Trouble accessing certain internet sites

[Zamt]

I have a bit of a strange issue. I cannot connect to parts of a couple of sites. I can connect to most of the site, the ping is good, my friends can connect at the time I am trying to access, etc. As an example, I can get on to chase.com and navigate all over the site, but if I try to log in to my account, it times out. I can get to Yahoo, play games, do searches, but I can't get to fantasy football. eBay pretty much doesn't ever work. I have Cox cable internet, a Netgear router (I don't remember the model, it's an 802.11b wireless 4-port router with the latest firmware), Win XP Pro with all updates. This issue has been going on for over a year, and seems to be getting worse. I could get to fantasy football on yahoo last year, and I used to be able to get to hotmail, and now I can't. Any ideas on cause/solutions? I don't have a software firewall either.

Sounds like you're dropping a lot of packets
try this:
Start -> Run -> "cmd" -> OK
"ping google.com -t"
Hit ctrl + C to cancel it after about 3 minutes.

Between 90-100% of your packets should recieve a reply. I'm guessing you're losing more than that 10%....

Regardless of whether I'm right or not, I'd trade NICs first and then try the router.

Hey Zamt,

I have the same problem actually, it just started happening with my network. I can go to every site except 2 or 3.... one namely is peoplesoft.com.

I think my router is screwed. It also is a Netgear. I'll get back to you on the model.

edit: I only dropped 1 packet to google.

 

[Zamt]

I ran a ping on about 7 sites, including those I have trouble accessing. I didn't drop 1 packet to sites I could access, but those sites or portions of sites I couldn't get to before, I dropped 100% of packets. So it seems to be an all-or-nothing kind of issue. I couldn't even ping eBay.com

TRy setting the MTU on your router to 1492, or even 1400 to start. Frequently, the additional overhead of SSL, Proxies, and the like will make the packet too large. Many protocols cannot allow fragmentation to occur (usually encryption / SSL) so the packets are dropped.

Give it a shot.

I changed it to 1400 but still no go... seems like that should've helped out.

I have the Netgear MR814

Check your hosts file. There are a couple of trojans that add crap there to limit access to sites they have issues with (google most often).

For some reason my MTU was set at 1000. No idea why. I just set it to 1500, and I can get to everything! Thanks a lot ScottMac. I did the opposite of your suggestion, but you gave me the idea. This has been annoying me for a year.

 

[Schoolies]

Yep, mine works too... although it wasn't the MTU...

My brother said the firmware was up to date and I foolishly believed him!

Thanks
