A little while ago (maybe a few weeks), my internet suddenly got really slow on my on my PC (all other devices on the network run fine-wired or wireless-run fine) I've done research and tried a few methods (Hitman Pro, Fastcache, OpenDNS), and it got worse because now none of the computers can access the router's config page (192.168...). It is a belkin N router, and my problematic computer hooks up with a levelone wireless card. The wireless signal also gets dissapears occasionally, even though its fine on my iPod and PS3, running off wireless from the same location (well, the iPod can move, but you get the idea).
Anyway, thanks in advance, and sorry for a few examples of bad grammer.
I had a similar problem with my wife's comp not wanting to connect 'solidly' to our net via her Netgear wireless b/g usb adapter. Learned that for reasons only known to Netgear, this particular device likes to drop then pick up signal every minute or two.
Okay need network statistics... What OS is the problematic computer running?
Are you connected to internet through your ISP's Gateway device (modem)? IF so try dissconnecting the router from ISP gateway and directly connecting the problem computer via ethernet to the gateway device.
Check your internet connectivity. If it good, then it is not the gateway, could be the computer's wifi card.
If good then reconnect the router and try hardwiring the comp to the router. if connects fine then issue is with either the wireless settings on the router.
a nudge now and again.. remeber, we forum 'helpers' do have lives out in 'meatspace'.
When trying to access the Belkin's internal page, what kind of message are you recieving? a 404 error? or is the page displaying but you are 'locked out'?
Wireless N works on the 5.8GHz frequency band.. Many of the new wireless telephones also broadcast on this frequency. I have heard of 2.4 GHz cordless phones 'jamming' wireless B/G equipment.
Ummm... I am assumming there ae walls/floors/ceilings between the router and the problem child?
Is it possible that one of the walls may have heating ducts or even central heating/AC in/behind it?
Is the house's main wiring panel maybe in one of the walls?
I ask because it is very possible that that one particlar location may may be shielded from signal in that one particular spot.
Anyway, yes indeed there are, say, 3-5 walls/ceilings, and as far as other stuff, I have no clue, but that is completely possible. But as I failed at saying, even though the conditions were exactly the same, my PC suddenly became slow. The area between the computer and router didn't change, nor did the router, and nor did the computer. And the wireless signal didn't even get lower (it is still around 3 bars-which is what it was at before the issue). The internet (loading webpages/gaming) just got slow. After research I found out maybe it was some sort of virus or something, but Using my usual AV stuff (ESET Nod32 AV (not smartsecurity or whatever the other is)) to scan, and then trying Hitman Pro for free, turned up no results (scanning). So, basically, I'm confused.
Well, on the bright side, I can connect to the Router's page again, and the problem may have been me putting the wrong IP, I don't remember. Anyway, I messed around with a few things and only managed to make my iPod not find the router and possibly make the connection worse wifi-wise. That'a about it-thanks in advance as always.
In computing, there are two realms, so to speak.. Cyberspace ( the 'reality' of data on networks including the internet) and 'Meatspace' the world of flesh and blood ( and piss poor weather).
Is it possible that someone (ones) is also borrowing the signal and consuming bandwidth?
OK, well, I reset the router from the page (192... page), and re-ran the Belkin disk, and that at least lets me use my iPod again, but my PC still is at the same, slow, annoying connection, so, as I have always been, I'm still stumped.
Ok, so I was just trying to make my PC share it's connection (which would allow me to use my iPod to test whether the problem only affected the computer's speed or if there was trouble with the connection), but it gave me an error when I was trying to close the properties thing for my network (which would send ICS to work), so that test failed without starting.
Sorry to bump (again), but this issue is SERIOUSLY annoying. I'm starting to suspect it's something in the wireless adapter (the PCI thing), but I can't see what would be wrong with the card itself, and I reinstalled the driver, so that can't be the issue (it's the latest one).
I should add, the signal (bars) are good, usually between 3 and 4 of 5, just the internet loads super slowly. And as I said, It used to be fine, but then it just suddenly was messed up, with nothing having changed whatsoever. It probably isn't a virus/other computer hurting thing, I've scanned with multiple applications (Eset Nod32 AV, Avira free, Hitman Pro)
Anyway, incase it'll help, here's the full list of things:
Router: Belkin F5D8236-4V1 (01) (broadcasting 802.11b,g, and n)
Adapter: Level1 WNC-0500 PCI card
Problem Child (Computer): Compaq SR5333WM Desktop running Vista Home Premium 32Bit
Oh yes, another note, I was trying to setup file sharing so that this computer could be accessed by a Mac Running Tiger, and although the settings seemed correct, nothing appeared on the Mac (in the network folder thing).
Internet suddenly VERY slow
