What is the cause of periodic disconnections? I don't know what kind of information I'm supposed to give, but I can say that the internet disconnects randomly but connects again.
View 2 RepliesHardware: DIR-615 @ 3.11NA firmware
Wired:
PC windows 7

Description:Everything wired always works, the dell wireless always works and HPa always works along with all of the cell phones. HPb will connect to the router always, as in it see's the router and connects using AES security. For between 15-30 minutes everything will work correctly, transfer speeds are fast and everything is working. For no reason the laptop will lose "Internet connection" only, NOT the connection to the router. But all of the over devices continue to work correctly, so i know the router has internet connected.i would have to disconnect from the router and reconnect and that gives me another 15-30 minutes of connection. I have checked a load of stuff, but i cannot figure it out. Here is a netBIOS

View 19 Replies View RelatedI have installed 4 of these units in a commercial premises offering free wifi. Since the day they were installed (5Months ago) we had connectivity issues with mobile devices. This was somewhat resolved in the latest FW 1.0.04 but we are still having random disconnections on the units every 2 - 4 days and have to reboot the units. Lately the units have become unresponsive and reset themselves back to factory settings.
What we have done so far:
Changed router models - No change
Changed from Static IPs & DHCP - No change
Turned on isolation - No change
Performed a wifi analysis to pick the best channel for each unit - Slight signal gain but still disconnects
Changed to 20Mhz only (And all other variations) - No change
I think I am left with no option but to return these for some other brand. I'm really regretting buying these units at the minute...
For the past day or so I have been having problems with my internet connection to my PC. It has been working fine for a few hours, then it suddenly goes down for up to 30 minutes, with sporadic (lasting about 30 seconds) reconnection during that 30 minute period.I am pretty certain this is a computer related issue (as opposed to a problem with the modem), as none of the other computers in the household. (Ihave been affected, and neither has the wifi (I have browsed on my phone while the internet on my computer was down, in fact am currently writing this post on the wifi while my computer has no access)My computers specs (Taken from the sys info program when I regained connection for a short while) [code] Steps I have already taken in an attempt to solve this problem
1. Reset modem (turned it off and back on again)
2. Ran most of a virus scan in both macafee and avg (they both got to about 85% and by that point were just scanning steam stuff
3. Talked to a verizon tech, confirmed it is most likely not a modem problem (he didnt know what the problem was however)
4. Changed out the ethernet cable, the new one works no better than the original
Additional note: Earlier today (after these problems had begun) I was downloading the latest version of hamachi from a site soft32.com when I recieved a trojan warning from macafee. I immediatly stopped the download, restarted my computer and began scanning with both AVG and Macafee, neither found anything of note (AVG found something it labeled a hidden directly, I looked it up and it seems harmless)
There are times the Nexus CPU goes high around 70% but its not a constant occurance. Is there something to worry. Quite hard to find out which process caused it as it happens very brief. [code]

In both cases, when I ping my IP's speed test site, I get a solid ping rate of approximately 17-20ms but i also get about 5% failed: timeout's. Now I've seen posts here that suggest wireless interference could be an issue but since my desktop is hardwired into the router, that source would seem to have been eliminated. When I connect my desktop direct to the cable modem the problem doesn't occur.

We sort of recently got wireless internet, have had it for 2-3 months now I think and everything was running smoothly. Yesterday my internet randomly disconnected and it was only from this (my) pc, the internet was fine for everything else in the house which includes another pc, 3 laptops, cellphones, ipods, and gaming systems. It has been going out randomly since maybe 6pm yesterday. I have to completely restart my computer for it to work again. The only thing I tried was to unplug the modem and router for a bit and plug them back in, which did nothing for my computer lol. When I did that though the other computer had an ip conflict that came up which it's had in the past with my own pc but after I restarted my computer they were both fine. My computer still has random disconnections from the internet though. I don't understand why my computer is the only one affected and why it's starting now when it's been fine for the 2-3 months it's been working.

Ive been through 5 routers. All of them, except ONE has had a very annoying problem. The WiFi disconnects like anything randomly. The funny thing: The 4 that disconnect have all been working on 802.11n 300mbps. The 802.11g DG834Gv5 is as solid as a rock, maintaining connection for months on end, no wireless dropouts. Ive tried fiddling with the 4 routers (DGN2200, DG834N, Belkin N1 Vision, and another one ive forgotten), putting them onto 54mbps, which always works perfectley. When its on 145mbps or 300, they disconnect. No pattern, just fall off. When reconnecting, I can see them in the network selection thingy, but it just gives me the error 'Cannot connect to XXXX', only solution is to turn off the wireless radio and turn it back on via router interface.

All of my other devices (that are connected via wireless) still hold the connection with no issues. I've checked the cable, unplugged/plugged back into the router, and it shows connection on the network card on the back of the computer.I have used the system interface to ensure the address is a valid one. I have powered up and down the computer multiple times and have also powered down and up both the router and the cable modem.

View 5 Replies View Relatedat our office we've recently upgrade from a old consumer-grade linksys wag200g modem/router/ap to the Cisco SRP527w. The Cisco is suffering from very frequent ADSL disconnections. These disconnections happens when there is some traffic to the internet and they seem to don't affect the LAN routing: on the weekends there are no disconnections at all while during the working hours there may be disconnections every FEW MINUTES making this router unusable. Often these disconnections force us to do a full reboot of the router.
Firmare version is SRP520W-1.1.19, the latest. ADSL line is a 6Mbps/640kbps. Noise margin is about 11dB for downstream and 20dB for upstream.
No voice line is used and therefore they are both disabled. 2 wireless network are active. The old linksys was (and is) working correctly, no adsl disconnections at all. Never.
I have setup the existing wifi router (couple of years ago) so do have the basic networking knowledge but am not up-to-speed with all the latest developments in the industry2. ISP have provided a '******' ADSL modem that i need to connect to get this whole netwrok working. its only supports ethernet connections - (i live in a third world country)3. I have installed a TP-link Wifi router (WR841Nd). The modem on stand-alone basis is fairly decent, covers decent range on ground floor (my house is fairly big and is double story building) but with few dead spots. It supports N series so speed is quite good as long as one is within range.
Problemi have been living with it for couple of years but since recently i have been experiencing a lot of drop-outs/random disconnections and slow speed. I have tested my wifi router at friend's place and it showed no signs of problems so it has to be my ADSL modem (phone line is fine, though i am not close to exchange but that is not an issues as my neighbours are using the same phone line/ISP and they dont have an issue)another problem i have is the coverage, my current wifi only covers the ground floor and i would like to extend this to upper portione am looking to change my ISP provided ADSL modem. The problem is i dont know if i buy an ADSL modem off amazon and whether it would work or not because the setup is not straight forward and the ISP staff is corrupt. They dont provide with quality hardware neither do they have technical competence so i literally have to beg them at time to at least come and see the problem.Question1: ISP provided ADSL modem replacementi know the settings for ISP modem so i can search how i can replicate the same with Billion but can this work?Question2: RAnge ExtenderI am thinking of buying couple of powerline wireless extenders from netgear.
this had happened for a few months and i did not really mind until the disconnections worsen. usually when i power on the router and started using the internet, it will disconnect randomly once. my wireless SSID will disappear and lost connection. and no matter how i refresh the SSID still won't broadcast.
the only way to get back internet access is to re-power on the router, so the SSID will be broadcasted again.
my wrt54g2 V1 router had recently upgrade to the latest firmware version,1.0.04. but still disconnects as usual. however the disconnections only happens once, after u re-power on the router, you will not disconnect again.
but after turning off my laptop, and use it again after few hours, the same thing will happen again, a random disconnection and got to re-power on the router.
- Small Home-Office network based on a Cisco WRV210 VPN Router connected to another WRV210 in a remote location.
- The WRV210 provides 2 WAP-protected SSIDs, one for the office network and one for visitors
- Wireless channel is set 5 channels away of the closest networks (using inSSIDer)
- There are about 12 wireless devices, 4 connected to the office network the rest to visitors. Not all devices are connected at the time of failure. All wireless devices use DHCP which is set to last 1 day and provide 100 IPs.
- The wireless devices are 1 desktop, 3 notebooks (all clean), iPads, iTouch and Nook.
- The failure symptom is that almost daily, and most likely around the same time, no wireless device can connect to any of the SSIDs unless the router is power-cycled. During the failures, which we have witnessed first hand, there are no apparent reasons: no new SSIDs, now SSID in close range on the same channels, nothing we can easily observed in the network in terms of connections or unusual activity.
- A weirdo also presented by the WRV210 was that its web pages were shown erratically. That was corrected by downgrading the firmware from the latest to previous version.
We have used a loaner Linksys router WRT54GC with only the visitor Network on it and even though the situation is not as frequent, it has happened already a couple of times.The WRV210 is out of warranty and discontinued, so we get no support from Cisco that is worth paying for.
I have a 2 computer connected to the WRT54GS which is connected to the RCA DCM 425. It was initially fine, however now the internet is disconnecting at an absurd rate, at least 3 within an hr, sometimes more, and the only way it would reestablish connection is by unplugging and replugging.I have called time warner's customer support and they said it was because of the router. I have searched through various threads and saw and some had similar problems, but they were related to wireless instead of wired ( my case) so is there some settings i can change within the linksys to minimize the amount of disconnections? Becaused based on the log from the RCA,it seems that they are not reading each other too well. Are there any other routers that may establish a connection better than the GS?

The access point (a TP-Link WA801N) is only able to access the internet when it is plugged into a port that is on the default VLAN (PVID 1). If I plug it into one of the other VLANs then any clients connected to the WiFi lose access to the internet and cannot access devices on the VLAN.
