday night, 24 hours after the release/renew, when I lost connectivity. I am not sure what to try next and whether the problem lies with the router or the laptop.

I'm having an issue with the connectivity of my wireless internet. Downstairs, everything is peachy. Upstairs, which is no more than 100 feet from the router, the connectivity is non-existent. That is - the laptop still registers full signal strength, and identifies my computer as connected - but the browser constantly loads, google talk is always trying sign in, and my dropbox continues to try and find a connection.The page never actually loads, but it also never tells me there is no connection. It's like the date has slowed so much that it is not actually being sent.

My uncle has just received broadband. We have a router which is connected to his phone line, but the computer is upstairs. We have measured it and it needs 20 metres of broadband and ethernet cabling to fit. Once we get these cables, can it just be connected as the cable is going to go up the stairs and is hazardous

I have a wag320n that works good on ground level, but the modem is standing in mt technical closet where i think is a lot of 'interference' that degrades the wireless signal. So upstairs i am alos working with a wireless...kind of tv server that has a very poor signal from my wag320n. I want to boost that up a bit by using a wap54g on the attic. But i cannot get it to work....it only gives a a wireless signal from my wag320n.

If you have two Linksys routers, an EA4500 and an EA3500, can the EA3500 be used upstairs as a bridge for the EA4500 downstairs?

I have an ASUS Z77 Motherboard and when I install the AI Suite II which comes on the installation disc it blocks my internet connection. When I uninstall the software my connection is fine. I am using an Ethernet connection by the way. I think it is being blocked by the component called Network iControl. As soon as that component is uninstalled my Internet connection comes back. I want to have the software, but I also want to have my connection.

I recently moved into a larger 2 story house, and for the first few months I was using a Linksys E1000 I've had for about 2 years now. It's a fine single band router, but the people upstairs and the xbox/PS3 in the living room didnt have the strongest connection.
I shopped around and finally got a ASUS RT-N66U for a really good, strong dual band router that would supposedly give better range and performance than my old E1000.
Unfortunately, since I got it everyone is having issues they never had before, namely:Signal dropping all around the house and having to search for the network much slower performance than before the xbox/PS3 cant hold a stable connection even for a few minutes now, when before you could watch Netflix HD programs easily
I've upgraded the Firmware to 3.0.0.3.178 since I heard earlier firmwares had issues, but other than that and opening my ports for qTorrent it is relatively stock settings.

I have a Win 7 laptop which keeps dropping its network connection. I have changed the power management option on the network card so it can't turn itself off, but it still goes to sleep after a certain amount of time.I've also tried with a different docking station and network cable in case that was an issue, but the same thing happens. Event viewer does not reveal the cause of the drops.

My mother's ISP is an AT&T DSL connection. She just had her PC connected directly to her modem for several years, so I eventually got her a router so when her kids and grand kids came to visit they could use wifi. It was a very basic and inexpensive Belkin model, but I don't recall the model number. The problem was the Internet connection would become inactive every time the desktop PC that was connected to router via Ethernet would go to sleep. The only way to get the Internet connection back was to wake up the desk top PC. I checked all of the router settings, googled to see if I could find similar problems, etc... and never could fix it; so I eventually set up my trusty old wrt54g at her house. It worked fine in my home for years; and when I set it up at her house, it still had all of my original network settings in it. I just changed the network name and password.But the same issue is still there. Every time the desktop PC goes to sleep... The router loses Internet connection and does not get it back until the desk top is made active again
