Hey all, I'm using a Belkin modem/router to share my adsl line between two desktop pc's. My intention was to run the primary one (my dear mother's) via ethernet cable and mine via wireless (I've been told I can't run cables through the house, doh!). As I barely managed to setup the router using the cable (apparently a common Belkin fault is that the router senses the cable is unplugged, even if it isn't...), we're both running wireless. No issues there then. However, with no ethernet cables attatched in any way the silly thing shows that port 1+2 are in use (green), and occasionally port 3 lights up orange (I assume in use but faulty?). My first question is 'why does this occur'?, and the second is 'should I worry about it?'. If it's not having/going to have a detrimental effect on our connecting to the outer world then I'm not bothered (it's not in my room so it doesn't bug me visually), but if it's a little dodgy obviously I'd like to try and rectify the problem! Yesterday (we've had it running around 3 days all together) there was a significant slow-down, resetting the router solved this. Coincidence or related? Hmmm... Thanks in advance for any help!

Thanks!

The only reason I didn't automatically assume the second set was bad is that on it's own it doesn't have a conflict with the bios, despite suspect running speeds. My friend had suggested that the timing between the chips may be an issue, though I'm not familiar with memory at this level of technicality, more reading is to be done! I had heard the Corsair RAM was of a good quality, which is why I bought that instead of the cheaper branded stuff (I can't afford real high end stuff mind you). I couldn't call Ebuyer yesterday, being a Sunday, but will do today.

Hey all! Not so long ago I purchased a ValueSelect PC3200 DDR400 512MB (double sided) chip, to compliment my existing two 256MB PC3200 DDR400 (single sided). I stupidly did not check my bios after doing this...A couple of weeks later I had a major system crash that wiped out Windows XP and even corrupted the maufacturers recovery partition (that was on the primary HDD as well). I couldn't install XP with the new chip in place, which raised the eyebrows, and led to me eventually realising it had caused the crash. When I installed XP I tempted fate and put the new chip back in, and checked the bios. It was listing all my RAM as PC2700, yet when the new chip was removed it correctly listed the remaining two as PC3200. Back went the RAM to Ebuyer, who said they tested it and found it faulty. I now have a new chip which I installed, only for the same configuration problems to occur. If it's on its own the new chip is listed correctly in the bios but the system runs about as quick as a 486, and if it's put in with the two 256MB it again lists them as PC2700. I've also tried all combinations of 256+512 etc, to get the same results. My system is a Compaq Presario SR1219UK, 2.66GHz P4, 1xIDE 40GB, 1xSATA 60GB, 1XSATA 300GB, with 4 RAM bays capable of holding a max of 4GB, I have the two 256MB chips in the first paired bay (though I don't think DDR DIMM's have to be in a any particular order?) and when it's in (which it isn't right now!) the 512MB goes into the first slot of the second pair. I've checked Compaq/HP's sites (and found the chips should technically work fine together), and updated the bios (which contained no mention of RAM conflict solutions) and trawled the web looking for comparisons, but I can't work it out. Sorry to witter on, but I figured I might as well get all the info down in one long winded go. Thanks to everyone who checks this out and thanks in advance for any help!

Hey Bookworm1x! If it's not an ISP problem but something on your end, the guys and girls on this forum are awesome with helping out, you're in the right place! Try running a tracert to this address (Start > Run > type 'command' > in the black command terminal that appears type 'tracert testmy.net' > copy and paste the results into a new post). That'll give the peeps here an idea of where your data stream is going.

Thanks for the advice! However, Everything in that department is ok, all is routed as well isolated as it can be. Plus it's exactly as it was when I was running a true 2Mb/s originally.

Just got off the phone with Ukonline, they got me to run the line providers test (British Telecom) which came up with the same (slow) results. Despite me paying for a half hour phone call something has at least been looked at, but it's now in BT's hands as it's their hardware and not UKonline's. If anyone in the UK is using a Broadband connection that runs through a BT line, these login details will get you to their line speed tester if it's any use: Username: speedtest@speedtest_domain Password: dsl URL: http://speedtester.bt.com If however anyone still has suggestions for my connection (as it may not be BT's fault) they will be appreciated! Cheers Trogers!

Strange thing is it only happened that one time, otherwise it's been consistantly between 500-750Mb/s download...

Sorry man, it's still blank; opening from location and saving to disk the same...Strangely though, the VanBuren one I had previously used is doing the same thing, so I think it's my end. I've restarted a few times to no avail...this is weird...

Sorry Trogers, but that file comes up with all the fields blank?

Hey all! Changed my ISP to Ukonline a while ago, and all was fine for a while. It's a 2000/256 connection. However, after a major issue my motherboard had with my new RAM (a Corsair 512MB PC3200 chip) and a bad XP crash I had to re-install from a formatted HDD. Now everything is back up and running I'm having trouble...
