Any Help With Passwork not Working

[dennphill]

Home Wifi network working just fine. Password with WPA2-PSK key was set up and working fine at my office desktop with a TP-Link N-router, TL-WR1043ND...and connects OK for my laptop by Wifi. Also works fine with my new TV (smart LG 47LM7600) which I put on the Wifi network, as well as my Sony BluRay player that is also connected by Wifi...and also my new ROKU XD HD player in my bedroom Wifi connection for that TV. Six months ago I bought my wife a laptop and it works fine on the Wifi network on her desk two rooms away from my PC and router. Here's the issue: Several months ago my father-in-law came with his laptop and we set him up with the Wifi password - worked OK till the last day he left. Since then, he cannot log on to the Wifi network. His laptop sees the network, but when he puts in the key (password) it says it cannot connect to the network. I put in the password and it say the same. BTW, my brother-in-law was visiting a month or so ago - same problem...cannot connect to my Wifi network. Father-in-law visiting again for a week and I'd like to have him connected. Any suggestions? [FONT=&quot]Network is fine...just some visiting laptops can't seem to connect. I am certain of my password. Multiple tries don’t change anything. To show my father-in-law the password, I started up my laptop (on the wireless network) to show him the password. So it’s not miss-typing errors. I don't want to reset up the whole home Wifi network with another password. Any ideas? [/FONT] What's the problem when you put in the correct password and laptops won't connect? Thanks for the attention.

Do you have a limit on the number of allowed devices/IP addresses on the router? If so, you might be hitting that limit so "new" devices can't connect even with the correct password.

Thanks for the attention, Fardringle, but I don't think that's it. The TV is only on the network when it's accessing the WiFi for download, or HULU+, or such...usually it's just a TV with Cox cable providing programs. The BluRay player, while connected (it has a good connection) is usually off...as is the ROKU box in the bedroom. Generally only one or two devices on the WiFi network - I think the TP-Link box says it can do 255 (!) connections or some such. I'm not a techie, but once I set this up and it's working, I don't want to muck about and screw things up. I guess I could see if the router has latest firmware, but it's been up and running since I set up a year ago. The only issue is that a couple of 'visiting' laptops see the network and when they try to access it, entering the (correct!) password gets a 'can't connect with the network" message. I think I will try and contact the TP-Link support and see what they say. Thanks!

It does sound like the DHCP server is running out of spare dynamic IPs to lease out.

Set your lease times to 12 hours or so, and check the total number of IPs in the DHCP pool.

Was the wireless MAC filtering enabled to deny access to the wireless?

...MAC filtering is not enabled. (Fixed father-in-law's access issue with stop-gap measure. Had a long blue LAN cable I stuck in my router and told him to plug his laptop into it to check his email, etc., etc.) Still don't see why one laptop can't access the wireless network. Laptop sees the network. Passwprd entered, then laptop says "cannot connect." ?

I don't have a clue as to how the router (TP-Link TL-WR1043ND) runs out of spare IPs with only my wife's Toshiba laptop in the bedroom and my Toshiba laptop (usually off) in the office/bedroom where the router and my desktop are located. That's only two dynamic IPs, I think. And I'm only asking for one more for the father-in-law's laptop. The other devices that occasionally are on line (and usually only one at a time) are a LG smart TV (which I've decided is really not very smart and a pretty stoopid purchase - 2013 LG 3D 47LM7600!), Sony BluRay player at the LG TV...and a ROKU player at the TV in the bedroom. If I had them all on at the same time it'd only be less than half a dozen dynamic IPs in use...a newer N-router can't accommodate that?

I'm showing my ignorance - well, lack of education, maybe - but I don't know how to check my lease timeing or how to see how many IPs are in use in the DHCP poll, but as soon as my father-in-law leaves (after Easter), I'll go online and see if I can figure it out, then log into the router (?), and check it out. Thanks, though for the suggestions.

Logging onto WiFi shouldn't be this complicated or so much effort. I probably am doing something wrong but I can't figure it out.

Get into your router's web interface by typing its IP address in a web browser. There, you will see how to check for lease time and how many IP addresses can connect to your wifi. It shouldn't be tough, just look for it.

Your router IP address is the address of the default gateway you see when you type ipconfig in a command prompt.

I agree. Running items that stay in the house to a static IP might help as well.
