I'm having an issue on our home network that is driving me mad.
More often than not, when a user on our LAN is downloading and using most of the bandwidth my connection my PC or my laptop or my brothers laptop drops.
It's not only when bandwidth is being used but it does seem to happen more often when this is the case.
As this affects more than just my PC I know it can't be PC specific (I hope, anyway).
The router WAS a Draytek Vigor 2820n and I blamed the router for the drops so I asked work for a new router and they were kind enough to buy me the newer model, the Draytek Vigor 2830n. Annoyingly, the problem still exists.
I've tried several things here to get this working and I've listed them below. I'd appreciate any advice that may help me fix the issue.
- Changed the router from a 2820n to a new 2830n, the problem persists.
- Reset to factory settings.
- Manually set an IP address and changed my PC name in case there were any conflicts with my previous wireless card.
- As above, I tried a USB wireless dongle, a wireless card and am now using an ethernet plug - I still have the issue.
- Flushed my DNS/cleared ARP cache table on router.
- Punched monitor.
- Changed my local DNS to use Google DNS.
- Upgraded to the latest firmware (on both routers).
- Disabled my wireless and used the ethernet plugs to run on a LAN.
- Replaced router power cable
- Changed wireless channel (several times!)
Now my last point is interesting. My brother had the same problems as I was getting but he switched to an ethernet plug and according to him he hasn't experienced any further problems so I thought "Ah, OK. Must be interference" and get myself an ethernet plug. Nope, I still get disconnections.
Also 90% of the time it's when first using the internet that it will drop and then intermittently after that.
I think that covers it, if I think of any more things I've tried I'll add it to the list.
Edit: By "ethernet plugs" I think I actually mean "ethernet adapters".
Edit 2: By editing the first time, I got disconnected when trying to save the edit. Good timing.
Edit 3: The only thing I can think of is the login/interface on both routers is very similar. Perhaps it uses the same firmware, and that firmware has a bug. The next step might be to trial a totally different make of router? I have now set the router DNS servers to Google DNS, still no luck. Update: Removed this now.
UPDATE: It definitely seems to happen more when a user is downloading on our LAN. If no-one is downloading we can browse fine. As soon as someone starts downloading (even about 10% of the entire bandwidth) it seems prone to disconnecting.
Now, one thing I have thought is my ISP is Sky and I replaced their horrible router with our current Draytek. I did read when I done this you aren't supposed to change the Sky router as Sky can detect this and complain or something along them lines. I wonder if the ISP could be causing this?
Update 2: Today I've had the exact same issues and I can confirm no-one is downloading at this time. 4 IP's are connected. I don't know if this is relevant either but it does also seem to me disconnect shortly after connecting back to the router after a short period of inactivity (e.g laptop to sleep for 30 mins > log in, browse literally a page or two and then bam > disconnected/hanging).
Update 3: I have switched the router back from a Draytek to our original Sky router. From tests yesterday, on my laptop and another laptop (wireless) we did not get disconnected once. My PC upstairs (wired) didn't disconnect either but did hang here and then. It seems there is an improvement but I wouldn't say the issue is fixed until I trial it for a few more days. As ever, I will update!
Update 4: Well, since switching back to the Sky router I've not been disconnected once. It's appearing that for some reason, both different models of the Draytek routers caused me grief, both with different firmware too. I don't know if this is because Sky can some how send 'kill packets' if they detect we aren't using their stock router or it's configured in some way to work with our line correctly, my networking isn't great. Providing I've had no disconnections following the next few days, I will end this question. I'll update in a few more days to see how things have gone.
Update 5: Well, even when switching back to the original router we started getting problems. The problem IS definitely worse when maxing out the download or upload. After several tests and changing equipment etc I've come to the conclusion it's the ISP/exchange at fault. There are no other answers. After reading a few threads, it seems a common problem with Sky Broadband too, see here and this. Thanks for all your help.
Ping results once disconnected (this shows a ping from the router, but I cannot get access to the interface on 192.168.1.1, it just hangs saying "connecting..."):
